Is an Excess of Soy Linked to Cancer?

This morning, I received an email warning me about the negative effects too much soy can have on one's body. The message mentioned that there is a large amount of literature on soy boasting its wonderful health benefits (i.e. protection against heart disease and breast cancer, cholesterol lowering properties, etc). "It is the magical isoflavones, the estrogen-like hormones that work to help you stay young and healthy". Anyone reading this that is health-conscious would definitely consider adding soy to their diet, but what isn't mentioned is that soy's estrogen-like qualities are exactly why too much MAY be bad.

One woman tells her story of how she wanted to be healthier so she began fortifying her body with the foods she had read would make her healthy and strong. Tofu was her main protein in every meal, she drank ample amounts of soy milk and snacked on soy muffins, miso soup with tofu, soybeans, soybean sprouts, etc.

Seven years after these "healthy" changes, this woman was told that she had two tennis ball sized cysts in her uterus. A couple of years later, they discovered a lump in her breast. Two years after that, her glands swelled and her gums became inflamed. She was eventually diagnosed with Papillary Thyroid Carcinoma. What was going on with this woman?? After extensive research, this is what she found: Breast cancer is linked to estrogen. What mimics estrogen in the female body? SOY!

Immediately after reading this email, I visited the snopes website and apparently there is some truth to this story. According to snopes, research is still in the beginning stages of fully understanding if soy is something that people, especially women, should be avoiding. Is an excess of soy linked to cancer? At this time, it is inconclusive. Some initial studies have shown that soy could stimulate estrogen-dependent tumors yet others have shown that soy may help PREVENT breast cancer.

So, what do we do with this information? Personally, I will not be cutting soy from my diet COMPLETELY, but will instead begin alternating my milk choices between soy, rice, almond and hemp. It seems to me that moderation is key no matter WHAT you are eating.

    I have cut dairy and then soy from my diet because my daughter has sensitivities to both, and I found that once the dairy was gone, cutting soy was not as tough as I thought it would be.
    Eliminating dairy gets rid of a lot of processed foods that would also have soy in them.
    But then, it may also cause you to begin using a lot of dairy alternatives that are soy-based. I think that mixing up the types of milk you consume is a good idea.

    As a vegetarian, my "meat alternative" of choice having neither dairy nor soy is Quorn's Naked Chik'n Cutlets. I find them at the Mississippi Market co-op. Some other Quorn items do have dairy, though.
