After drinking Shaklee’s soy shakes each day for over 20 years, I trust the safety and feel the energizing power. If you have any questions, Shaklee shares some research in the following article and if you would like to talk more about the benefits of soy, please let me know.
What Is Soy?
Soy is the perfect plant-based protein—it contains all 9 essential amino acids. The soybean is native to East Asia and is known mostly as an alternative to meat and dairy proteins. Soy has been a part of Asian diets for thousands of years—and for good reason. Today it is used worldwide because of its health benefits and many uses.
Did You Know?
Soy has isoflavones
Soy is the richest source of isoflavones that may help protect against several chronic diseases, including osteoporosis, coronary heart disease, and certain forms of cancer.
Soy is not feminizing
There are rumors that soy makes men more “feminine,” but studies show that it has no effect on estrogen levels in males, and it certainly does not “feminize” them.(8)
Soy doesn’t cause breast cancer
In fact, several recent studies show that soy consumption may be associated with a reduced risk of breast cancer recurrence and improved survival.(9)
