Soy has become a major source of toxicity for human beings, especially in the last three decades. Not only is more than 99% of soy genetically modified, but sources labeled organic or non-GMO are often exposed to the same problems as conventional soy. If you consume processed foods, soy is almost impossible to avoid. With the exception of wheat, there are few foods that are causing as many health problems as soy in the food supply.
Here are the reasons to avoid any kind of soy...
1. Soy Reduces Assimilation of Minerals
Phytic acid is present in the bran or hulls of all seeds and when we compare the phytate of soy to many other types of beans and nuts, the percent mass is not that far off, but that's not the problem. The problem is how much we are consuming. Most people stuck on the soy bandwagon are consuming far more phytate by the sheer volume through mass consumption of things like soy milk, tofu, cereals, and processed foods. It doesn't even compare to the amount they would consume through seeds and nuts. The effect of phytic acid on iron absorption has been thoroughly studied. As evident in a study in the American Journal of Clinical Nutrition, as phytic acid increases, it has a diminishing impact on iron while inhibiting its absorption. This applies to almost every major mineral including zinc--one of the most important minerals for the human body. Two billion people may now have zinc deficiency. Phytates bind to zinc and thereby decrease its bioavailability. Phytic acid levels in soy reduce assimilation of calcium, magnesium, copper, iron and zinc.
