The average vegan
Initial assumptions suggest that ethical reasons play a more significant role than health and ecological motives. That assumption is so far coherent with the vegans I know personally.
For most people, the decision to eat vegan is a combination of different reasons and influences.
If you’re considering transitioning to a vegan diet, you should find out which reasons appeal most to you. According to that, you might have an easier time switching and prioritising what is important to you.
