I was thrilled when the new edition of DASH Diet for Dummies came out and I actually had it in my hands! I received a complimentary copy from the publisher and was eager to post a review on Amazon. Imagine my surprise when I was blocked from writing a review, not only on my own account but also on my husband’s Amazon Prime account. Both times I received a message, “We apologize but Amazon is not accepting reviews on this product from this account. If you would like to contact us about this decision, please email email@example.com.” I did email “community help” but they never responded. Next I called and spoke with an Amazon customer service rep who told me that someone would call me the next day to discuss it. No one ever called. Finally, I decided to outsmart Amazon and create a new account using an alternate email address. Once I did that, I discovered I had to spend $50 before I could review a product. So I bought a Valentine’s Day present for my husband along with a copy of DASH Diet for Dummies, Second Edition so I would have a “verified purchase” when I wrote my review. Of course, this did not qualify me to immediately post a review. I had to wait until several days after the order was delivered before I could do that. But once they allowed me to, I was thwarted once again. I received this message:
“Thank you for submitting a customer review on Amazon. After carefully reviewing your submission, your review could not be posted to the website. While we appreciate your time and comments, reviews must adhere to the following guidelines: Amazon Community Guidelines.”
Frustrated but undeterred, I decided to circumvent Amazon and post my review as a blog and promote it widely on social media! So here it is, in all its Amazon “illegal” glory!
As nutrition communications consultant, I daily translate technical scientific nutrition information into practical, consumer-friendly messages to help folks enjoy food without fear. The authors of this new edition of DASH Diet for Dummies have successfully accomplished this. They explain the science of high blood pressure in clear-cut, straightforward terms; provide practical, creative ways to make the DASH Diet a part of everyday life for busy people and transform the guidelines into delicious recipes that are easy to prepare. Having known Cindy Kleckner for over 40 years, as she transitioned her career from clinical practice to culinary nutrition, I’ve seen firsthand the love, passion, creativity and care she puts into each and every dish she creates for family, friends and her many culinary presentations. It is truly her calling. In addition, Rosanne Rust and I have worked together with many of the same clients for over 10 years and share a fervor for promoting accurate food and nutrition information, as the authors have done in this book. Finally, their colleague, Dr. Sarah Samaan successfully breaks down the medical perspective on high blood pressure in a practical way. I highly recommend this book not only for people looking for nutrition guidance to manage blood pressure but for anyone interested in an eating plan that provides a balanced variety of delicious foods to promote health and nutrition. It’s DASH: Delicious And So Healthy!

I am in my second year as an invited Produce for Better Health Foundation volunteer Fruit and Vegetable Ambassador. In this role, I promote the fun, flavor and benefits of produce in a variety of ways every month. This is my January contribution for which I received no financial compensation.
For many folks, kicking off a new year means making resolutions, often admirable but frequently difficult to maintain. In fact, just 40% of us stick with them for 6 months and a mere 19% for 2 years according to University of Scranton psychology professor John Norcross, PhD, who has studied compliance to New Year’s resolutions,
One strategy that may help is making resolutions more achievable. Aim for evolutionary change, not revolutionary change. Making small steps will add up to big changes over time. This makes them less daunting.
As a registered dietitian nutritionist, one of my goals is to find ways to encourage people to eat well-balanced, nutrient-rich meals and snacks they will enjoy. We all know eating fruits and vegetables is good for us but it’s still where most people fall short. And this is confirmed in the new 2020 – 2025 Dietary Guidelines for Americans, which say 75% of Americans are not eating enough fruits and veggies.
But how can we boost fruit and veggies in our meals so it’s less of a challenge and more of an easy and natural part of everyday life? First, don’t think of them just for their health benefits but focus on the fun, flavor and fitness potential they also provide. Then find easy, tasty ways to do that.
While the Dietary Guidelines recommend 2 ½ cups of veggies and 1 ½ cups of fruit a day, you don’t need to achieve this the first day. Instead, start slowly and make just one change each month over the next year. Rather than resolutions that go by the wayside, create “plant-entions” that are easy to stick with. Here’s a month-by-month guide with ideas.
January: Add a fruit or veggie at breakfast. This can be as easy as drinking a 6-ounces of 100% orange, grapefruit or tomato juice or adding banana, raisins or another fruit to your cereal.
February: Add a fruit or veggie at lunch. Layer a sandwich with lettuce and tomato or add sliced pears to a grilled cheese sandwich, opt for a small salad with your meal or grab a piece of fresh fruit for dessert.
March: Add a fruit or veggie at dinner. Double up your veggie intake by topping a baked potato with steamed veggies and cheese or a heaping helping of salsa. Or how about a green salad with fresh or canned peaches or pineapples slices topped with cottage cheese?
April: Eat a fruit or veggie for a snack. Keep small boxes of raisins in your desk drawer at work or stuff celery sticks with spreadable cheese or peanut butter.
May: Sneak in a fruit or veggie at breakfast. Scrambling up some eggs? Stir in canned diced tomatoes and green chilies for added color and flavor. Or spread your English muffin, bagel or toast with mashed avocado in place of cream cheese or jelly.
June: Sneak in a fruit or veggie at lunch. Add diced celery or apple to tuna or chicken salad or zap a half cup of frozen blueberries or other frozen fruit in the microwave at 50% power for 45 seconds and combine with yogurt.
July: Sneak in fruits and veggies at dinner. Cooking chicken or steak on the grill? Cut the meat into chunks and thread on a skewer for kabobs with cherry tomatoes, mushrooms, squash, pineapple, bell pepper and more. Or pour your spaghetti sauce over spiralized veggies. Don’t have a spiralizer or want to go to the trouble? No problem. You can buy frozen spiralized zucchini and carrots that cook in the microwave in minutes.
August: Sneak in fruits and veggies at snacks. Dip tortilla chips, sliced carrots or cucumbers in a vegetable-based dip like guacamole, salsa or hummus. Or instead of a package of nuts, make your own snack bags with nuts plus raisins or dried cranberries.
