USDA releases new dietary guidelines with changes in protein recommendations

On January 7, 2026, the U.S. Department of Agriculture (USDA) and the U.S. Department of Health and Human Services (HHS) released an updated version of the Dietary Guidelines for Americans. This new edition introduces a revised food pyramid graphic and updates several nutritional recommendations.

The Dietary Guidelines for Americans are published every five years to provide advice on healthy eating and drinking habits that can help prevent diet-related diseases. These guidelines serve as a resource for policymakers, nutrition program operators, healthcare providers, and educators.

Vanessa da Silva, director of the Diabetes Prevention Program at University of Arizona Cooperative Extension, explained the main message: “They use the term ‘real food’ in opposition to processed or ultra-processed foods,” she said. “What they’re saying is that for the health of Americans, we should all be eating foods that are in their whole, intact state – or as close to that as possible.”

The updated guidelines recommend prioritizing protein at every meal, consuming fruits and vegetables throughout the day, incorporating healthy fats, focusing on whole grains, and minimizing highly processed foods along with refined carbohydrates and added sugars.

For adults following a 2,000 calorie per day diet, recommended daily servings include:
– Protein: 1.2 – 1.6 grams per kilogram of body weight
– Dairy: 3 servings
– Vegetables: 3 servings
– Fruits: 2 servings
– Whole grains: 2 – 4 servings

Ashley Carrillo, assistant professor of practice at the School of Nutritional Sciences and Wellness at University of Arizona CALS, noted that much remains consistent with previous editions but there is now more emphasis on sources of nutrients. “Previous iterations of the guidelines also prioritized protein and encouraged eating fruits and vegetables and choosing fiber-rich whole grains,” she said. “A lot of what’s changed is the emphasis on where those nutrients are coming from.”

One notable change involves increased protein recommendations—from 0.8 grams per kilogram to between 1.2–1.6 grams—and a greater focus on animal-derived proteins compared to earlier plant-forward guidance.

Other differences include support for full-fat dairy over low-fat options and a recommendation against any added sugars for children under age ten.

These shifts have raised concerns among some professionals about practicality and potential unintended consequences. Da Silva commented on saturated fat intake limits: “They’ve maintained the longstanding cap on recommended intake of saturated fat at no more than 10% of daily calories. If you’re consuming a lot of full-fat dairy – which has more saturated fat than the low-fat version – there’s a lot of potential to go over that 10% cap, especially if you’re also getting a lot of your protein from animal sources.”

Carrillo addressed worries about restricting added sugar for children: “Beyond the question of whether it’s realistic to restrict kids from all sources of added sugar, there’s reason to be concerned about what this might do to kids’ relationships with food in the long run,” she said. “We know that restriction can contribute to disordered eating behaviors like hiding food, binging behavior and just general anxiety around those restricted foods. It also seems to disregard that we don’t just eat for nourishment – that food can also be a source of joy and connection.”

The visual representation accompanying these guidelines has shifted back from MyPlate—used since 2011—to an inverted pyramid design released in January 2026. The new pyramid places protein and vegetables at its base while moving whole grains to its smallest point—a reversal from previous versions.

Carrillo pointed out possible confusion arising from this shift: “When you look at the new pyramid, whole grains appear in a very small section just at the bottom, which seems to suggest that they’re being de-emphasized,” she said. “There’s a potential disconnect between the image and the actual guidelines, which recommend 2-4 daily servings of grains.”

The impact extends beyond individual choices; these guidelines inform policies affecting school lunches, healthcare facilities funded by federal programs, prisons—and other institutions where meals make up most or all daily nutrition.

“The 400-page scientific report that accompanies these guidelines is going to inform policy decisions for the next five years,” Carrillo stated.

Da Silva highlighted implementation challenges within institutions: “If we have to prepare more foods from scratch…institutions will need more capacity…they’ll need trained staff…All of that would require funding…”

Despite regular updates since their first publication in 1980—and widespread dissemination—compliance remains low among Americans overall.

“Americans have not been meeting the dietary guidelines – ever,” da Silva observed.“So what do they really mean in practice? To really improve health at a population level…the guidelines need to be accompanied by policies that improve access…and meet people where they are…”
