The problem with nutrient-by-nutrient nutrition science is that it takes the nutrient out the context of the food, the food out of the context of the diet, and the diet out of the context of the lifestyle.

If you like eating meat but want to eat ethically, this is the book for you. From the hard-headed, clear-eyed, and sympathetic perspective of butchers who care deeply about the animals whose parts they sell, the customers who buy their meats, and the pleasures of eating, this book has much to teach. It’s an instant classic, making it clear why meat is part of the food revolution. I see it as the new Bible of meat aficionados and worth reading by all food lovers, meat-eating and not.

BASICS OF DIET AND HEALTH The basic principles of good diets are so simple that I can summarize them in just ten words: eat less, move more, eat lots of fruits and vegetables. For additional clarification, a five-word modifier helps: go easy on junk foods.

Here we have the great irony of modern nutrition: at a time when hundreds of millions of people do not have enough to eat, hundreds of millions more are eating too much and are overweight or obese.

The standard four food groups are based on American agricultural lobbies. Why do we have a milk group? Because we have a National Dairy Council. Why do we have a meat group? Because we have an extremely powerful meat lobby.

I would require every producer of food to follow and have enforced a standard safety plan. We know how to produce safe food. It has a horrible name; it's called HACCP - Hazard Analysis and Critical Control Point - and this was a food safety system that was developed for NASA so that astronauts wouldn't get sick in outer space. If you just think about what it might be like to have food poison under conditions of zero gravity, you don't even want to think about it.

You need to identify the steps at which contamination can occur - those are the critical control points. You take steps to make sure that that doesn't happen. And you monitor and evaluate and test to make sure that your system is working properly. And if it's done diligently and done faithfully and monitored carefully, then they're producing safe food. And no astronaut of which I'm aware has ever gotten food poisoning in outer space.
