I particularly liked that he cited a lot of studies and explained why doctors like to see the progression from mouse studies through all levels of human trials. That helped me to understand why nutrition advice is so generic. At the same time he gives mouse work and population studies where people actually eat the food. This allowed me to feel that since it's already consumed those middle trials don't have to be run (and since there is no pharma money they won't be) and, for me, I feel comfortable that these dietary changes at least allow me to feel like I'm doing something proactive.
