Since the 90s, soy has risen to fame as a health food product and it has been advertised as an excellent protein source for vegans and vegetarians. Despite the praise that soy receives, there has also been a lot of controversy, especially relating to the link between soy and breast cancer. So what is true and what is false? We decided to take a deeper look at soy so that you can have all the facts.
Soy (or soybean) is a legume that is native to Asia. Soy is high in isoflavones, a plant estrogen. Isoflavones act like estrogen within the body but with a much weaker effect. There are a lot of factors to consider when evaluating whether these isoflavones are harmful, including ethnicity, hormone levels, and the type of soy that is used (unfermented soy vs. fermented soy), (1). Soy is a complete protein, meaning that it contains all the essential amino acids that the body cannot produce on its own. Because of this, soy has been used as a dairy alternative, meat alternative, and it is added into many products to boost protein content. (2)
Since soy has become popular, studies have been conducted to evaluate whether it is harmful or beneficial for humans to consume. Small studies have shown that soy can reduce menopausal symptoms, possibly reduce the chances of getting breast cancer and the recurrence of breast cancer, and can even protect against prostate cancer. Some studies have shown that soy isoflavones can also protect against cognitive damage. (3) It is important to note that many of these studies are small and have only been conducted on animals making it difficult to draw conclusions about the overall benefits of soy.One drawback with soy is that 90% of soybeans grown in the US are genetically modified and these crops are sprayed with chemical herbicides that can cause allergies, sterility, birth defects, and other issues. (4) In addition, many soy products are chemical extracts, not the whole legume, and these extracts are added to burgers and protein supplements. (5) Unfermented soy, even organic soy, contains antinutrients which can be harmful to the body and cause damage. While isoflavones can be beneficial, they have been shown to affect estrogen levels leading to certain types of cancer, hormonal imbalances, and infertility. (6)
Despite the controversy over unfermented soy, one thing remains true: fermented soy is a healthy food and is safe and beneficial to consume. Fermented soy has more protein than unfermented soy making it an even better protein substitute for vegans and vegetarians. (7) And those antinutrients in unfermented soy? Fermentation destroys all of them mitigating the negative effects that they might have. (8) Fermented soy is a good source of K2, a nutrient that prevents osteoporosis, cardiovascular disease, and dementia.
Fermented soy products nourish the gut, boost good gut bacteria, increase digestion, and aid in nutrient absorption. Our immune system starts in our gut, fermented soy has the positive side effect of improving immunity. It is also easier to digest. (9) Fermented soy, like miso, natto, and tempeh, is the best whole-food delivery of probiotics with complete amino acids, phytonutrients, and antioxidants. It is proven to be healing to the digestive tract and beneficial around the world for human health.
“Soy is only healthy if it is organic and properly fermented.”
Dr. Mercola (10)
In summary fermented soybean is different than conventional, over processed soy because it includes:
- Less immunoreactivity as identified in third party research.
- Contains all essential amino acids - the complete protein building blocks important for healing the intestinal lining
- Naturally occurring L-glutamine - an important amino acid to boost immune cell health in the gut.
- Bioavailable polyphenols - potent antioxidants only from plant sources that are fermented and easier to digest and absorb.
- Plus all the beneficial microorganisms, enzymes, nutrients and more.
