Soy has been all the rage for quite a while now. Whether it’s vegetarians simply looking for a non-meat protein source or people just wanting something that is different, people are intrigued by soy.

I however am not impressed by soy. I’ll admit that even before entering the crunchy world, I was not a fan of soy. It’s just weird. However, after researching more about soy, I am definitely against it.
10 Reasons to Avoid Soy

10 Reasons to Avoid Soy

Soy is hard to digest – Soy contains enzyme inhibitors. It is these inhibitors that deter the body from breaking down the protein, which is in soybeans.


Soy is genetically modified –  90% of soy that is produced in the US has been genetically modified. Unless you buy organic soy, odds are good that the soy is a GMO.


Soy changes hormone levels – Soy contains phytoestrogens. When consumed these phytoestrogens mimic human estrogen. Now obviously we have estrogen in our bodies but adding more estrogen (especially “fake” estrogen) will only mess up your bodies system. Phytoestrogens have been linked to endocrine function and may cause infertility and may promote breast cancer. Soy is even more of a concern for the male population as it can cause baby boys to become “feminized” and when eaten during pregnancy can permanently lower a baby boy’s fertility. Many think that eating soy will help menopause symptoms but check out this post that explains why soy is actually a bad thing for menopause.


Soy is one of the highest pesticide crops – Food that has been essentially sprayed with bug poison is not on my list of things to eat.


Soy contains phytic acid – Soy has one of the highest levels of phytic acid. I’ve mentioned phytic acid before when I’ve talked about soaking grains. Phytic acid inhibits the body’s ability to absorb calcium, magnesium, iron, and zinc. Often times you can soak phytic acid containing foods so that some of the phytic acid is removed; however soy is resistant to such phytic acid reducing methods. Only long fermentation can help with phytic acid, which is why fermented soy is not all that bad.


Soy is one of the top 8 allergens – whether it’s because of soy being a highly processed food, a GMO, or something else entirely, more and more people are becoming allergic to soy.


Soy can mess up your thyroid – Soy is a goitrogen. Soy can interfere with thyroid function by hindering iodine metabolism.


Soy can cause Vitamin B12 issues – The b12 analogs that are in soy are not absorbed and in some cases can actually increase your body’s need for B12.


Soy can increase the body’s requirements for vitamin D– Most people are already deficient in vitamin D so eating soy can make that deficiency even worse.


Soy can contain high levels of aluminum  – High levels of aluminum usually result from the processing used for making soy products.


Not all soy is bad. If soy is organic and properly fermented then it’s fine and can even be a good thing.
