Diet While Breastfeeding

I received a question (via Amazon) regarding green powder, which I'd purchased through Amazon. The lady wanted to know if it was okay to drink green smoothies (made with green powder) while breastfeeding. Personally, I see nothing wrong with it. Green smoothies are healthy. Still, though, I suggested that she ask her pediatrician. Do you think it's safe?
