Not a vegan either, but I am allergic to dairy (not just lactose intolerant). If you are looking for vegan cheese replaceements, the VioLife cheese brand is AAHHHHH-mazing. Their feta tastes so good! Their cheddar and mozzarella aren't quite as authentic tasting, but are by far the best that I've tasted, especially compared to Daiya, which is horrible to me. VioLife cheeses made with nuts though, which can be problematic for some. Available at Whole Foods.
Reading this as I am gorging myself with moz cheeze that I dowsed in balsamic LOL It came in my hello fresh box that was supposed to make caprese sandwiches for lunch. Thank you 20 year olds at work for getting me hooked on hello fresh LOL. Well now I don't have lunch cause I just ate all the cheese.
A friend of mine is allergic to dairy. For a while I thought he was full of it. But then I witnessed him having full on anaphylaxis one night at dinner. It was at a mutual friend's restaurant, who admitted to using the same utensils to make his food as he did to slice up cheese for another order. I guess nobody really believed that someone could be actually allergic to dairy. I had melt in your mouth benadryl strips that got him to the hospital (the hospital was down the street and his gf got him into the car to drive him...not a good idea, but I had no say in that). The ordeal was scary.
He can actually put absolutely FRESH cream in his coffee. But once it is not so fresh...even a few days old, is where he has the problem. I think I remember him saying something about the fermentation. He can't, under any circumstances have cheese or yogurt.
My favorite foods are cheese and shellfish. If I was allergic, I'd prep myself with benadryl and steroids and have a feast in the car outside of the emergency room LOL. I can't imagine being allergic to foods.
