New research based on modern techniques suggests that recommendations for protein intake in healthy populations may be incorrect. In a paper just published in Applied Physiology, Nutrition, and Metabolism, an NRC Research Press journal (a division of Canadian Science Publishing), researchers put the focus on protein as an essential component of a healthy diet. Protein helps people stay full longer, preserve muscle mass, and when combined with adequate physical activity, has the potential to serve as a key nutrient for important health outcomes and benefits.
