 In China, the soya bean has been cultivated and used in different ways for thousands of years. The increasing popularity of soya foods is mainly attributed to the large amount of health benefits which are associated with the use of soya beans. The role of soya in the prevention of chronic diseases continues to be a top priority for scientist around the world.
Soyfoods containing soy protein can be allies in the ongoing battle against heart disease, the number one killer of adult men and women. Over 40 scientific studies have proven the positive effect of soy protein on lowering cholesterol levels, including the harmful LDL cholesterol, which leads to the decreased risk of heart disease. In fact, the Food & Drug Administration recommends eating 25 grams of soy protein every day as part of a diet low in saturated fat and cholesterol. A serving of soy latte provides seven grams of soy protein, roasted salted soy nuts contain 12 grams and a soy cheeseburger has nine grams of heart-healthy soy protein.
Soy protein may provide positive results for people with high blood pressure. According to a recently published scientific study, researchers found that both the systolic and diastolic blood pressure were reduced in middle-aged and elderly women who ate at least 25 grams of soy protein daily. Since supermarkets today are filled with numerous soyfoods, eating 25 grams of soy protein is easy. Start the day with soy cereal for breakfast (eight grams soy protein). Add BBQ soy chips for lunch (seven grams soy protein). Grab a soy-protein-energy-bar for an afternoon snack (10 grams soy protein). Total soy protein equals 25 grams.
Certain fatty fish, like salmon and tuna, contain the best source of heart-healthy Omega-3 fatty acids. But certain plant foods, like flaxseed and soybeans, also contain these fatty acids. Soybeans are one of the best non-fish sources of essential omega-3 fatty acids, which may help reduce the risk of coronary heart disease. Compared to other beans like pinto beans and navy beans, soybeans have a higher fat content, but this fat contains these heart-healthy Omega-3.
While soy protein may or may not help reduce hot flashes for women going through menopause, soy protein has other proven benefits extending well into post-menopausal years. Research has found that consuming soy protein before, as well as after, menopause may help protect bones from becoming weak and brittle. And since post-menopausal women face an increased risk for osteoporosis, keeping bones healthy with soy protein-rich foods is critical.
