So this guy says a vegetarian diet is probably healthier than a meat diet. Big surprise there. Hope he liked all the funding he received. Like everything else, you can not drink gallons of whole milk every day, just like you can't eat red meat every meal. Moderation.
We are nothing more than hunter-gatherers: more plants/berries, less meats, water by the gallon, plenty of exercise. Deviate too far from any of that and you run the risk of not being healthy.
