Soy is a great source of protein for vegans because it is considered a complete source of protein, which means it provides all the essential amino acids needed to optimise human health. As a matter of fact, soy protein is correlated with healthy cholesterol levels and a reduced risk of heart disease. Soy protein is particularly popular among women, and for good reason! Research shows that regular consumption of soy protein can increase bone mineral density and improve peri- and post-menopausal bone turnover rates. Soy protein is also an excellent source of calcium, iron, potassium, omega-3 fatty acids and fibre. Our soya proteins are (like all those we use) GMO-free.
Nutritional and health benefits of soya protein isolate
Soy protein isolate is a complete vegetable protein. It contains all the essential amino acids for growth and is equal in quality to meat, milk and egg protein. In addition, it has a low fat content. Soy protein isolate may reduce the risk of coronary heart disease. There are also indications that soy protein may help in the prevention of osteoporosis, certain forms of cancer and menopausal symptoms. The isoflavones contained in soy have many health benefits such as improving arterial vasodilation, atherosclerosis and lowering cholesterol.
Soya protein and cancer risk
Epidemiological studies suggest that soy protein may reduce the risk of some cancers, including breast and prostate cancer. Japanese people, who eat a lot of soy protein (especially soy and miso tofu), have a much lower risk of breast or prostate cancer than Western people. The anti-cancer effect of soy protein could be explained by phytochemicals, which are associated with soy protein. These phytochemicals are isoflavones (genistein, daidzein and glycitein), phytic acid and saponins. Isoflavones and phytic acid have strong antioxidant properties and can prevent oxidative free radical damage to our DNA and cells. Shu X.O. et all suggests that high soy intake during adolescence may reduce the risk of breast cancer later in life (Soyfood Intake during Adolescence and Subsequent Risk of Breast Cancer among Chinese Women. Cancer Epid Biomarkers Prev. 10: 483-488 ). The inverse association between soy protein intake and breast cancer risk reduction was observed for each soy food examined.
