Absolutely, our genetics play a huge role, as do environmental factors, our gut biome, what our body has adapted to through our lifetime, etc. My "vegan activism" really only goes as far as cooking tons of delicious vegan food for people, answering questions, and calling BS on unfounded claims. In reality, I speak/write a lot more mindful eating, the need for each of us to really explore what our bodies need.

I don't make it a habit of challenging or debating people about veganism; my issue in this particular case was the lack of evidence, research, science to back up the sweeping claims being made.

Thanks for dropping in with a thoughtful comment :-)
