The first version had terrible narration, completely monotone. This narrator is much better but the author should stick to what he knows and not try and teach us about nutrition instead he should just go over the basics and recommend an author who actually knows what he’s talking about. He often contradicts himself. For instance, he says we should get our vitamins from food and then goes on to talk about how we need folic acid. So clearly he doesn’t know that folic acid does not occur in food it’s entirely synthetic only comes in fortified Foods and cheap vitamins. Folate is the naturally occurring version and the one used in premium supplements. Moreover 30 to 40% of the population I am one of them have a mutated Gene that prevents them from processing folic acid properly and it can build up in your system. So get your biology advice from an actual expert