September: Add fruits and veggies when dining out. Produce is not always front and center on restaurant menus. Whether it’s a casual cafe, ritzy restaurant or the fast food drive-through, you can find options to add to your meal. Add a side salad to your meal if that’s a choice. Also, peruse the sides on the menu and select a green or yellow veggie to go with your entree. Finally, look for a dessert with fruit as an ingredient or ask for a fruit plate if it’s not on the menu.
October: Boost the taste appeal of fall produce. Fall brings an array of delicious vegetables like Brussels sprouts, acorn and butternut squash, turnips and carrots. To truly bring out their natural sweetness and flavor, try roasting them in the oven. This recipe for Pan Roasted Root Vegetables can be used with other veggies, too.
November: Add fruits and veggies to beverages. Bored with plain old water? Jazz it up a bit by making a juice spritzer with half juice and half sparkling water. For a more substantial snack or a quick breakfast on-the-go, whip up a smoothie with yogurt, banana, frozen mango and orange juice. And for holiday drinks, try a Cranberry Sour or Holiday Rosé.
December: Boost fruits and veggies in holiday meals. From appetizers like Mini Quiches to Apple Cranberry Stuffing, Mandarins & Beet Holiday Salad, Herb-Topped Beef with Roasted Cauliflower and Apple Pie, there’s not an item on the menu that can’t include fruits and veggies!
Remember that life is a marathon, not a sprint. Change takes time and so do results. By taking small, simple steps each month, you’ll be sure to have a happy, healthy 2021!

Even with anxiety and stress already high due to the current COVID-19 pandemic, the Environmental Working Group (EWG) still found it necessary to release its annual Dirty Dozen list yesterday. It lists the 12 fruits vegetables that allegedly have the highest levels of pesticide residues. But it’s actually just a thinly veiled attempt to create fear of conventionally grown produce and steer folks to buying expensive, organic produce. NEWS FLASH: organic farmers can and do use pesticides, natural and approved synthetic ones. FACT: pesticide residues on all produce – organic and conventional - are very low, if measurable at all.
Yesterday’s new list was identical to last year’s, same foods in the same order. While coronavirus news garners the lion’s share of headlines today, I did find a few inflammatory Dirty Dozen headlines on the second and third page of a Google search, “Strawberries Top the EWG's 2020 Dirty Dozen List” and “These 12 Foods Are Most Likely to Carry Pesticide Residue.” This one was actually a bit surprising: “Here are the ‘dirty dozen’ fruit and vegetables laced with legal pesticides — even organics have traces.” Key words here are “traces” and “organics.” So let’s take a closer look beyond the sensational headlines for a few things you need to keep in mind.
First, pesticide residues on conventionally grown produce are tested annually by the United States Department of Agriculture (USDA), with the results published in their Pesticide Data Program Annual Summary. In the most recent 2018 report, USDA found that “more than 99% of the samples tested had pesticide residues well below benchmark levels established by the Environmental Protection Agency (EPA). The EPA sets these benchmarks to ensure that pesticide residues remain at levels that EPA has determined to be safe in or on foods for human consumption.” And 48% of the samples tested had no detectable pesticide residue at all.
Second, as I previously mentioned and contrary to popular belief, organic farmers do use pesticides. Many are natural pesticides (but still kill insects and weeds) like sulfur, bicarbonate, copper and vinegar but also include synthetic pesticides approved for organic use. While organic produce is not regularly tested for pesticide residues, in 2010 the National Organic Program worked with the USDA to evaluate pesticide residues on 571 domestic and foreign fruit and vegetable samples bearing the USDA organic seal. The report revealed that 96% of the samples tested met the USDA organic regulations, with 57% showing no detectable residues and 39% with residues less than 5% of the EPA allowable level.
The fact is you have nothing to fear from eating any type of produce. All pesticide residues on fruits and vegetables, whether organically or conventionally grown, are extremely low and well below any level that could put you at risk. And according to University of California Berkeley Emeritus Professor of Biochemistry and Molecular Biology, Dr. Bruce Ames, 99.99% of the pesticides we eat are naturally present in plants to ward off insects and other predators. That means only 0.01% of ingested pesticides are synthetic.
So how does the Environmental Working Group come up with the data in its report that leads consumers to assume their produce is laden with pesticide residues? Believe it or not, they use the data in the USDA report mentioned above! Unfortunately, they misrepresent the data. How? They rank the fruits and vegetables in order of the pesticide residues found, from the highest to lowest amounts. Then they label the top twelve as “The Dirty Dozen.” But, as I explained earlier, the residue levels are extremely low and 99% of the samples tested fell well below the tolerance levels and 48% had no detectable pesticide residues. And two PhD toxicologists debunked the methodology the EWG uses to create this list in their research article in the Journal of Toxicology.
To put the EWG’s method into perspective, consider this comparison to National Merit Scholars. Most of us know these are very smart high school students who scored highly on the qualifying PSAT/NMSQT exam. So, imagine taking the list of National Merit Scholars for this year and ranking them according to their exam scores from highest to lowest and then taking the bottom twelve and calling them “The Dumbest Dozen.”
If you look deep into the EWG website you’ll find this disclaimer, “The health benefits of a diet rich in fruits and vegetables outweigh the risks of pesticide exposure. Eating conventionally grown produce is far better than skipping fruits and vegetables.” Of course, this statement never makes it into the articles with the sensational headlines. The EWG is not a research or academic institution with independent scientists. It is an activist group with some funding from the organic industry. In a survey of the scientist members of the Society of Toxicology, 79% say EWG overstates the health risk of chemicals.
According to a 2019 survey from the Alliance for Food and Farming (AFF), there was almost unanimous agreement among registered dietitians that it is important for consumers to know that conventionally grown produce is safe because not all people can afford to buy organic. They also believe that inaccurate, fear-based messages cause consumers to question whether eating conventionally-grown fruits and vegetables is safe.
Want to find out how many servings of a particular fruit or vegetable you could eat and still not have any adverse effects from pesticide residues? Check out the Pesticide Residue Calculator on the Safe Fruits and Veggies website. It turns out an adult woman would have to eat 453 servings of strawberries, 773 servings of spinach, 3,344 servings of organic lettuce or 4159 servings of conventional lettuce in one day without any effect, even if they had the highest pesticide residues level ever recorded by USDA for these foods.
