Why Soy Products Are Bad For You

Jul 2, 2014 | Eating Right

Soy milk, soy sauce, soy protein, soy cheese, soy yoghurt, tofu… soy has become one of the most diversified and debated “foods” there is. So, let me clarify things.

Unfortunately, most of the soy we consume in developed countries is highly processed, and an extremely unhealthy and unnecessary inclusion. Here’s just a few reasons why you should say no to processed soy:

  1. High levels of phytoestrogen. In short, this creates an estrogenic (high estrogen) environment and as a result, lowers natural testosterone levels. Common symptoms include body fat accumulation, lowered libido and increased risks of infertility and cancer.
  2. High levels of goitrogens. These are compounds that inhibit the thyroid’s ability to utilise iodine efficiently and may lead to hypothyroid issues.
  3. Sugar. Soy dairy alternatives in particular, can often be packed full of sugar. Sugar is highly inflammatory, the number one cause of chronic disease. Short term, you’ll get an insulin spike, which creates the potential for incessant hunger, mood swings, poor food choices, and ultimately, fat gain.
  4. Artificial ingredients. Have you read the label of what you’re consuming? There is nothing natural about that “soy ice cream” or “non dairy frozen dessert” in your freezer. In addition, it should go without saying to avoid meal replacements and energy bars all together, but in particular, please steer clear of “soy protein isolate” and “texturised vegetable protein”. Your number goal should always be to just eat real food.
  5. Genetically modified (GM). In the US and Canada in particular, almost all soy that is not labelled organic has been genetically manipulated. We have different regulations in Australia, but that unfortunately doesn’t mean you’re not consuming GM foods without realising. This article gives a good summary of the status of GM foods in Australia. Please also consider the negative agricultural and environmental impact of such farming practices.

Soy Alternatives

Start with these four soy alternatives and you will not only be improving your health, but also conserving the environment.

  1. Nut milk: Delicious in coffee, tea, smoothies, porridge, and almost anywhere you’re currently consuming soy milk.
  2. Coconut aminos: a fantastic soy-free alternative to soy sauce and tamari, you can pick some up from your local health food store. I love to use mine in a stir fry or cauliflower fried rice.
  3. Chickpea tempeh: legumes aren’t what I consider a staple food (stay tuned for a blog post, coming soon), but in small doses they offer variety and additional protein, which is particularly important for those following a vegetarian or vegan lifestyle.

The exception to the rule: traditional or fermented soy foods such as tempeh or miso do often nutritional benefits but please choose organic and keep your intake to a minimum. When you find a research study that supports the health benefits of soy, please keep your perspective and first investigate who funded the study, and if in fact the results have been manipulated across to processed soy products.
