I think reaction to food can vary greatly from individual to individual, so maybe a broad generalization doesn't make sense. Or rather it makes sense to determine individual problems, rather than broad common problems. Supposedly they could have created a similar study by just testing a single problematic food item (I don't know, wheat or whatever), and they should also have found an effect - only smaller. It does not seem to outlandish that different things can trigger allergies, yet all allergic reactions are somewhat similar.