If you’re still concerned, keep in mind that you should always wash your fruits and vegetables. Produce is grown in fields with soil. Many hands touch the produce from the time it leaves the field until it gets into your kitchen. From farmworkers to produce packers to supermarket employees to other customers, many bacteria-laden hands have landed on your fruits and veggies. While the main reason to wash it is to get rid of dirt and bacteria, it can also eliminate any tiny amounts of pesticide residues if they are even present.
Over 90% of people in the U.S. don’t eat enough fruits and vegetables so we should not be doing anything to discourage folks from enjoying any type of produce they like to eat, whether it is conventional, organic, fresh, frozen, canned, dried or juice. They all count toward your daily recommended fruit and veggie intake, are nutrient-rich and make you look and feel good. So, relax and enjoy the taste and fun of filling half your plate with fruits and vegetables. And for more information about fruits and vegetables and delicious ways to enjoy them, check out the Produce for Better Health Have A Plant website.
Growing up, orange juice was a staple on our breakfast table. And juice has continued to be part of my morning routine ever since. A 6-oz. glass of OJ supplies 100% of the daily recommended intake for vitamin C along with an array of other nutrients, all for just 80 calories. And it’s a quick and easy way to consume at least a third of your daily quota of fruit.
So imagine my surprise – and chagrin – when I learned that parents are being warned against serving fruit juice to their kids based on claims that juice is loaded with sugar and causes childhood obesity. A recent Wall Street Journal article actually characterized juice as a “gateway drink” to sodas and other sugar-sweetened beverages. Whoa! Are we seriously comparing fruit juice to a drug?? That’s definitely going too far in my book and sadly misjudges juice and its positive contributions to kids’ – and everyone’s – nutrient intake.
As a result of the negative press, many parents are forgoing juice altogether or diluting it with water. And some enterprising companies have jumped on the bandwagon by selling watered-down juice at a premium price. Just remember, this dilutes the nutritional contributions of juice by 50% as well. And it seems ironic that while parents are depriving their kids of juice, they’re drinking more of it themselves! The last decade has brought a boon in the sale of home juicers and a rise in juice and smoothie bars.
But no one is saying the fruit from which juice is made contributes to negative outcomes. As one of the 16 volunteer Produce for Better Health Foundation Fruit and Vegetable Ambassadors, we promote all five forms of produce: fresh, frozen, canned, dried and juice. So let’s explore more about the positive attributes of juice and dispel some myths.
Fruit Juice is Not Soda
In the past three decades fruit juice has gone from a perfectly acceptable breakfast beverage to one lumped in the same category as sugar-sweetened beverages like soda. A recent study based on self-reported sugary drink consumption, grouped soda and fruit-flavored drinks together with 100% fruit juice (but not sweetened tea) and concluded that they caused an increase in deaths. This analysis had several shortcomings, some acknowledged by the researchers: the number of participants who died during the relatively short follow-up period was small; the causes of death were not identified; soda consumption was self-reported, which is often underreported; results were based on 12-ounce portions, which is larger than usual for juice; and they did not estimate intake of all types of sugar-sweetened beverages, including sweetened tea.
While sugar content of soda and 100% juice may be similar, the comparison stops there. Fruit juice is a source of essential nutrients while sugar-sweetened beverages such as soda or fruit-flavored drinks provide no other nutrients besides sugar. And, according to a new study, there is no evidence to support claims that fruit juice consumption is linked to childhood weight gain or metabolic effects. Another recent study found similar results: children who drank more milk, 100% juice and water and less soda had better quality diets and giving up juice was not linked with lower body weights.
Fruit Juice is Nutrition-Packed
Juice is an easy way for children to obtain one or two fruit servings each day along with the key nutrients it contains. Juice delivers vitamins, minerals and phytonutrients important for good health including vitamins A, C and folic acid along with the minerals magnesium and potassium. In addition, those who drink fruit juice have a more nutrient-rich diet overall as well as a lower intake of added sugars, saturated fat and sodium. Juice is also a great way to help meet daily fluid needs and stay hydrated. But recommendations to limit juice can have unintended nutritional consequences. As people have consumed less fruit juice over the last 30 years, they have not replaced it with more whole fruit, so children and adults may not meet their daily recommendation for fruit intake.
Consider Juice as Part of the Total Diet
When you only look at individual foods or beverages in your daily meals, you may fail to see the big picture of how all foods and beverages work together to create a nutritionally adequate intake and influence your weight and health. Juice is only one component of your diet, so to claim that juice leads to obesity or other problems is misleading. There are many contributing factors and no single food or ingredient is responsible for negative effects. Simple “one-size-fits-all” solutions are not the answer. Including both 100% juice and whole fruit with meals and snacks is the best way to meet the daily recommended servings of fruit. How much do we need to eat? For children 1 – 6 years old, a total of 1 cup of fruit and juice each day is recommended and for those 7 – 12, 1½ cups should be consumed. Anyone 13 or older needs 2 cups of fruit over the course of the day, including juice.
With 75% of Americans not consuming enough fruit, we should not be doing anything to discourage folks from eating any kind of fruit. That’s why the 2015-2020 Dietary Guidelines for Americans recommend increasing fruit in all forms, including 100% juice. According to the Guidelines, one cup of 100% fruit juice counts as 1 cup of fruit. And while they recommend at least half of the recommended amount of fruits be whole fruit (fresh, frozen, canned or dried), that means up to half of daily fruit intake may come from 100% juice.
So stop worrying…and put juice back in your shopping cart and on your table for the entire family!

This blog was written in a paid partnership with the American Frozen Food Institute. However, the opinions expressed represent my personal views on food safety, nutrition and healthy eating.
Before the proverbial ink was dry on my listeria and lettuce blog, yet another scary headline emerged that appeared to question the safety of eating frozen produce. I am beginning to think there is a conspiracy in the media to discourage people from eating fruits and vegetables. And as a registered dietitian this is disappointing as my colleagues and I are doing everything we can to encourage folks to eat more produce. That’s because only one in 10 people in the U.S. consumes the recommended daily servings of fruits and veggies. Packed with nutrition, I promote all forms of fruits and vegetables to make it easy for people to eat more: fresh, frozen, canned, dried and juice.
