The Controversy About Protein Intake

"I started to recognize that even though it's so commonly said in the plant-based world that nobody ever gets, protein deficiency," says Michael Phelps. "That we may be needing to be a little more conscientious, especially during our senior years when we don't absorb amino acids as well" The RDA is set at 0.8 grams per kilogram body weight; average biological requirements are probably around 0.66. But some research shows athletes need to be consuming 1.2 to 2 grams of protein per kilogrambody weight.
