I was on Today With Seán O’Rourke last Monday,
talking about veganism. I explained that I’m happy for people to eat whatever diet they like provided they don’t object to mine, but that I’m deeply sceptical about veganism’s claims to sustainability. I also pointed out that we have evolved to eat meat and plants – just consider our teeth and digestive system. I didn’t have time to challenge the claim that a vegan diet is complete. It isn’t. Vegans have to take a vitamin B12 supplement.