First, let me share all the reasons I love frozen fruit.
Frozen food manufacturers are very diligent in making sure fruit is safely processed and packaged to prevent foodborne illnesses. Frozen fruit is thoroughly cleaned, washed and flash frozen within hours of being harvested. Once frozen, no bacteria can grow but, contrary to popular belief, freezing does not kill bacteria or viruses. That’s why so much care is taken to clean the fruit well before it is frozen, just like we wash fresh fruit at home that is purchased at a supermarket or farmers’ market.
So back to the scary headlines. Last week the Washington Post reported on a new U.S. Food and Drug Administration (FDA) program that is testing frozen berries for hepatitis A virus and norovirus. According to the FDA website, in 2019 and 2020, the agency will collect and test samples of U.S. grown and imported frozen packaged strawberries, raspberries and blackberries from processors, distribution centers, warehouses and supermarkets. If they find hepatitis A virus or norovirus, FDA will notify and work with the company to take action to protect the public health, such as issuing public warnings or instituting a product recall. (1) The Post article stated that since the inspections began in May, FDA has recalled one brand of a frozen blackberry product and one of a blended berry product that were found to contain parts of the hepatitis A virus. While the FDA advised consumers not to eat and to throw away the specific berry products identified, they noted that no cases of hepatitis A had been linked to them. (2)
Why would berries contain viruses or bacteria? They may become contaminated if handled by an infected worker who does not wash his or her hands properly or if the berries are exposed to a contaminated surface or agricultural water. As I mentioned earlier, bacteria, viruses and microorganisms can survive at low temperatures, including freezing. That’s why the industry is so diligent in its food safety practices.
Foodborne illness is a serious issue so we are very fortunate in the U.S. to have government agencies like the FDA, U.S. Department of Agriculture (USDA) and the Centers for Disease Control and Prevention (CDC) who are vigilant in setting standards and monitoring the safety of our food so that we have the safest food supply in the world.
The Post article also quotes Dr. Donald W. Schaffner a food science professor at Rutgers University who states that FDA tests for the DNA of the two viruses and the recall do not mean the berries contained the whole, live hepatitis A virus that causes illness. He goes on to say that he is not changing his berry eating habits as a result of this report because they are “safe, healthy foods” and “We want people to eat more fruit and vegetables.”
And the Academy of Nutrition and Dietetics agrees. An article on their website by registered dietitian nutritionist Esther Ellis says, "Frozen foods are an affordable way to get your daily dose of fruits and vegetables. In fact, families who incorporate frozen foods into their normal routine may have better diet quality.”
Those who follow my blog and social media know I’m passionate about promoting fact-based food and nutrition information to help people “eat beyond the headlines” and enjoy a variety of nutrient-rich foods. Most of the time those scary headlines are a result of a study misrepresented and sensationalized in the media or an activist group with an agenda fostering fear about perfectly safe foods or ingredients. But the headlines that appeared in the news this past week evoke fear of food for a different reason and that’s food safety.
The latest headlines are a result of a Consumer Reports investigation of 284 samples of bagged and loose lettuce and other leafy greens from supermarkets that found six (2%) contained listeria. Listeria monocytogenes is a bacteria that causes the foodborne illness listeriosis especially in high-income, industrialized countries. It is widespread in the environment. According to the U.S. Food and Drug Administration (FDA), compared to other foodborne illnesses, listeriosis is rare but very serious. Healthy children and adults occasionally get listeriosis, but seldom become seriously ill. People with weakened immune systems, pregnant women and the elderly, however, are at greater risk of a more severe form of listeriosis. (1) The report quotes the Centers for Disease Control and Prevention’s (CDC) medical officer, Karen Wong, M.D., as saying, “It is rare for healthy adults to get sick with listeria infection.”
SPOILER ALERT: This report does NOT advise people to stop eating lettuce and leafy greens. Nor does the report mean that leafy greens are riskier than any other foods – despite the scary headline. In fact, the report notes that listeria is usually associated with deli meats, hot dogs, soft cheeses and sprouts. They also state that the “study represents a snapshot of the market and was not large enough to draw conclusions about the safety of specific brands or retailers.” Keep reading for more context.
Food Safety Facts
Listeria is commonly found in many food items, not just leafy greens. If you check the FDA’s website you will see that several were involved in recent recalls due the detection of listeria. These included egg, tuna and lobster products in addition to other vegetables like squash and cauliflower.
We are fortunate in the U.S. to have the safest food supply in the world. Our government and its agencies like the U.S. Department of Agriculture (USDA), Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) have regulations and programs that ensure those who grow, process and distribute our food are following high standards of safety and sanitation. There are other voluntary organizations that set additional standards and conduct testing of foods and farms to further ensure safety. But no system is perfect and at times we do have outbreaks that compromise the safety of a food for a short period of time. But, again, the government and its departments are quick to evaluate the situation and make sure the offending products are removed from our food supply until the problem is resolved.
As registered dietitians, my colleagues and I are concerned that most folks in our country are not eating enough fruits and vegetables. In fact, only 1 in 10 people consume the recommended amount of produce each day. A just-published study in Critical Reviews in Food Science and Nutrition reviewed nearly 100 studies that looked at the effects of fruits and vegetables on a variety of diseases. Their findings: eating at least five servings of fruits and vegetables every day can drastically reduce the risk of heart disease, protect us from certain forms of cancer and promote eye and bone health, among other benefits. (2)
So anything that prevents people from eating fruits and vegetables is a concern for me, whether it’s from scary headlines that promote misinformation or real food safety issues. Putting these headlines in perspective is among the roles I play as a nutrition communications specialist. To this end, I have partnered with two organizations to further my efforts. First, I’m one of 16 volunteer Fruit and Vegetable Ambassadors in Action selected by the Produce for Better Health Foundation. Our role is to encourage increased intake of fruits and vegetables, not only for their many health benefits but also because they help you look good, feel good and have more energy. I am also a consultant with the Leafy Greens Marketing Agreement (LGMA), to help spread the word about the safety and nutritional value of leafy greens. LGMA is a program that verifies compliance with the food safety practices of leafy green growers through mandatory government audits.
