There are two prominent arguments when it comes explaining the recent spike in food intolerances. First, we're better at recognizing food intolerance (whereas in the past, it would have been thrown out as irritable bowel syndrome or just an upset tummy). And second, foods have been so corrupted through genetic modification that our bodies reject them.
Now, there's a third possible explanation: Bisphenol A (BPA). Found in plastic and aluminum food containers, BPA is already implicated in a laundry list of crimes, but now research published in the Federation of American Societies for Experimental Biology (FASEB) Journal found that it might be at the root of food intolerance.
In an animal study, the researchers found that mice exposed to BPA as pups (infant mice) until they were weaned demonstrated an exacerbated immune response to a new food protein. Continuing to eat the food protein resulted in chronic inflammation, which is an indication of a food intolerance that was not observed in animals who weren't exposed to BPA.

Gerald Weissmann, MD, editor-in-chief of The FASEB Journal responded to the study, saying, "We may look back one day and see BPA exposure as one of the more important public health problems of our time."
Since the experiment was conducted on mice (as it would be unethical to do such a test on humans), how much BPA exposure required to give a human food intolerance isn't known. But infants are a vulnerable group so not only is it important to watch out for BPA in your baby's food, breastfeeding moms should also be careful to limit their own BPA exposure as BPA has been found in breast milk.
