What kinda food can we stock up to help increase breastmilk supply?

I think different people will have different food that will work for them. Some of my friends always resort to nuts, dried fruits and oats. It works like a charm for them. Some even experimented with lactation cookies to make it more fun. There are few recipes out there that you can give a try. Bake and stock them up! Have it as a snack or something :)