Putting it in Perspective
How often does food contaminated with listeria actually result in an illness? The number of foodborne illnesses is extremely small compared to the vast amount of food eaten in the U.S. And when it comes to leafy greens, the chance of becoming ill is much, much less than the risk of dying in a plane crash or being struck by lightning. Yet 1 in 4 people die of heart disease every year in the U.S. (3) And that is a statistic we know can be dramatically improved by eating more fruits and vegetables, including leafy greens like lettuce and spinach.
Consumer Reports focused only on lettuce and leafy greens in this new report. Because leafy greens are packed and most often eaten raw, it is not overly surprising that that 2% of the samples tested contained listeria. They did not test other food products or even fresh vegetables to see if they had a similar small number with listeria. And they did not find other bacteria that cause foodborne illness, such as salmonella and E. coli in these 284 samples.
In reality, Consumer Reports’ findings are in line with previous ones conducted by U.S. government agencies. A study published in 2017 found listeria monocytogenes in just over one percent of 1,700 raw cut vegetable samples tested from 2010-2013 by USDA and FDA scientists. And this is similar to previously published research, which the fresh produce industry relies on to stay informed and in front of food safety concerns that could affect consumers.
The Bottom Line
This report does NOT mean leafy greens are riskier than any other foods. And, in my professional opinion, greens deliver much greater health benefits than health risks. I am not, however, suggesting that we should ignore health warnings related to foodborne illness. We certainly should, especially when a government agency issues a recall or consumer advisory, which they have not done so far in this case..
People in vulnerable groups – those with weakened immune systems, the elderly and pregnant women - may want to take additional precautions such as these mentioned in the Consumer Reports article:
Fortunately leafy greens like kale and spinach are delicious and just as nutritious when they are cooked as when eaten raw.
The CDC also provides additional suggestions for preventing illness from listeria due to other foods on their website.
A dietitian friend recently told me a story about one of her nutrition counseling clients. When discussing fruits and vegetables, he told her he only ate organic produce. When she asked why, he replied, “Honestly, I just don’t want to have to wash my produce.” He thought the only reason to wash fruits and vegetables was to remove pesticide residues and he assumed that organic would have none.
Much of the fear of pesticide residues on non-organic produce is driven by the Environmental Working Group’s (EWG) annual Dirty Dozen list. This list garners headlines like, “Kale Is One of the Dirtiest Vegetables” and “Are You Eating Pesticide-Laden Produce?” It is a thinly veiled attempt to scare hard-working, cash strapped Americans away from buying conventional fruits and vegetables and instead choosing higher-priced, organic produce. Taking a closer look beyond the sensational headlines, there are a few things you need to keep in mind.
First, the main reason to wash fruits and vegetables is to get rid of dirt and bacteria. Produce is grown in fields with soil. Also, just think of the number of hands that have touched your produce from the time it leaves the field until it gets into your kitchen. From farmworkers to produce packers to supermarket employees to other customers, many bacteria laden hands have landed on your fruits and veggies.
Second, pesticide residues on conventionally grown produce are tested annually by the United States Department of Agriculture (USDA), with the results published in their Pesticide Data Program Annual Summary. In the most recent 2017 report, USDA found that over 99% of the samples tested had residues well below the tolerances established by the Environmental Protection Agency and, of these, 53% had no detectable pesticide residue at all.
And third, contrary to popular belief, organic farmers do use pesticides. Many are natural pesticides (but still kill bugs and weeds) like sulfur, bicarbonate, copper and vinegar but also include synthetic pesticides approved for organic use. While organic produce is not regularly tested for pesticide residues, in 2010 the National Organic Program worked with the USDA to evaluate pesticide residues on 571 domestic and foreign fruit and vegetable samples bearing the USDA organic seal. The report revealed that 96% of the samples tested met the USDA organic regulations, with 57% showing no detectable residues and 39% with residues less than 5% of the EPA allowable level.
The fact is you have nothing to fear from eating any type of produce. All pesticide residues on fruits and vegetables, whether organically or conventionally grown, are extremely low and well below any level that could put you at risk. The December 2018 news release from the USDA for their most recent report was headlined, “USDA Releases 2017 Annual Pesticide Data Program Summary, U.S. Food Supply is Among the Safest in the World.”
And according to University of California Berkeley Emeritus Professor of Biochemistry and Molecular Biology, Dr. Bruce Ames, 99.99% of the pesticides we eat are naturally present in plants to ward off insects and other predators. That means only 0.01% of ingested pesticides are synthetic.
So how does the Environmental Working Group come up with the data in its report that leads consumers to assume their produce is laden with pesticide residues? Believe it or not, they use the data in the USDA report mentioned above! Unfortunately, they misrepresent the data. How? They rank the fruits and vegetables in order of the pesticide residues found, from the highest to lowest amounts. Then they label the top twelve as “The Dirty Dozen.” But, as I explained earlier, the residue levels are extremely low and 99% of the samples tested fell well below the tolerance levels and 53% had no detectable pesticide residues. And not one but two PhD toxicologists have debunked the methodology used by the EWG to create this list in their research article in the Journal of Toxicology.
To put the EWG’s method into perspective, consider this comparison to National Merit Scholars. Most of us know these are very smart high school students who scored highly on the qualifying PSAT/NMSQT exam. So, imagine taking the list of National Merit Scholars for this year and ranking them according to their exam scores from highest to lowest and then taking the bottom twelve and calling them “The Dumbest Dozen.”
If you look deep into the EWG website you’ll find this disclaimer hidden in the Q&A section, “The health benefits of a diet rich in fruits and vegetables outweigh the risks of pesticide exposure. Eating conventionally grown produce is far better than skipping fruits and vegetables.” Of course, this statement never makes it into the articles with the sensational headlines. The EWG is not a research or academic institution with independent scientists. It is an activist group with some funding from the organic industry.

