Benefits Of Soy
- Soy contains weak, naturally-occurring phytoestrogens.
- Many studies have shown that regular consumption of phytoestrogen containing food reduces cancer by reducing the effect of estrogen on the body.
- Phytoestrogens are found in soy milk, tofu, quorn, tempeh and miso, plus pulses, linseeds and a variety of vegetables.
Soy And Estrogen
- Phytoestrogens in soy have a very weak effect compared to normal human estrogen or estrogen from animal sources.
- These phytoestrogens compete for the same hormone receptors and so reduce the effect of normal estrogen which has a much more potent effect on the body.
- They act as what’s known as ‘competitive inhibitors’ of estrogen
Does Soy Cause Cancer?
- Some research has shown that isolated isoﬂavones (phytoestrogens in soy), contribute to the growth of tumors in the breast, endometrium and uterus.
- This research has focused particularly on genistein, the most active soy isoﬂavone that activates estrogen receptors in breast tumors
No It Doesn’t!
- Soy, like all other whole-foods, does not equal the sum of its parts. Experts in the ﬁeld agree that research with isolated soy isoﬂavones, does not carry over very well to the effects of the whole food
- Studies do indeed show that when the various different isoﬂavones in soy are taken together, they have a powerful anti-estrogenic effect.
- They can protect you from your own elevated levels of estrogen, from estrogens in animal foods and dairy, and possibly even from xenoestrogens in environmental chemicals
Soy And Manboobs
- Multiple studies have found neither soy nor isolated isoﬂavones cause an increase in breast density, which is really what we man boob sufferers are worried about.
- Other studies have chimed in to show that increased soy consumption reduces other estrogen-sensitive cancers as well, such as lung and prostate cancer
Avoid Nonorganic Soy
- Soy milk, Soy yogurt, soy ice cream, soy cheese, Soybean oil, Soy protein, Meat alternative soy products, Soy infant formula, Edamame, Tofu
- Also, the processing of soy involves acid washing, neutralization solutions, and high temperature heating.
- Many of the original beneﬁts of soy are destroyed when they are processed. MSG is also often added to processed soy to improve its ﬂavor
Which Soy Should I eat?
- It’s important to get fermented soy because the process of fermentation reduces phytate levels in soy. Phytates are known to block the body’s absorption of key minerals like zinc, magnesium, calcium and iron.
- As mentioned earlier, good sources of soy include fermented tempeh, miso, natto and traditionally prepared soy sauce.
- Be careful with soy sauce though, because many varieties available in the west are made using an artiﬁcial, chemical processes
