I am thinking of becoming a vegetarian. Are you vegetarian?
Yes, I do not eat meat or the by-products of animal slaughter.
So are you a vegan? I'm not for sure what the difference is in veganism and vegetarianism.
Vegans don't use any animal products. 
Oh that would be more difficult. My dad has alph-gal and he has to avoid mammal products. They are hid in so many foods.
Packaged and processed foods, such as cakes, cookies, candies, chocolate, yogurt, and marshmallows, often contain unfamiliar animal ingredients, and so may be a special concern for vegetarians due to the likelihood of such additives. Feelings among vegetarians may vary concerning these ingredients. Some vegetarians scrutinize product labels for animal-derived ingredients while others do not object to consuming cheese made with animal-derived rennet. Some vegetarians are unaware of animal-derived rennet being used in the production of cheese.
