I have been through all different stages meat, fowl and fish only, fish only, vegetarian and vegan. I do care about animals and wish to minimise their suffering. But I also care about if I feel healthy. Supplements didn't do the trick for me. Nowadays back to fish and eggs at least once a week and feeling much better. If we'd all seriously limit our meat/fowl/fish consumption we'd already be making a big advance towards reducing animal suffering. BTW plants are living too. There is no way to avoid some kind of suffering. So we have to make a compromise. Existence is a strange thing. Continue exploring what feels good for you, but don't start to suffer because you wish to reduce suffering :)
