Up until Prohibition, an apple grown in America was far less likely to be eaten than to wind up in a barrel of cider. ("Hard" cider is a twentieth-century term, redundant before then since virtually all cider was hard until modern refrigeration allowed people to keep sweet cider sweet.)

There are many people who don't do well on a vegetarian or vegan diet, that for them, meat is a very nutritious food. So, I'm not prepared to give up meat. I don't think we need to give up meat, but we certainly need to change the way we raise meat and diminish the amount of it in our diet.

A vegan in a Hummer has a lighter carbon footprint than a beef eater in a Prius.

Wrangham cites several studies indicating that in fact humans don't do well on raw food: they can't maintain their body weight, and half of the women on a raw-food regimen stop menstruating. Devotees of raw food rely heavily on juicers and blenders, because otherwise they would have to spend as much time chewing as the chimps do. It is difficult, if not impossible, to extract sufficient energy from unprocessed plant matter to power a body with such a big, hungry brain.

Another day it occurred to me that time as we know it doesn't exist in a lawn, since grass never dies or is allowed to flower and set seed. Lawns are nature purged of sex or death. No wonder Americans like them so much.

Don't eat anything your great-great grandmother wouldn't recognize as food. There are a great many food-like items in the supermarket your ancestors wouldn't recognize as food.. stay away from these

Cooking for yourself is the only sure way to take back control of your diet from the food scientists and food processors, and to guarantee you're eating real food rather than edible foodlike substances, with their unhealthy oils, high-fructose corn syrup, and surfeit of salt.
