Wheat grass causing hormonal imbalances in women?

[Kathryn]

I posted this earlier in the Women's Health section, but no one responded, so I'm trying again here, to see in anyone else has heard of this (to confirm or refute):

 

I was in the health food store the other day, browsing through the book section, and in a book on detoxing, there was info on using wheat grass juice to detox, along with a statement that women shouldn't take the quantity suggested for detoxing because it can cause hormonal imbalances (no references or other info was given).

 

Anybody heard of this before? It's news to me.
