Robert F. Kennedy Jr. on Friday criticized the long-standing federal food pyramid during a House hearing, arguing that past dietary guidelines encouraged Americans to consume large amounts of ultra-processed foods and refined carbohydrates.

Testifying before lawmakers, Kennedy said the original model, developed decades ago, placed heavy emphasis on foods such as bread, cereal, and pasta while limiting recommended intake of proteins and fats. He argued the framework reflected industry influence rather than public health priorities and contributed to what he described as a broader metabolic health crisis.

The comments came in response to a question from Rep. Glenn Grothman regarding the impact of federal dietary guidance on children’s health.

Kennedy said a large share of modern American diets consists of ultra-processed foods, estimating that roughly 70 percent of calories consumed fall into that category. He linked those trends to rising rates of chronic conditions, including diabetes, particularly among younger populations.

He pointed to a significant increase in cases of Type 2 diabetes among teenagers, describing it as a marked change from previous decades when the condition was relatively rare in children. Kennedy also cited broader concerns about national health, including rates of chronic disease and physical fitness among youth.

The criticism aligns with a shift in federal dietary messaging under the Trump administration, which has promoted updated guidance emphasizing whole foods and reduced reliance on processed products. The revised approach encourages higher intake of protein, healthy fats, fruits, vegetables, and whole grains, while discouraging refined carbohydrates.

Kennedy said the new direction aims to reverse prior policies that he argued contributed to poor health outcomes, adding that future guidelines will focus on nutrient-dense foods and long-term disease prevention.

The remarks reflect an ongoing debate over the role of federal nutrition policy, industry influence, and dietary habits in shaping public health outcomes across the United States.
