In a previous article, I gave 7 reasons why you should avoid soy as a food.
It caused quite a stir on our Facebook Group as many people seem to be still buying the idea that soy is a health food.
So, here are a few more reasons NOT to consume soy
1) Soy is one of the most sprayed crops in the World.
Soy is one of the crops that get sprayed the most with pesticides, rodenticides and fungicides. Some of these chemicals that we find in the soy foods accumulate in the fat tissues. Want a great recipe to stay fat? Consume toxic foods, as the body’s natural defense when it can’t get rid of all of it with the detox organs is to store it in the fat cells.
2) Soy’s purported health effects are unclear
Soy isoflavones have at best a mixed record in science when it comes to health effects, and there is some evidence (1,2) that daidzen and genistidin could do more harm than good, such as promoting estrogen-sensitive cancers.
You also have to consider that all the places where people supposedly consume soy as a health food, also have a iodine-rich, traditional diet, especially Japan. Okinawa, one of the Blue Zones on the planet where there is a high concentration of centenarians, is where the soy craze originates. Coincidentally, it is also an island known for its high seafood and green tea consumption.
3) Soy can delay child development
Soy can affect development of the foetus and later in life increase the likelihood of prostate cancer in males, as well as have reproductive consequences. It also leads to delayed puberty in boys and early puberty in girls (4, 5)
How about fermented soy products? They are allegedly better, since fermentation deactivates some of the most harmful compounds, but the phyto-estrogens and goitrogens (thyroid suppressing) remain. If you like miso, natto, tempeh or tamari, you can have some on occasion, but the reason should be because you like them, not because you want to take advantages of their health properties by having large servings of them on a regular basis, since you’re bound to suffer their double-edged effect as well.
