The Truth About Soy: Myths vs. Facts


Soy has gotten a bad reputation over the years. One person sees tofu, tempeh, or soy milk as nutritious staples, yet another hears “soy” and immediately thinks hormones, thyroid problems, or nutrient deficiencies. But how much of that concern is actually supported by human research?

Let’s take a closer look at some of the most persistent myths about soy.

Myth 1: Soy messes with your hormones

One of the biggest concerns about soy comes from its isoflavones, which are often called phytoestrogens. Because of this, some people worry that soy can increase oestrogen or lower testosterone. However, research in humans has found no significant effects on testosterone in men or reproductive hormones in women from soy or isoflavone consumption.


Myth 2: Soy is bad for your thyroid

There are also concerns that soy may be harmful to the thyroid. However, these concerns are largely based on laboratory and animal studies. Clinical research found that soy foods and isoflavones do not adversely affect thyroid function in healthy humans.


Myth 3: Soy causes cancer

What about cancer? Despite concerns surrounding soy and breast cancer, research has been reassuring. The American Cancer Society and American Institute for Cancer Research concluded that women with breast cancer can safely consume soy foods. Some research has even found that higher soy intake after diagnosis may be associated with better survival.


Myth 4: Soy blocks your nutrients

Another common claim is that soy prevents your body from absorbing important nutrients. While soy contains phytate, which can affect mineral absorption, research has found that iron from soy can be highly bioavailable. Calcium absorption from foods such as calcium-set tofu and fortified soy milk can also be comparable to that from cow’s milk.

 

So, is soy bad for you? For most people, the evidence says no. Many of the concerns surrounding soy come from animal or laboratory studies, while research in humans paints a much more reassuring picture. In short, there’s no need to fear soy simply because you’ve heard the myths.
