I am actually not vegan, I eat fish.
I have always had an issue with animal cruelty and cringe every time I see one of those trucks loaded with cows. I have seen how animals are treated, it has turned my stomach and to be honest I think I should have stopped eating meat because of those practices BUT I didn't. My reason to cut out animal products were purely health related. So unlike others here who have clear convictions that I admire, mine was purely about my health, so kinda selfish
You don't believe that animal products have much to do with increase in heart disease, cancer and other diseases? There is plenty of evidence and scientific evidence that proves it beyond a shadow of a doubt (in my opinion) but I agree with you that probably everything in moderation should be fine if you are a moderately healthy individual who is not battling any kind of disease. Whereas eliminating animal products from my diet has made a HUGE difference in my health, I agree that everyone is different and that it may not work for everyone.
I am not sure that I would agree on the "predisposition" to disease. I don't remember where I read it but it really stuck in my mind "If xyz disease runs in your family, you don't need to run with it". I guess the question is, are those diseases really genetically predispositioned OR are they in fact a lifestyle or eating pattern that we adopt while we grow up?
But back to your question, I have slowly started to eliminate or at least cut down on things that are leather, animal hair, etc. but I am not very consistent - unfortunately, I wish I could say otherwise. What can I say, I am far from perfect!!
It's not easy, my dogs eat raw meat, my kids still eat eggs and some dairy as well as fish, so I am not exactly an example of truly vegan lifestyle.
