Yeah, to be honest there really is no consensus about this within vegan communities. I would say from an ethical stand point, the biggest thing would be if a company is continually abusing animals in their processes. And animal testing is a difficult subject too, because virtually every food has been subjected to animal testing.
I do think it’s also worth mentioning that plants really are perfectly fine to center a diet around, in and of themselves. I had a really difficult time transitioning to a plant-based diet because addiction is in my genes. But at the same time I was at a place in my life where my health was declining fast, I felt like shit all the time, and I was having to force myself to eat every day. I hated food. But after I got used to eating 100% plants, all of that completely changed. I felt better than I ever had. My arthritis-like symptoms (and other inflammatory problems) completely vanished. I had all kinds of energy that I never used to. And as I got better at cooking plant based and found good places to eat, I actually fell in love with food again. Plants are fucking great.
