Soy and Men’s Health

Scientific research shows not only are soyfoods safe for men, but they can actually boost your health!

Soyfoods provide a great source of complete protein and nutrients with no cholesterol and very little saturated fat. Soy protein is a high-quality protein, which is key for performance in active and athletic men because it contains all of the necessary amino acids for muscle building and repair. Many studies have shown that soy protein, much like protein found in whey, can support increased muscle mass during resistance-type training. (1) Soy protein is the only complete plant protein that is equivalent to animal protein. (2)

The FDA recognizes that eating soy protein is good for your heart health. (3) When heart disease remains the leading cause of death in the U.S., men should eat soy protein, found to lower both the total amount of cholesterol and ?bad? LDL cholesterol.

Eating soyfoods may help protect against prostate cancer. Research suggests that regular consumption of soyfoods may reduce the risk of prostate cancer by as much as 30%. (4) No human research supports any negative effects of soy on male reproductive hormones.
