Addressing the advantages and disadvantages of soy is somewhat complicated because the grain itself is very nutritious, and all its unprocessed derivatives are also; However, its bad reputation comes from its highly processed GMO version, which is unfortunately found in a huge number of products.
Below we present a list of 7 facts you should know about soy. These will help you understand why some doctors consider it a taboo cereal, while others praise its multiple properties:
Soy is the main ingredient in livestock feed: along with corn, processed (fat-free) soy feed is the main source of protein in farm animal feed. Its low cost allows the production of animals for human consumption to be carried out on an industrial scale.
The USA is the main producer of soybeans in the world: in 2011, 90 million tons were produced in this country. 93% of the soybeans coming from the United States have been genetically modified and there are currently no laws prohibiting GMO beans from being produced next to organic soybean fields.
Looks like estrogen: Soy contains isoflavonoids, which behave like estrogen. For this reason, soy is recommended for women going through menopause as it can control some of the symptoms. On the other hand, for this same reason, it is recommended that young boys (and girls) consume it moderately.
It can affect your thyroid (especially if you suffer from hypothyroidism): since soy is a goitrogen it sometimes causes thyroid disorders.
Most products use highly processed soy: Like wheat, one of the main problems with soy is that it is used in many processed products. The soy contained in some commercial cereals, snacks and breads has undergone a chemical treatment that removes all its original properties.
Soy is a complete protein: 100 grams of soy contain 173 calories with 9 grams of fat, 10 grams of carbohydrates, 6 grams of fiber and 17 grams of protein.
It has been consumed in Asian countries for thousands of years: soy production in East Asia began in 1100 BC. Currently, on average Japanese and Chinese consume 10 grams of soy protein every day. Most of the soy they consume is fermented (tofu).
In conclusion, soybeans are very healthy and can be an excellent alternative for those who do not consume animal proteins, or those who want to consume a little less. The important thing is to consume it in a natural presentation, in tofu, edamame or organic soy milk, and you should avoid processed soy at all costs.
