The federal government has issued dietary guidelines every 5 years since 1980. They are the ones that came out with the food pyramid, and most recently gave limits for sugar, saturated fat, and sodium (salt). These guidelines affect many things, including what children get served for lunch at school.
For the first time ever, the Department of Health and Human Services and the Department of Agriculture, under the direction of the Trump administration, is limiting the scope of the committee. They gave them a list of 80 questions, and said they are not to consider anything outside that list. Those questions do not include health risks such as too much salt, red meat, and processed foods.
The nature of science is that with ongoing research things change. Most of you can probably recall getting conflicting diet recommendations over the years. We were told to avoid fats, as we subsequently got collectively heavier, then ketogenic diets said the opposite. Alcohol can decrease heart disease, then studies showed it can increase breast cancer. That’s why it’s important to periodically review the literature and adjust recommendations if warranted.
Why would the Trump administration want to limit the committee? For one thing, they have generally been anti-science in many areas, such as global warming. For another, as they say, follow the money. Thirteen out of 20 of the committee members have food industry ties. This compares with two of 12 members in 2015. You can read more details in a Washington Post article.
Health care costs have been going up at a rate higher than inflation for many years. Although there are many reasons for this, part of it is because people are getting more obese. This leads to such health issues as diabetes, hypertension, heart disease, and arthritis. The new rules effectively says that corporate interests trump human health. So that corporations can profit more, we will pay the price in our health, and in our future medical bills.
The statute (Public Law 101-445, 7 U.S.C. 5341 et seq.) that required the guidelines specifically says that the Dietary Guidelines be based on the preponderance of current scientific and medical knowledge. As that wouldn’t be the case, unless the restrictions are removed, I expect that from 2020 to 2025 I’ll be advising my patients to follow the 2015 guidelines.
