Soy Protein Promotes Men’s Health, Muscle Mass, and Strength

A recent surge in evidence from an array of sources highlights the nutritional and health attributes of soy protein for men. These sources include newly published research, the recently released 2020-2025 Dietary Guidelines for Americans and an authorized FDA health claim.

Nutrition scientists increasingly recognize the importance of maintaining muscle mass and strength throughout life. Consuming sufficient dietary protein helps to achieve this goal, but some have questioned whether or not the type of protein matters. In response, researchers statistically analyzed the results of 9 clinical studies involving men engaged in resistance exercise training.1 According to the findings, supplementation with soy protein led to gains in muscle mass and strength to the same degree as supplementation with animal protein (including whey protein which is often considered to be the gold standard protein for building muscle).
