FTM: Good diet for breast feeding??

Hello! Just curious what are you mamas diets for breast feeding? I've been reading that certain foods can make the baby gassy such as milk. I drink milk but I'm probably going to switch to something else. I also am considering juicing with veggies and fruit (of course not in place of a meal) but just to add more nutrients to my diet bc I know I don't eat the healthiest on a day to day basis. I currently am using the enfamil gentlease formula and it works well bc we don't have issues w baby being gassy and we put it in a Doctor Browns bottle but I'm afraid that once I switch to breast milk he'll be more fussy.
