New Federal Dietary Guidelines Raise Questions from Health Community

-Editorial 

The U.S. Department of Health and Human Services, together with the USDA, announced a new food pyramid on Jan. 7 as part of the 2025–2030 Dietary Guidelines for Americans.

The new food pyramid differs from previous federal nutrition guidance by inverting the traditional hierarchy of foods. Instead of emphasizing grains as the foundation, the new model prioritizes protein, full-fat dairy, healthy fats, fruits, and vegetables, while placing whole grains at the bottom. It discourages refined carbohydrates, added sugars, and highly processed foods. It also almost doubles the recommended protein intake. 

Christopher Gardner, a professor of medicine at the Stanford University School of Medicine, said the new dietary guidelines released after the Jan. 8 advisory process have sparked debate among health professionals.

Gardner, who served on the most recent federal Dietary Guidelines Advisory Committee, said the panel of about 20 scientists spent two years reviewing research before submitting its recommendations to the U.S. Secretaries of Health and Human Services and Agriculture.

“The group reviews all new evidence and recommends, in an advisory way, not a demanding way, how they might update the guidelines based on new evidence,” Gardner said.

He described the experience as rewarding but said the final guidelines released by the administration differed in tone from the advisory report.

Gardner also noted the return of the food pyramid concept, which had previously been replaced by the plate model introduced during the Obama administration.

Michelle Obama helped shift federal nutrition messaging in 2011 to the MyPlate graphic, which encourages Americans to fill half their plates with fruits and vegetables, along with whole grains and protein sources.

“In the new version, we saw an upside-down pyramid,” Gardner said. “I think the flipping of the pyramid is a sensationalist approach to say this is so radical that we have flipped the whole pyramid upside down.”

Despite the change in presentation, Gardner said many of the recommendations remain similar to previous guidance.

“If you actually look at all the different domains of recommendations, most of them are consistent with old recommendations,” he said. “There’s really a lot of sound advice in the new dietary guidelines.”

However, Gardner said some elements conflict with the advisory committee’s conclusions. One major recommendation from the committee emphasized increasing consumption of legumes, beans, peas, and lentils, while reducing red and processed meat.

“We suggested across multiple domains that a consistent message we’re seeing is more legumes, beans, peas, and lentils, and less red and processed meat,” he said.

Gardner said he was surprised by the messaging surrounding the new guidelines that appeared to emphasize red meat and animal fats.

“It was a bit of a slap in the face to see that the pyramid had a big steak in the corner,” he said, adding that public messaging declaring “beef is back, butter is back” could overshadow other recommendations.

He also expressed concern about the emphasis on higher protein consumption.

“Protein has never been a nutrient of concern in these dietary guidelines,” Gardner said. “Given how much protein is being promoted in grocery stores these days, protein Pop-Tarts, protein water, protein everything, Americans may think all of that is justified.”

Gardner said he worries that consumers may interpret the new messaging as encouragement to increase protein intake beyond recommended levels.

The professor also highlighted the potential impact of the guidelines on federal programs such as school meals, which are required to follow federal nutrition standards.

“School lunch is an important issue because one of the places where the dietary guidelines has the biggest impact is in federal safety net programs,” Gardner said.

While he praised efforts to reduce ultra-processed foods and added sugars in school meals, Gardner said schools often lack the funding needed to provide healthier options.

“They’ve always been handcuffed by not having enough funding to provide healthy foods for schools,” he said.

Gardner said the full text of the guidelines offers more nuance than the visual pyramid itself, but he cautioned that simplified graphics and messaging can shape how the public understands nutrition policy.
