How obsessing over protein could be harmful to your health
If you’re like me, you often find yourself confused by how many health headlines contradict one another. Lately, I’ve found this to be true where protein is concerned, particularly the protein needs of adults aged 50 and over.
In one study, published Jan. 1, 2015, in the American Journal of Physiology’s Endocrinology and Metabolism, scientists split 20 adults aged 52 to 75 into one group that consumed the U.S. RDA recommended level of protein, and another group that consumed double that amount, measuring levels of whole body protein at the beginning and end of the trial. While both groups maintained a positive protein balance (their bodies synthesized more protein than they broke down), the higher protein group ended up with a higher overall protein balance than the lower protein group. The news media jumped all over this, proclaiming that older adults should double their protein intake if they want to live long, healthy lives.
