Soy has been promoted for years as a great health food. It is viewed as a healthier alternative to dairy and meat, and a good source of protein. But, what is the truth about soy? Well, it can be classified into two groups: fermented and unfermented. Unfermented includes tofu, soy milk, bean curd, soy infant formula, soy protein powders, soy meat alternatives such as those made from hydrolysed soy powder. Fermented includes organic miso, tempeh or tamari, etc.. In order to be able to benefit from the soy, it needs to be fermented. Why?
Because soy contains phytic acid, and it is only neutralized through the process of fermentation. So what are the dangers of eating unfermented soy with phytic acid?
1- The B12 analogs in soy are not absorbed and actually increase the body’s need for B12.
2- The phytic acid in soy beans reduce or even block assimilation of essential minerals such as calcium, iron, magnesium and iodine, which is used by the thyroid gland to produce thyroid hormones.
3- The plant estrogens found in soy, called phytoestrogens, disrupt endocrine function and have the potential to cause infertility and promote breast cancer in women.
4- It contributes to thyroid disorder.
5- Soy contains high levels of toxic aluminum, which causes adverse effects in the nervous system, kidneys and brain.
6- MSG, or free glutamic acid, is formed during the processing of soy, and is also added to many soy products.
7- The vast majority of soy in the U.S. has been genetically modified.
8- Babies fed exclusively on infant soy formula are receiving the estrogen equivalent to that of at least four birth control pills each day! In fact, many girls are showing signs of puberty at a much earlier age, such as breast development.
9- Babies fed infant soy formula have 13,000-22,000 times more estrogen than babies fed milk based formulas!
So you can see how deceptive the marketing can be. For example, the “health benefits” of it are often correlated to the fact that the Asian cultures eat large amounts of soy and thus do not suffer from many of the diseases of the Standard American Diet (SAD). However, the reality is that they eat very little amounts, in fact only about two teaspoons a day, and they eat it fermented and as a condiment, not as a meal.
