Updating the 2015 Dietary Guidelines for Americans

A Chance for Physicians to Comment in Favor of Sustainable, Science-Backed Solutions

As a nation, we’ve never been more confused about which food choices lead to optimal health. With the recent controversy surrounding cholesterol, it’s easy to see why. This is one reason I presented today at the Public Meeting for Oral Testimony on the Scientific Report of the 2015 Dietary Guidelines Committee at the National Institutes of Health.

The final 2015 Dietary Guidelines for Americans will come out later this year, but the public now has an opportunity to weigh in on the Dietary Guidelines Committee’s recommendations. The Dietary Guidelines have an extraordinary impact on food choices consumers will make and dietary habits our next generation will form. The guidelines manifest into meals purchased for our nation’s schools, senior centers, and hospitals, not to mention choices you’ll see readily available at the local corner market and grocery store.

We should be supporting sustainable, healthful foods that fall into these four food groups.

Unfortunately, these menus often fall short on painting the picture of perfect health. Instead, they still serve a surplus of fat, sodium, and cholesterol, which, despite recent headlines, is still a nutrient of concern. If we want to combat metabolic syndrome—the perfect storm of high blood pressure, high blood sugar, excess weight, and elevated cholesterol—we have to act now. Nearly 70 percent of Americans struggle with weight, a risk factor for many forms of chronic disease, including heart disease, type 2 diabetes, and certain forms of cancer. And half of Americans who maintain a healthy weight are still at risk for at least one metabolic risk factor.

While the expert report for the 2015 Dietary Guidelines for Americans is heading in the right direction with a focus on plant-based dietary patterns, it still needs some work. Especially when it comes to educating the public about the dangers of dietary cholesterol, the “necessity” of dairy products, and explaining the leading sources of saturated fat, in plain language: high-fat cheeses, meats, oils, and dairy products.

New Dietary Guidelines: The Good, the Bad, and the Downright Confusing

Today, the Dietary Guidelines Advisory Committee released its report on what Americans should eat. When finalized, the Guidelines will be the basis for all federal programs, including school lunches. And the report is a huge step forward in several ways:

  1. The report singled out vegetarian diets as one of three healthful diet patterns. The other two healthy patterns were the Mediterranean diet and the “Healthy U.S.-style Pattern.” Vegetarian diets reduce the risk of obesity, diabetes, and other health problems and have gained greater prominence in each new edition of the Guidelines.
  2. The report was a rebuke for those who have suggested that saturated (“bad”) fat, common in meat and dairy products, is somehow not a danger. The report emphasized saturated fat’s risks and maintained the previous limit that no more than 10% of calories should come from saturated fat.
  3. The report deleted “lean meat” from its list of favored foods. Its authors were convinced by evidence showing that increased consumption of “lean meat” confers no health benefits.
  4. The report breaks new ground in reporting on food’s relationship to environmental health, which in turn affects human health.

But for all its good points, the new report has trouble spots:

  1. The report suggested that cholesterol in foods is not a major danger, contrasting with the Institute of Medicine, which found that cholesterol in foods does indeed raise blood cholesterol levels, especially in people whose diets are modest in cholesterol to start with. On this topic, the Dietary Guidelines Advisory Committee did no original research and instead deferred to a 2014 report by the American Heart Association and American College of Cardiology. However, the American Heart Association receives substantial cash payments for certifying food products, including cholesterol-containing food products as “heart healthy,” creating a financial incentive for discounting the relationship between dietary cholesterol and serum cholesterol.

    The Physicians Committee is concerned that exonerating dietary cholesterol will only confuse an already bewildered public. Most people do not differentiate fat from cholesterol, or dietary cholesterol from blood cholesterol. To suggest that cholesterol in foods is not a problem will lead many to imagine that fatty foods or an elevated blood cholesterol level carry no risk—two potentially disastrous notions.

    Accordingly, the Physicians Committee has petitioned the USDA and DHHS to disregard the Dietary Guidelines Advisory Committee’s findings on dietary cholesterol. The reliance on the American Heart Association document does not comply with the spirit of the Federal Advisory Committee Act, which sets standards for bias among federal advisory committees.

  1. The Committee report recommends fish, despite frequent contamination with mercury and PCBs, and despite evidence that vegetarians who avoid fish and shellfish are slimmer and have less risk of diabetes, compared with people who eat fish.
  2. The report continued to recommend dairy products, despite recent evidence that they do not “build strong bones” or protect against fractures.

Even with its flaws, the new Dietary Guidelines report is a major advance.

The Physician Committee’s own recommendations, represented graphically in The Power Plate (www.ThePowerPlate.org), focus on whole grains, vegetables, fruits, and legumes as dietary staples. The Power Plate rests on hundreds of scientific studies showing that plant-based eating habits are associated with lower obesity rates and a reduced risk of heart disease, hypertension, and type 2 diabetes.

USDA “Beefing” Up Special Interest Marketing Funds

It's What's for Dinner

Remember the old “Beef. It’s What’s for Dinner” advertisements? Those were sponsored by the beef checkoff program.

Red meat production and sales have declined as the public has become increasingly aware of the link between meat consumption and chronic disease. For consumer health, this is progress. However, the USDA is now proposing a new “checkoff” program to allocate additional funds—potentially totaling $160 million—towards the promotion and marketing of beef in 2015. And since the USDA also issues national dietary recommendations, this creates a clear conflict of interest.

Beef is bad for your health. Physicians, researchers, and medical organizations clearly state the consequences of eating red meat. Harvard University has published numerous studies associating meat consumption with chronic disease. The World Health Organization notes the correlation between meat and colorectal and prostate cancers in its dietary recommendations. The American Heart Association published findings saying that women who had two servings per day of red meat had a 30 percent higher risk of developing coronary heart disease. Physicians Committee researchers found that eating meat is a risk factor for diabetesThe American Institute for Cancer Research recommends reducing and removing red and processed meat, as does the American Cancer Society. Even government officials in the United Kingdom have been clear in their recommendations to British citizens to cut red meat consumption.

However, the USDA has remained ambiguous when discussing red meat. In the 2010 Dietary Guidelines, the USDA recommended reducing saturated fat and cholesterol intake—neglecting to mention that a sirloin steak overloads your arteries with 155 percent of your daily maximum intake of saturated fat and 152 percent of your daily maximum cholesterol.

The USDA is accepting public comments on the proposed checkoff program until Dec. 10. Click here to take action by submitting your comments to the USDA.
