Scientists challenge the push to eat more protein

The push to eat more protein may not be as healthy as it sounds, according to a new scientific review.

Researchers examined more than 350 studies and found evidence that consuming less protein could trigger changes in the body linked to healthier aging and improved metabolism.

That does not mean people should stop eating the nutrient. It remains important for maintaining muscle, repairing tissue, and supporting recovery. But many adults already consume well above the basic recommended amount of 0.8 grams per kilogram of body weight each day.

Experts say people who already meet their protein needs may gain little by adding more through shakes, snacks, and fortified foods.

Some groups, including older adults, athletes, pregnant people and those recovering from illness, may need additional protein.

The findings don't mean you should drastically cut protein. Instead, they suggest that getting the right amount may matter more than simply getting more.
