Nutrition experts weigh in on US dietary guidelines

Americans should eat more beans, peas and lentils and cut back on red and processed meats and starchy vegetables, all while continuing to limit added sugars, sodium and saturated fat.

Thats the advice released last week by a panel of nutrition experts charged with counseling the U.S. government about the 2025 edition of the dietary guidelines that will form the cornerstone of federal food programs and policy.

But the 20-member panel didnt weigh in on the growing role of ultraprocessed foods that have been linked to health problems, saying theres not enough evidence to tell people to avoid them. And the group steered clear of updating controversial guidance on alcohol consumption, leaving that analysis to two outside reports expected to be released soon.

Overall, the recommendations for the 2025-2030 Dietary Guidelines for Americans sound familiar, said Marion Nestle, a food policy expert.

This looks like every other set of dietary guidelines since 1980: eat your veggies and reduce consumption of foods high in salt, sugar and saturated fat, Nestle said in an email. This particular statement says nothing about balancing calories, when overconsumption of calories, especially from ultra-processed foods, is the biggest challenge to the health of Americans.

The nutrition panel concluded that a healthy diet for people aged 2 years and older is higher in vegetables, fruits, legumes, nuts, whole grains, fish and and vegetable oils that are higher in unsaturated fat.

It is lower in red and processed meats, sugar-sweetened foods and beverages, refined grains and saturated fat. It may also include fat-free or low-fat dairy and foods lower in sodium and may include plant-based foods.

The panel, which met for nearly two years, was the first to focus on the dietary needs of Americans through what they called a health equity lens, said Dr. Fatima Cody Stanford, a Massachusetts General Hospital obesity expert who was part of the group. That meant considering factors such as household income, race, ethnicity and culture when recommending healthy diets. It will help ensure that the guidance reflects and includes various population groups, she said in an email.

Ultraprocessed foods include the snacks, sugary cereals and frozen meals that make up about 60% of the American diet.

The panel considered more than 40 studies, including several that showed links between ultraprocessed foods and becoming overweight or developing obesity. But the nutrition experts had concerns with the quality of the research, leaving them to conclude that the evidence was too limited to make recommendations.

That decision is likely to bump up against the views of Robert F. Kennedy, Jr., the nominee to lead the U.S. Health and Human Services Department, who has questioned potential conflicts of interest among members of the dietary guidelines panel and vowed to crack down on ultraprocessed foods that contribute to chronic disease.

The panel also didnt revise recommendations that suggest limiting alcohol intake to two drinks or less a day for men and one drink or less a day for women.

In 2020, the last time the guidance was updated, the government rejected the advice of scientific advisers to recommend less alcohol consumption.

Two groups the National Academies of Science, Engineering and Medicine and a committee of the government agency that oversees substance abuse are expected to release reports in the coming months on the effects of moderate alcohol use to inform the guidelines.

The advisory panel acknowledged that the diets of most Americans dont meet the current guidelines. More than half of all U.S. adults have one or more diet-related chronic health conditions and 18 million U.S. households have insecure sources of food, according to the report.

Nutrition-related chronic health conditions and their precursors continue to threaten health through the lifespan, the report concludes. Which does not bode well for the future of health in the United States.
