Soy is an excellent source of protein for vegans because it is considered a complete source of proteins, which means it provides all the essential amino acids needed to optimize human health. Soy protein is correlated with a healthy cholesterol level and a reduced risk of heart disease. Soy proteins are especially popular among women, and for a good reason! Research shows that regular consumption of soy proteins can increase bone mineral density and improve the rate of bone turnover in peri-and post-menopause. Soy proteins are also an excellent source of calcium, iron, potassium, omega-3 fatty acids and fiber. Our soy proteins are (like all those we use) GMO-free.
Nutritional and health benefits of soy protein isolate
Soy protein isolate is a complete plant protein. It contains all the amino acids essential for growth and is equal in quality to protein in meat, milk, and eggs. Moreover, it has a low-fat content. Soy protein isolate can reduce the risk of coronary heart disease. There are also indications that soy proteins can help in the prevention of osteoporosis, some forms of cancer and menopause symptoms. Isoflavones contained in soy have many health benefits such as improved arterial vasodilation, atherosclerosis, and decreased cholesterol.
Soy protein and cancer risk
Epidemiological studies suggest that soy proteins can reduce the risk of certain cancers, including breast and prostate cancer. Japanese, who eat a lot of soy protein (mainly soy and tofu miso), have a much lower risk of breast or prostate cancer than Westerners. The anti-cancer effect of soy proteins could be explained by phytochemicals, which are associated with soy protein. These phytochemicals are isoflavones (genistein, daidzein, and glycitin), phytic acid and saponins. Isoflavones and phytic acid have strong antioxidant properties that can prevent the oxidative damage of free radicals to our DNA and cells. Shu X.O. suggests that high soy intake during adolescence may reduce the risk of breast cancer in old age (Soy food intake during Adolescence and Subsequent Risk of Breast Cancer among Chinese Women Cancer Epid Biomarkers Prev. 10: 483-488 ). The connection between soy protein intake and breast cancer risk reduction was observed for each soy-based food tested.
