I have some pretty weird food allergies – carrots and watermelon (actually I’m pretty sure all melons – I don’t really care for them anyway, but I do have a reaction whenever they are mixed into fruit salad.) I just avoid these foods at all costs, especially carrots as they make my throat swell up if I eat enough of them. You never realize how much a particular ingredient is used until you become allergic and have to check EVERYTHING. Carrots are used as a filler in A LOT of different foods – so I just check the ingredients of anything new I try. Try being a vegetarian and going to salad bars, then seeing they use pre packaged mixes that already have carrots in them. They are in a lot of vegetarian foods, some drinks listed as FRUIT juice, and they even use carrots in some energy gels – I’m telling you they show up in the weirdest places!
