For nearly two decades, scientists have suspected that a link exists between soy and cancer prevention. Thousands of studies have been conducted to find out what effects, if any, the consumption of soy has on the incidence of cancer.
It’s the Isoflavones
So far, the results have been promising. It appears that isoflavones provide an anti-carcinogenic effect, and soy foods are the best source of isoflavones in the human diet.
Phytoestrogens and Cancer
Isoflavones are a type of phytoestrogens, compounds that are similar to estrogen. Phytoestrogens bind with the receptors that are normally used by estrogen, blocking some of the effects of estrogen. This action can reduce some of the ill effects of estrogen in both men and women.
Cancer-Blocking or Not, Soy is Great for Your Health
The result of this estrogen blocking may be the inhibition of certain cancers. Although the potential link between soy and cancer prevention is promising, it requires a lot of additional research. Regardless of whether soy proves to be cancer prohibitive in the end, it does carry other proven health benefits. So until science decides whether soy can prevent or inhibit cancer, we can continue to enjoy a multitude of delicious soy products and experience improved health.
