The new federal dietary guidelines released in January 2026 make one thing very clear. Officials want Americans to eat a lot more protein. The recommended intake now jumps well past what people have heard for decades, and the message is loud, simple, and hard to miss.
Many nutrition experts are not buying it. They say science does not support such a big shift for most people, and some worry the advice could backfire. Instead of improving health, critics argue it could increase chronic disease risk and fuel even more processed food consumption.
What Actually Changed in the Guidelines

The new 2025 to 2030 guidelines raise that range to 1.2 to 1.6 grams per kilogram, which can nearly double intake for some people.
The document also pushes a hard number, at least 100 grams of protein per day for adults. It suggests that half or more should come from animal sources like red meat, cheese, and whole milk. A new inverted food pyramid even places these foods front and center, sending a clear visual message about what matters most.
Why Officials Say More Protein Is Better
Leaders at the U.S. Department of Health and Human Services and the U.S. Department of Agriculture say the old protein target only prevented deficiency. They argue it did not support strong muscles, stable metabolism, or healthy aging. Their position is that more protein equals better function.
The guidelines cite a review of 30 studies that claim higher protein intake is safe for adults. Health Secretary Robert F. Kennedy Jr. framed the change as correcting years of bad advice, calling it an end to what he described as a 'war on protein.'
Nutrition Scientists Are Pushing Back
Many researchers say the average American already eats plenty of protein. Adult men in the United States consume close to 100 grams per day without trying. That means most people already meet or exceed the new target before making any changes.
Dr. Dariush Mozaffarian from Tufts University says the benefit is limited to specific cases. Extra protein can help people actively build muscle through strength training. For everyone else, he says the body does not need it and may turn excess protein into fat, especially visceral fat linked to diabetes risk.
Questions About the Science and the Process

Critics are also questioning how these guidelines were written. A 20-member scientific advisory panel from the previous administration gave different recommendations. Much of that work did not make it into the final document.
Instead, officials relied on a separate review group. About half of those experts disclosed financial ties to beef, pork, dairy, or related industries. Several scientists involved in earlier drafts say that their findings were ignored and that the final guidance contains serious errors.
Nutrition researchers worry the message will be picked up and twisted by food companies. Protein already sells, and this guidance gives brands official backing to add it to everything. Bars, cereals, snacks, and even bottled water already carry protein claims.
Christopher Gardner from Stanford University says this trend clashes with another goal of the same guidelines. Officials say people should avoid highly processed foods, yet protein is often delivered through ultra-processed products. Gardner predicts shoppers will simply buy more junk food with protein slapped on the label.
Organizations like the American Heart Association consistently recommend beans, nuts, seeds, and seafood over red meat and full-fat dairy. Critics say the guidelines send a mixed message by promoting foods that can raise saturated fat intake while warning people to protect their hearts.
