Which food I should avoid during breastfeeding?

I guess avoid foods that are heavy to digest or can cause gas or are acidic in nature. It is because this food is going to make the milk which the baby is going to drink, and it may cause gastric or colic in baby. Or even if you want to have such food, have in moderation. http://www.webmd.com/parenting/baby/ss/slideshow-breastfeeding-foods
