Soy beverages offer great taste, convenience, and high nutrition. Since soy is rich in Omega-3 fatty acids, the same beneficial substance found in fish, it helps to maintain a good level of HDL cholesterol. This is why the FDA claims that 25 grams of soy protein a day can reduce the risk of coronary heart disease. While the exact medical benefits of soy are constantly being evaluated, studies have shown that Asian countries where soy is a staple have lower rates of certain diseases, such as breast cancer.
