Is Soy Good or Bad for Human Body?

Published Date : Feb 04, 2016

Soy milk has emerged as a healthy alternative. According to a new study published in the Journal of Clinical Endocrinology and Metabolism, soy fights some of the harmful effects of BPA exposure. BPA or Bisphenol A is an organic synthetic compound and is found in polycarbonate plastics and epoxy resins. BPA has been termed as carcinogen by many researchers and has been linked to infertility. It is found in many plastic products and household goods and according to the Centre for Disease Control and Prevention (CDC), BPA is present in more than 96% of Americans’ bodies. Higher BPA levels have been associated with decrease chances of embryo implantation and fewer live births.  

Study Examines Link between Soy & BPA in Humans

According to Jorge E. Chavarro, the lead author of this study, previous reports studying the effects of soy on human body have pointed that soy works by preventing BPA from adding methyl groups to human DNA. However, this study is the first to examine the link between soy and BPA in humans. Chavarro suggests that women might benefit by eating at least one extra serving of soy such as tempeh, tofu, and edamame. 

However, it is interesting to note that too much of soy can temporarily shut down a woman’s menstrual cycle. Hence, experts have pointed that the overall effects of eating large amounts of isolated soy products such as soy protein isolate powders and supplements are still unknown. To maximize the potential benefits of eating soy, consumers should eat natural, minimally processed sources. One to two servings of minimally processed or whole soy per day is generally considered as safe by nutritional experts. One serving of soy refers to about 1 cup of soy milk or edamame, or half cup of soy milk alternative, or soybeans, or tofu.
