Soy – Yes or No?

Is Soy Good or Bad?

A study released in the Journal of Clinical Endocrinology and Metabolism this week showed consuming 50 mg a day of soy isoflavone improved the metabolic status of woman with PCOS including reducing triglycerides and improving insulin resistance as well as reducing alopacia or hair loss. In fact many studies have touted the benefits of soy for metabolic and cardiovascular health including improving cholesterol and in particular reducing the harmful LDL cholesterol.

But after enjoying years of fame, soy got a bad rap. Why?

Soy contains isoflavones that look chemically similar to estrogen and may theoretically mimic the effects estrogen in the body. This may be of concern in woman who have a known history of hormone-responsive cancers such as certain types of breast cancer.

However, for the majority, soy protein need not be avoided. Soy is a healthy vegetarian source of protein and an optimal replacement for animal proteins- in particular red and processed meats which are known to have negative health effects.

As always moderation is key. Somewhere between complete avoidance and 3 soy lattes a day is probably a good place to start!
