In brazil we eat everyhing w corn and it helps so much! Cornbread... Cornmeal soup which it sounds weird but it taste delicious!!! Corn chips and even roasted corn!!!

Brewers yeast (use it in recipes to make cookies or in other recipes) that's what's in beer that makes it help your supply. But if you go the beer route it has to be dark beer (think Guinness)

my gyno told me beer (its gotta be obe made a certain way so google it) and oatmeal. some teas too but I don't remember the name.
