We are not only what we eat, but how we eat, too.

I think that the American diet is a very large part of the reason we're spending 2.3 trillion dollar per year on health care in this country. 75% of that money goes to treat chronic diseases, preventable chronic diseases, most of those are linked to diet.

Once you introduce the issue to young people and suggest to them that they have the ability to vote with their forks, either by positively going for certain kinds of foods or rejecting other kinds of foods, they realize that this is a responsibility and an opportunity to shape the world a little bit by their own choices.

The sheer novelty and glamor of the Western diet, with its seventeen thousand new food products every year and the marketing power - thirty-two billion dollars a year - used to sell us those products, has overwhelmed the force of tradition and left us where we now find ourselves: relying on science and journalism and government and marketing to help us decide what to eat.

We are becoming a nation of orthorexics: people with an unhealthy obsession with healthy eating.
