New U.S. dietary guidelines for Americans gave a big boost to protein. The latest edition advises eating “protein foods at every meal” and urges people to increase their daily intake of the vital nutrient — up to double the previous recommendation. The Trump administration's scientific review said the old limit was calculated only to prevent a nutrition deficiency and not to optimize health. Nutrition experts question the pro-protein push, saying most Americans already consume more protein than they need, and eating more could increase fat accumulation, leading to diabetes. They worry that companies will keep adding extra protein to processed food products.
