Do you have food allergies?
SE is chock full of glorious food, photos, recipes and lively discussion about all the above. I know food allergies are very common, whether it's gluten sensitivity, lactose intolerance, anaphilactic shock from a peanut butter sandwich, etc.
What foods are you allergic to? Are they life-threatening allergies, or slight ones that allow you to indulge in said food regardless, only to suffer mild disomfort later?
