Soy is a healthy whole legume that contains a wide range of healthy substances. It is rich in B vitamins, potassium, magnesium and quality protein. In 2019 the effect of soy consumption on health was evaluated on the basis of a meta-analysis. According to these data, people with the highest consumption of phytoestrogens (one of the biggest bogey in soy) also had the lowest risk of death of all the observed causes. Phytoestrogens are substances that are similar to the human hormone estrogen, but these behave differently in our body. According to studies, phytoestrogens bind to receptors that potentially suppress the growth of tumor cells. It is based on this fact that it can be said that soy is not the cause of cancer. Results from studies performed on a larger number of people indicate that consumption of soy does not affect testosterone levels or does not cause feminizing symptoms.
People suffering from thyroid disorders should be careful about soy intake. However, this legume is not the cause of decreased thyroid function, it only accelerates the manifestation of this disease. According to the British Dietetic Association, soy consumption has no detrimental effect on thyroid function in healthy individuals. It does not impair its function, but it can interfere with the absorption of thyroid drugs.
It is true that soy is one of the causes of rainforest felling, it is even in the second place. However, it is not about soy that is grown for the production of tempeh, tofu or miso. Most soybeans are used as a feed source for farm animals. Only about 6% of the world’s production of this crop is used for human consumption. In addition, this soy is not genetically modified, unlike the fodder one.
So, soy is a healthy crop that brings many benefits to the human body. The products available on our market are mostly made of soybeans grown in Slovakia or Austria. Due to its production, rainforests are not cut down and the soy is not GMO.