Want to find out how many servings of a particular fruit or vegetable you could eat and still not have any adverse effects from pesticide residues? Check out the Pesticide Residue Calculator on the Safe Fruits and Veggies website. It turns out an adult woman would have to eat 13,204 servings of blueberries or 4,159 servings of conventional lettuce or 3,344 servings of organic lettuce in one day without any effect, even if these had the highest pesticide residues level ever recorded by USDA for blueberries or lettuce. For more information about fruits and vegetables and delicious ways to enjoy them, check out the Produce for Better Health Have A Plant website.
Over 90% of people in the U.S. don’t eat enough fruits and vegetables so we should not be doing anything to discourage folks from enjoying any type of produce they like to eat, whether it is conventional, organic, fresh, frozen, canned, dried or juice. They all count toward your daily recommended fruit and veggie intake, are nutrient-rich and make you look and feel good. So, relax and enjoy the taste and fun of filling half your plate with fruits and vegetables.
When I was growing up canned foods were a staple in our kitchen pantry and our meals. From canned green beans and corn as a dinner side dish to salads with canned peach or pear halves topped with a scoop of cottage cheese or canned asparagus and tomato aspic on a lettuce leaf topped with a dollop of Miracle Whip, canned foods were an essential part of my life. And the can-filled meals continued with my mom’s Friday dinner rotation featuring tuna noodle casserole created with canned tuna, cream of mushroom soup and peas and her spaghetti and lasagna with canned tomatoes as a key ingredient. Back then, canned foods were normal, not berated or relegated to second-class status as they are frequently characterized today. It’s sad because canned foods boast an array of benefits that often go unrecognized. So what better time to extol the virtues of canned foods than February, National Canned Food Month.
Canned foods can…
Boost nutrition: Packed within five hours of harvest, canned fruits and vegetables are at their peak of ripeness, flavor and nutrient content. Without any oxygen in the can, their abundant supply of vitamins and minerals are locked in at their original amounts until they are opened and eaten. Studies actually show that canned foods provide as much – and sometimes even more - nutritional value as fresh ones do. This makes sense when you consider that it often takes over three weeks for fresh produce to get from the farm to the supermarket while canned and frozen ones are packed within hours of picking. Research further documents that people who eat more canned food consume more nutrient-rich foods like fruits, vegetables, dairy and other protein foods compared to infrequent canned food users. They also have a higher intake of 17 essential nutrients including the shortfall nutrients identified in the Dietary Guidelines for Americans — potassium, calcium and fiber.
Save money: Canned foods are a bargain both nutritionally and for your wallet! According to a 2014 study published in the American Journal of Lifestyle Medicine, USDA Economic Research Service data revealed that canned vegetables may provide a cost savings of up to 20% over fresh and have a longer shelf life.
Make meals in minutes: Already cooked, canned foods help you create meals in a flash. Canned fruits, veggies, beans and meat can serve as an ingredient in salads, sandwiches, soups, stews and casseroles. Canned vegetables are a great side, canned beans a savory main dish and canned fruit an easy dessert alone or added to yogurt or ice cream. The Cans Get You Cooking website boasts an assortment of recipes and videos to get you started. In addition, the Canned Food Alliance has recipes and an Essential Kitchen Toolkit to help you organize and stock your kitchen and plan and prepare meals.
Reduce food waste: Half of all fresh produce in the U.S. is thrown away. Produce is lost in fields, warehouses, packaging, supermarkets, restaurants and at home. In fact, most Americans throw away about 15 - 20% of the fresh fruits and vegetables they purchase every year. Foods in landfills produce methane, a greenhouse gas associated with climate change. On the other hand, the peels, cores and other inedible parts of fruits and vegetables removed during the canning process are re-used as feed for farm animals or composted. Very little is wasted. Canned foods are non-perishable and have a long shelf-life, at least two years from the date of purchase when stored in moderate temperatures of 75° F. or less. That further decreases food waste. And the cans themselves can be recycled, also lessening environmental impact.
Canned foods are not….
Highly processed: Canned foods are actually very minimally processed. After food is packed into sealed, airtight cans, heat is applied to kill microorganisms. Then the cans are heated under steam pressure at 240-250° F. for the minimum time it takes to ensure they are sterile but still retain optimum flavor and nutrition. No preservatives are added or necessary. So canned foods frequently sport some of the “cleanest” labels around. A quick look in my pantry reveals salsa style canned tomatoes with tomatoes, tomato puree, jalapeno peppers, Anaheim peppers, salt, dehydrated onion, citric acid, spices, acetic acid (vinegar), dehydrated garlic, calcium chloride; and canned pears with pears, water, pear juice from concentrate and canned Alaskan salmon with pink salmon and salt.
High in salt and sugar: Only 11% of sodium in the diet comes from vegetables, including canned forms. And just 2% of added sugar in the diet comes from fruits and vegetables, including canned ones. For those who need to reduce salt, low sodium and salt-free canned foods are readily available. Research has demonstrated that simply draining and rinsing regular canned vegetables can reduce sodium by 41% while draining alone lowers it by 36%. Less canned fruit is now packed in heavy syrup as compared to light syrup, 100% juice and no-added sugar varieties.
Lower quality than fresh: Some have the mistaken belief that canned foods are the “seconds” or lower grade than those that are sent to the fresh market. I was on a canned fruit and vegetable harvest tour in September 2017 and learned this is not true at all. The peach orchard and tomato farm we visited were grown exclusively for the cannery down the road. We literally followed the freshly-harvested produce down the road to the canning facility and watched as it was unloaded and transported through the canning process. As I mentioned earlier, these canned fruits and veggies go from field to can in less than five hours.
Unsafe due to protective linings: Can linings actually ensure the safety, quality and nutritional value of the food inside. Years of testing is conducted prior to approval of any coatings used in can linings. One coating, bisphenol A (BPA) has come under fire in recent years as a result of preliminary studies written about in the popular media. However, the U.S. Food and Drug Administration along with safety agencies around the globe continue to affirm its safety based on a vast body of research. FDA states on its website, “People are exposed to low levels of BPA because, like many packaging components, very small amounts of BPA may migrate from the food packaging into foods or beverages. Studies pursued by FDA's National Center for Toxicological Research have found no effects of BPA from low-dose exposure.” But due to consumer concerns about BPA many companies are using or transitioning to new can coatings without BPA.
