I used to have these for breakfast before having a baby

Would mentally prepare me for the day so I didjt binge eat my weight is getting out of control. Now I wouldn't limit myself to eating healthy foods but when I need a kick start I have these but it says to speak to a doctor if breastfeeding is that becuase someone may have them and restrict themselves or is there something in there that I cant have while breast feeding.

I dont have the time or money for fresh fruit ones daily plus I really like these
