Consuming more protein might not exactly benefit older men much

According to some study conducted by Brigham and Women’s Hospital, older men that consumed more protein than the recommended dietary allowance didn’t see increases in muscle, muscle performance, physical function or some other well-being measures.?No matter if a adult is young or old, woman or man, their recommended dietary allowance (RDA) for protein, set by the Institute of drugs, is the similar: 0.8-g/kg/day.

Many experts and national organizations recommend dietary protein intakes greater than the recommended allowance to help maintain and promote muscle boost in older adults. However, few rigorous studies have evaluated whether higher protein intake among seniors provides meaningful benefit.

A randomised, clinical trial conducted by Brigham and Women’s Hospital investigator Shalender Bhasin and colleagues has found that higher protein intake couldn’t increase muscle, muscle performance, physical function as well as other well-being measures among older men.

“It’s amazing how little evidence there may be around simply how much protein we must have in our diet, especially the price of high-protein intake,” said corresponding author Bhasin. “Despite a lack of evidence, experts go on to recommend high-protein intake for older men. We planned to test this rigorously and discover whether protein intake higher than the recommended dietary allowance is beneficial in increasing muscle mass, strength and wellbeing.”

The clinical trial, referred to as the Optimizing Protein Intake in Older Men (OPTIMen) Trial, would have been a randomised, placebo-controlled, double-blind, parallel group trial during which men aged 65 or older were randomized to have eating better containing 0.8-g/kg/day protein and also a placebo injection; 1.3-g/kg/day protein in addition to a placebo injection; 0.8-g/kg/day protein including a weekly injection of testosterone; or 1.3-g/kg/day protein plus a weekly injection of testosterone.

All participants ingested prepackaged meals with individualized protein as well as energy contents and supplements. Seventy-eight participants completed the six-month trial.

The team discovered that protein intake in excess of the RDA didn’t have major effect on muscle tissue, fat mass, muscle performance, physical function, fatigue or any other well-being measures.

“Our data highlight the necessity for re-evaluation on the protein recommended daily allowance in older adults, specifically those with frailty and chronic disease,” the authors concluded.