Putting it all together
Canned foods can go back in your shopping cart and pantry and on your menu and plate. They’re nutritious, delicious, safe, convenient, non-perishable and economical. So next time you’re in the supermarket, take a stroll down the canned food aisles and stock up on some of the 1500 varieties of always-in-season, canned foods available year-round.
I’m not a beer drinker. But if I was, the Super Bowl commercial that would have tempted me to try their brand was definitely Stella Artois. At an upscale restaurant, waiters collide and drop trays as Carrie Bradshaw and The Dude forgo their traditional Cosmopolitan and White Russian for a Stella or “Stella Ar-toes” as The Dude called it. During the scene where a glass of Stella is drawn from the tap and the head leveled off with a knife, I could almost taste and smell the beer.
Fast forward to another beer commercial, this time from Bud Light. Instead of touting their product for its taste, quality and fun they chose to resort to the newest marketing tool of the food and beverage industry, fear. In a medieval scene, Bud Light brewers mistakenly receive a barrel of corn syrup for their beer. So they harness up their horses to pull the corn syrup barrel first to Miller Lite brewers, who say they’ve already received their corn syrup delivery, and then to the Coors Light brewery that is happy to claim it. The last line of the ad assures us that Bud Lite is “brewed with no corn syrup.”
Does this really make any difference? Let’s review “Beermaking 101.”
The beer brewing process starts with grains, usually barley but also rye, corn, oats or wheat. What these all have in common is they are primarily composed of starch, a complex carbohydrate. Starch is made up of hundreds of glucose (a simple sugar) molecules bound together. After being heated and dried, the grains are immersed in hot water where the enzymes in the grains release the glucose from the starch and create a sugar syrup, which is the basic ingredient for making beer. Whether its barley syrup, rye syrup, corn syrup, oat syrup or wheat syrup, chemically it’s all the same – glucose (sugar) mixed with water. The body cannot tell the difference between glucose from any food or beverage source. It is identical. The only difference is each grain imparts a different flavor to the beer.
So why does the Bud Light commercial portray beer made with corn syrup in a negative light? It is most likely to play on consumers’ misplaced fears about high fructose corn syrup and/or GMO corn. As I mentioned earlier, corn syrup used in making beer is 100% glucose. High fructose corn syrup (HFCS) is a product created from corn syrup by converting some of the glucose into fructose so that it has about 50% each, the same as white sugar and honey. Created in the 1970’s, it replaced sugar as an ingredient in many foods and beverages because its sweetness was nearly identical to sugar but it was easier to use, more stable and functioned better in products.
But furor ensued in the 2000’s when some scientists suggested that the increase in HFCS intake might be the reason obesity in the U.S. was on the rise. There is no scientific evidence to support this and numerous studies have found no difference in the body’s use of sugar vs. HFCS nor any increased risk of negative health effects. And according to two different government surveys the intake of all sugars, including HFCS, has gone down since 1999 while obesity has continued to rise.
In addition, GMO corn is safe. There is no difference in nutrition, health or safety between GMO and non-GMO corn. GMOs are not “in your food.” Agricultural biotechnology, commonly called GMO, is a method of growing crops like organic or conventional farming. A single genetic trait from another plant is inserted in the DNA of the crop seed so it can resist a certain insect or weed killer, tolerate drought so it can grow with less water or increase the amount of a vitamin or other nutrient in a food. And if there is any slight genetic difference in the corn itself, it would not show up in corn syrup. That’s because DNA is always combined with protein and there is no protein in corn syrup. It is 100% carbohydrate in the form of sugar.
So what’s the bottom line when it comes to choosing beer? Make your decision as you would with any food or beverage on taste, cost, quality and enjoyment. Or support your local brewery like Coors if you live in Colorado or Shiner if you’re in Texas. Don’t base it on negative marketing and misleading claims of fear.
A new report surfaced last week in a noted British medical journal, The Lancet, that recommends a near-vegan eating style as a way to promote greater sustainability of the food system, lessen the environmental impact of animal agriculture and improve health of the world’s population. Of course, this is the same journal that published a notorious study – later debunked and retracted – suggesting a link between the measles/mumps/rubella vaccine and autism, which ignited the current anti-vaccination movement.
Created by the EAT-Lancet Commission, a collaboration between the EAT Forum (founded through the Stordalen Foundation), the Stockholm Resilience Centre and the Wellcome Trust, the investigation and report were funded by EAT and the Wellcome Trust. The founder and chair of the Stordalen Foundation is a billionaire Norwegian physician who is a vegan. The co-chair of the EAT-Lancet Commission and lead author of the report is a Harvard professor well-known for his strong stance against meat in the diet. But he’s not a fan of potatoes, either. Wait, aren’t they plants?
Reading beyond the headlines hailing this report, is it really advisable for everyone to adopt a near-vegan eating pattern? Before we call on governments and health agencies around the world to endorse such a radical change in traditional food production and consumption, we need to explore the societal, environmental and nutritional implications of doing so.
Is a near-vegan diet more sustainable?
As technology has transformed our world over the past century, people have become more concerned about its impact on the environment. Like most other industries, agriculture has embraced technology to help farmers produce food more efficiently. And this is a good thing when you consider that 40% of the labor force in the U.S. was engaged in farming 100 years ago while only 2% is today. That means farmers must produce more food for a population that has tripled from 104.5 million in 1919 to 326.8 million today while the amount of farm land and water has remained the same or been reduced. And they have been very successful in doing that.
According to the Environmental Protection Agency, U.S. agriculture accounts for around 9% of total U.S. greenhouse gas emissions compared to 28% for electricity, 28% for transportation and 22% for industry. And a 2017 study revealed that removing all animals from the food supply and replacing all of those calories with plant crops would only reduce total U.S. greenhouse gas emissions by 2.6%.
Farmers from all sectors of the industry are working toward sustainability in their practices to protect and enhance the land and conserve water and other resources so their farms can continue to produce food for future generations. And equally important, creating a sustainable farm allows them to make a living so they can stay in business so we’ll all have food to eat.
