Although, soy and soy protein are often promoted as a healthy choice, there are several reasons why we recommend shying away from soy. Here are our top 5 reasons:
1. Soy is an Allergen. According to Health Canada the Canadian Food Inspection Agency (CFIA), allergy associations and the medical community, soy has been identified as one of the ten priority food allergens. A priority food allergen is a substance identified by the organizations and associations listed above as most frequently associated with food allergies and allergic-type reactions. (1)
2. 94% of Soy is Genetically Modified. (2) According to the USDA, the percentage of genetically engineered (GE) soybean in US reached 94% level in 2016. Although, not as high as the US, according to Statistics Canada, 58% of soybeans in Quebec and 61% of soybeans in Ontario were GM in 2014.(3) In Canada, GM foods do not have to be labeled. However, some food companies have chosen to label their products as “non-GMO”.
3. Taste is Unappealing. Taking just a sip or two after mixing a scoop of soy protein powder in a cup of water is all it takes for many people to decide that “it tastes so bad that they can’t get it down.” “The search for a better-tasting soy protein “may be fruitless because the best soy protein powders are designed to deliver the maximum amount of protein and are mass produced to accommodate many palates.”(4)
4. Soy is a trypsin inhibitor (5). Trypsin is a protein-digesting enzyme that is produced in the pancreas. Inhibiting protein digestion could lead to digestive distress including feeling gassy, bloated, pain and diarrhea.
However, if soy is fermented (ie. natto, tempeh, tamari and miso), it is expected most of the trypsin inhibitors are removed. So, it is better to consume fermented than non-fermented soy for health reasons.
5. Soy contains phytates. Phytates are the substance that blocks the absorption of essential minerals such as calcium, magnesium, copper, iron and zinc in the intestinal tract. Even if the soy is fermented, it is still unable to break down the phytates. (6)
