We are already eating less animal foods since a few years ago, but we are still eating 8-9 billion animals per year.

Keeping some calorie-dense food in your diet-whether it is meat, pasta, beer, or cake-allows you to reach satiety more quickly and easily. And this will keep you from feeling deprived.

Your 'Pringle' contains 30% potato, that yoghurt has the same amount of sugar as ice cream, that whole grain cereal bar may be no better for you than a snickers.

I think people at least now, as opposed to ten-15-20 years ago, kind of get it, what is the bad food. I think, before, there was a time when they didn't even get it that processed food was hurting them. Now, I think they get that, but the big enemies to switching over to good food are convenience.

1 billion people in the world are chronically hungry. 1 billion people are overweight.

Our demand for meat, dairy and refined carbohydrates - the world consumes one billion cans or bottles of Coke a day - our demand for these things, not our need, our want - drives us to consume way more calories than are good for us.

Let me pose you a question. Can farm-raised salmon be organic when its feed has nothing to do with its natural diet, even if the feed itself is supposedly organic, and the fish themselves are packed tightly in pens, swimming in their own filth?
