Is Soy Healthy?

The answer may come as a surprise to you. Over the years many people have started to substitute foods with soy products for what may be a healthier choice. However, recent studies have shown that soy contains a natural chemical that mimics estrogen, a female hormone. Eating too much soy can potentially be harmful. Originally soy has been promoted to reduce heart, breast and prostate disease and lower cholesterol. According to the Environmental Health News, soy may “reduce fertility in women, trigger early puberty and disrupt development of fetuses and children and changes in the reproductive development” (Konkel; 2009). These tests have only been conducted on rodents thus far, however scientists do believe it just be as effective in humans. It may be beneficial to study the products you and your family eat, especially during pregnancy and child development.

But all may not be lost for soy products. Studies indicate that fermented soy such as miso and tempeh may be healthy to consume. The fermentation process effectively breaks down the very high levels of phytic acid and other anti-nutrients in the soy, thereby permitting ease of nutrient absorption during the digestive process (Wang; 1994). Fermentation may also add critical vitamins such as K2.
