How do I know if my baby is sensitive to foods?

According to most of the research I have done, most babies are not really affected by what their mother eats. Do you find this to be true? I get a little nervous lately about tomatoes, onions, beans, spicy foods, etc.  Because my LO has been very fussy. But to be perfectly honest, I think she may just be a fussy baby. So is there a way to differentiate between what you are eating causing an effect and just normal baby fussiness? Thanks.