U.S. cattle ranchers are producing the same amount of beef today as they were 40 years ago with one-third fewer cattle. Likewise, through improved cow breeding and feeding, dairy farmers produce milk today with 90% less land and 65% less water than in the mid-20th century, resulting in a 63% smaller carbon footprint. In 1950, there were 25 million dairy cows but only 9 million today while milk production has increased by 60%.
And in the egg industry, innovations in nutrition and breeding since 1960 have increased egg production by 27% while decreasing daily hen feed by 26%, water use per dozen eggs produced by 32% and hen death by 57% while lowering greenhouse gas emissions by 63%.
Finally, half of all fertilizers used in the U.S. to grow fruit, vegetables and grains are organic fertilizers made from livestock manure. Eliminating animal agriculture would mean replacing them with chemical fertilizers that are very energy intensive to produce.
Will a near-vegan diet feed the world?
In the U.S. only 1 in 10 adults currently eats the minimum number of fruits or vegetables recommended in federal dietary guidelines according to a Centers for Disease Control and Prevention study. Dietitians are continually challenged to help people find ways to enjoy eating more of these nutrient-rich foods.
Will eliminating most of the meat, eggs and dairy foods from the food supply force folks to eat more of these wholesome plant foods? The even bigger question: is there enough land to grow the amount of produce and grains we would need to replace the calories and other nutrients provided by animal foods? Will eliminating livestock grazing free up more land to produce more food for people to eat?
According to the World Bank, 37.2% of the world's total land area is considered agricultural but only 10.9% is arable or capable for growing crops like fruits, vegetables and grains. That’s less than a third of the total agricultural land. The other 70% of agricultural land is marginal and not suitable for growing crops due to lack of water and/or poor soil quality. It is only good for grazing ruminant animals that can digest grass - goats, sheep and cows. In addition, 85% of cattle feed is not digestible by humans like grass, wheat and oat straw, sugar cane tops and corn silage (husks, leaves and stems). Thus, these ruminant animals convert food with poor-quality protein from plants inedible for humans into high-quality protein food with a variety of nutrients not always plentiful in plant-based foods.
Will a near-vegan diet adequately nourish the world?
I love fruits, veggies and grains. I eat a lot of them. But I also enjoy eating meat, dairy and eggs. I have friends who are vegans and vegetarians and I respect their right to choose that eating pattern and they respect mine to include animal foods in my diet. A vegan diet can be nutritionally adequate and promote health just like those including animal foods. Having said that, it is more challenging to meet these nutrient needs but it can be done with careful planning and some supplementation of vitamins only found in animal foods. The bigger question is whether we can nourish an entire population (country, continent or world) with only plant foods.
The previously mentioned 2017 study compared the current U.S. food production system to a modeled one where animal agriculture and animal-derived foods are eliminated. The plant-only agriculture system produced 23% more food but met fewer of the essential nutrient requirements for people in the U.S. The plant-only diets projected more nutrient deficiencies, a need to consume a greater amount of food and more calories. Researchers concluded that removing animal foods from the U.S. food supply resulted in diets that did not support people’s nutritional needs without nutrient supplementation.
Animal foods like meat, poultry, fish, eggs and dairy provide high-quality protein with all the essential amino acids in amounts necessary for building and maintaining all body tissues. In addition, each of these foods supplies additional nutrients that are not always present in significant amounts in plant-based foods.
On the other hand, fruits and vegetables contribute nutrients like vitamins A and C, folic acid, potassium, fiber and phytonutrients that are not provided by or are present in smaller amounts in animal foods. And grains are a source of fiber, several B vitamins along with iron, magnesium, and selenium.
That’s why a diet with a variety of foods from all groups helps ensure an adequate intake of all nutrients. Leaving out one or more groups makes it more difficult. For example, you would have to eat 1.25 cups cooked spinach (50 calories) or 3.75 oranges (335 calories) to get the same amount of calcium in a cup of 1% low-fat milk (100 calories). And it takes 3 cups of cooked quinoa (660 calories) or 1.7 cups of black beans (385 calories) to obtain the protein in 3 ounces of lean cooked beef (156 calories). In addition, some vegetables, grains, nuts and seeds contain oxalate and phytates that can bind minerals like calcium, iron and zinc and keep them from being absorbed. On the other hand, the lactose and vitamin D in milk enhance the absorption of calcium.
The U.S. Department of Agriculture’s MyPlate, the graphic representation of the U.S. Dietary Guidelines, is a plant-based eating pattern with three-quarters of the plate comprising fruits, vegetables and grains. Including animal foods in the diet can help boost intake of plant foods. One way to encourage people to eat more plant foods is to pair fruits, vegetables and grains with meat, eggs and dairy: yogurt and fruit, cheese and bread, beef/pork/chicken in a vegetable stir-fry with rice, a fish taco in a whole grain tortilla with chopped tomato and bell pepper or an omelet layered with vegetables and cheese.
Putting it all together
Sustainability is essential to protecting the environment and feeding and nourishing the world. In the U.S. farmers and ranchers have worked diligently to become more efficient in producing more food with fewer resources. This has significantly reduced the impact on land, water and chemical use. Unfortunately some other countries, especially developing ones, have not been as successful or even have the ability to harness technology to improve productivity. Rather than radical changes to the world’s food system, a better solution would be to direct resources to helping farmers throughout the world to work more efficiently and sustainably.
Because sustainability is also about sustaining health through sufficient food that delivers adequate nutrition as well as sustaining farmers’ abilities to maintain financial security in order to continue producing enough food, it cannot simply be viewed through the narrow lens of environmental impact. Food and meals are an integral part of our lives. People choose foods for many reasons, not just for nutrition and health but also for taste, cost, availability and cultural, religious and family traditions. Dietitians play a critical role in helping people adopt eating habits that not only ensure health but also accommodate these other factors. Finding appealing ways for individuals to consume more plant-based foods like fruits, vegetables, grains, nuts and legumes can boost nutrition and still be compatible with eating appropriate amounts of animal foods to obtain essential nutrients. Creating this balance will have long-term influences on enjoyment of eating, nutritional adequacy, health status and the environment of our planet.
