The Soy Controversy

Whether or not soy enhances female fertility seems to be an area of controversy.  Some sources say soy can actually be detrimental to fertility because the phytoestrogens could act as a contraceptive.  However, one study, although done on monkeys (who have menstrual cycles similar to humans), concluded that even though it may lengthen menstrual cycles (which, for me, was a good thing), it did not harm fertility.[1]

Critics of soy mention other reasons it may harm fertility and health including:

·         Soy is considered a “goitrogen” which may make it harder for the thyroid to make hormones.

However, when studied, this appeared to only be true in populations deficient in iodine.[2]

·         Soy is frequently genetically modified (see my “things to avoid” section).   When I came up with my fertility diet, less was known or publicized about genetically modified foods.  If you do decide to make soy a part of your diet, talk with your local health food store about non GMO soy products.

·         Most Americans are consuming unfermented soy which is supposedly worse than the fermented variety.  Unfermented soy has phytates which may interfere with nutrient absorption.  Some of the most popular unfermented soy products are soymilk, tofu, soy nuts and soy meat alternatives.  Fermented soy includes miso, soy sauce, tempeh, and natto.

So, who do you believe?   The Agency for Healthcare Research and Quality was unable to substantiate claims that soy products (both fermented and unfermented) were harmful or helpful to endocrine function although soy did seem to reduce the incidence of hot flashes.[3]

I'm a firm believer that all foods should be consumed in moderation and you should vary your diet.  I did eat soy when I was trying to conceive, but I ate plenty of other foods as well.
