I have some pretty severe food allergies. And I'm picky. I'm very limited in what I can eat. I have severe allergies to wheat, gluten, beef (WTF?), yeast and all dairy. I am also allergic to all nuts, all seafood, lettuce, mushrooms, sugar, coffee, etc. The full list is way too long to post. I usually do OK eating beef in small quantities, like in chili or tacos. I cannot eat steak though :( I can usually eat gluten in small quantities too, but I try to avoid it since it makes me feel bloated and icky. Dairy really does a number on my stomach! I won't go into detail (YOU'RE WELCOME!) but I try not to eat anything that has milk or eggs in it. I do use cheese while cooking occasionally, I just love it so much.
