Q & A: Men, Soy Does Not Lower Testosterone

Soy gets a bad rap, people associate it with being a hippie and tree hugging, even though soy is a very healthy food, like edamame beans, but there is this silly notion that eating soy lowers testosterone and is bad for men. Not true. From his member center, Dr. Fuhrman talks about soy and manliness:

Question: My husband and I just started your plan, but recently my mother-in-law said that I was hurting my husband by making him eat more soy. She said that soy is not good for men because it contains phytoestrogens. Is what she is saying true? She cited an article in Men's Health that mentioned lower testosterone and sperm counts.

Dr. Fuhrman: Totally untrue, that is a biased, meat-promoting article written to bash soy. Men's magazines are not the place for reliable information about complicated health issues. If soy did lower testosterone it might be good because the high-meat American diet causes an excess of testosterone, leading to higher prostate cancer risk. Nevertheless this is not true anyway. See this study in the European Journal of Clinical Nutrition.

Plastic: More Study Needed on Phthalates

Experts want the Environmental Protection Agency to conduct a risk-assessment on the potential dangers of phthalates, chemicals used to make plastics soft and flexible, for things like toys, food packaging and medical devices. Currently, animal studies indicate phthalates may decrease testosterone levels in males and heighten risk of liver cancer. And many phthalates have already been banned in Europe for nearly a decade; via Reuters.

Bisphenol-A or BPA is another harmful chemical found in plastic drawing heavy scrutiny.
