I am vegetarian, have been since a student, many years ago.
cheese except Edam and others made with oil, are off limits because the vast majority of cheese is made with animal rennet - vegetable rennet is still a minority, niche market, microbial rennet uses the genes of an animal, and yet most of the world still doesn’t require vegetarian items to be labelled, hoping that has changed now!
Cheese also uses milk as an ingredient, which as we all know, cows are on running machines these days, not forgetting the anti biotics that are given
to the cows for a variety of reasons, one to keep them lactating.
I do not wear leather shoes, sit on a leather sofa, have leather clothing or accessories due to where leather comes from.
Eggs are also off limits to me, due to the environment that commercial hens live in, I eat eggs from the chickens in my back garden though.
im not a vegan, but over the years have worked out what to buy and what not to buy.
stork margarine to have fish oil in, I really don’t like the thought of killing the fish in my aquarium so I can eat abit of marg!
also washing powders etc is ecover in our house.
I personally don’t agree with any form of animal products in commercial vegetarian/vegan food, because I don’t feel comfortable with some animal husbandry in farming
