Rethinking the RDI of protein

Tuesday, 28 July, 2015

Recommendations for protein intake are based on outdated research techniques and may need to be updated, according to Canadian researchers.

In a paper published in Applied Physiology, Nutrition, and Metabolism, researchers put the focus on protein as an essential component of a healthy diet. Protein helps people stay full longer, preserves muscle mass and, when combined with adequate physical activity, has the potential to serve as a key nutrient for important health outcomes and benefits.

The findings indicate that current dietary protein recommendations may not be sufficient to promote optimal muscle health — especially in ageing populations, which are prone to muscle loss. The study suggests that including a moderate amount of high-quality protein in each meal may offer an effective strategy for optimising muscle protein synthesis and potentially protecting muscle mass.

The researchers suggest that healthy protein choices, combined with physical activity, is an essential approach for policy makers attempting to control the obesity epidemic.
