New Dietary Guidelines Urge Focus on Whole Foods for Better Health

American Medical Association (AMA) President Bobby Mukkamala, MD, highlighted the importance of diet and access to healthy foods for patient health. In an AMA webinar, Dr. Mukkamala, along with experts Christopher Gardner, PhD, and Dariush Mozaffarian, MD, discussed key aspects of the updated guidelines and strategies for effectively counseling patients about their diet.

Dr. Mozaffarian pointed out that poor nutrition has significantly contributed to the surge in chronic diseases over the past 30 years, noting that half of U.S. adults either have diabetes or prediabetes. He stated that three in four Americans are overweight or obese, and 93% exhibit suboptimal cardiometabolic health. Diet-related issues result in 10,000 deaths, 16,000 new diabetes cases, and 1,500 new cancer cases each week, costing the healthcare system an estimated $1.1 trillion annually. He asserted that prioritizing food within healthcare is essential.

The webinar titled “Dietary Guidelines: What Physicians Need to Know” is available on the AMA Ed Hub™, where attendees can also earn credit towards continued medical education. This session was the first in a series that includes upcoming topics such as understanding processed foods, navigating protein intake, and reducing chronic disease risks through diet.

Dr. Mozaffarian outlined pivotal changes in the guidelines, particularly the focus on “real” foods and the need to limit processed foods high in sugar, sodium, and artificial ingredients. The new guidelines reject the previous approach that obscured the dangers of such foods behind nutrient targets, shifting instead to directive language that includes strong recommendations to avoid harmful foods.

Key recommendations from the guidelines include an increased emphasis on fiber-rich whole grains, healthy fats from whole foods, and a modest increase in protein intake to 1.2–1.6 grams per kilogram of body weight per day. For the first time, whole-fat dairy with no added sugars is recommended. While guidance for fruits and vegetables remains consistent—with two to three servings of each recommended per day—the guidelines also stress limiting sodium and capping saturated fat intake at 10% of total daily calories.

In a notable structural change, the food pyramid has been revised to place fruits, vegetables, protein, dairy, and healthy fats at the base, moving grains to a less prominent position. This new structure highlights that approximately 60-70% of the pyramid should consist of plant-based foods, with 30% allocated to animal foods, underscoring the shift towards a diet focused on whole, minimally processed foods.

Despite the updated guidelines, there remains a significant gap between recommended diets and actual eating behaviors among Americans. Dr. Gardner noted that data indicates most individuals do not meet the recommendations for fruits, vegetables, and whole grains while consuming excess refined grains. He suggested that doctors engage patients by discussing typical meals to better understand their dietary habits and provide tailored nutritional advice.

Dr. Mozaffarian also stressed that while the guidelines are aimed at the healthy general public, there are limitations for populations with specific health conditions. He called for more research to better inform nutritional guidance for patients with diseases like cancer.

Panelists agreed that while doctors play a critical role in promoting better nutrition, systemic changes across medical education, clinical pathways, and reimbursement policies are necessary. Dr. Mozaffarian's organization employs a quick screening tool to assess barriers patients face in accessing nutritious food, such as cost, availability, and knowledge, emphasizing the importance of understanding patient circumstances to effectively address their dietary needs.
