Is Soy Safe?

Is Soy Safe

Unless you have an allergy to soy, you can stop stressing about soy.

Actually, soy consumption has been associated with decreasing risk of certain cancers and promote cardiovascular health, balance your hormones and easy on your kidneys.

Soy beans are high in nutrients the same as you tend to associate with other legumes, including fiber, iron, magnesium, potassium, and protein.

What are the best sources of soy?

“Soybeans naturally contain a class of phytoestrogens called isoflavones.

People hear the word “estrogen” in the word “phytoestrogens” and assume that means soy has estrogen-like effects.

Not necessarily.

Estrogen has positive effects in some tissues and potentially negative effects in others.

For example, high levels of estrogen can be good for the bones but can increase the likelihood of developing breast cancer.

Ideally, you’d like what’s called a selective estrogen receptor modulator in your body that would have proestrogenic effects in some tissues and antiestrogenic effects in others.

Well, that’s what soy phytoestrogens appear to be.

Soy seems to lower breast cancer risk, an antiestrogenic effect, but can also help reduce menopausal hot-flash symptoms, a proestrogenic effect.

So, you may be able to enjoy the best of both worlds.

What about women with breast cancer?

Overall, researchers have found that women diagnosed with breast cancer who ate the most soy lived significantly longer and had a significantly lower risk of breast cancer recurrence than those who ate less.

The quantity of phytoestrogens found in just a single cup of soymilk may reduce the risk of breast cancer returning by 25 percent.

The improvement in survival for those eating more soy foods was found both in women whose tumors were responsive to estrogen (estrogen-receptor positive breast cancer) and those whose tumors were not (estrogen-receptor negative breast cancer).

This also held true for both young women and older women.

In one study, for example, 90 percent of the breast cancer patients who ate the most soy phytoestrogens after diagnosis were still alive five years later, while half of those who ate little to no soy were dead.

Soy consumption has also been shown to benefit our kidneys, which appear to handle plant protein very differently from animal protein.

Within hours of eating meat, our kidneys rev up into hyperfiltration mode.

But, an equivalent amount of plant protein causes virtually no noticeable stress on the kidneys.

Eat some tuna, and within three hours, your kidney filtration rate can shoot up 36 percent.

But eating the same amount of protein in the form of tofu doesn’t appear to place any additional strain on the kidneys.” -Dr Gregor
