| The humble soybean has become a source of controversy, with some accusing the legume of all sorts of adverse health effects.
The Harvard Women's Health Watch has published an article in its June 2011 issue, stating, "a large study suggests that breast cancer survivors can safely eat soy foods." These findings were presented in April at the annual meeting of the American Association for Cancer research. |

| The studies involved more than 18,000 breast cancer survivors in China and the US. After 9 years, there was little difference in risk of recurrence or death when the researchers compared women who ate the most soy with those who ate the least. In fact, soy was associated with a statistically insignificant improvement in longevity.
My thoughts on the above: There is nothing in this world without risk. Soy is a complete protein, and a renewable resource. Organic soy is a plus for the earth (provided that people aren't cutting down rainforest to grow soy) Other sources of complete protein are more problematic. Humans are degrading the climate and laying waste to the oceans to obtain beef and fish protein. Encouraging people to eat more tofu would be environmentally positive.
Two side issues:
It has been argued that Asians eat a great deal less soy than American vegetarians. If so, they would be risking pellagra. According to the study, Chinese women had an average daily intake of two or three "servings" of tofu. (whatever "servings" means)
The study measure the effect of soy FOOD. It is very possible that various extracts of soy that are sold in pill form may be bad for you. |
