So I decided to take the doctors up on the challenge. I set out to collect and formulate some straightforward, memorable, everyday rules for eating, a set of personal policies that would, taken together or even separately, nudge people onto a healthier and happier path. I solicited rules from doctors, scientist, chefs, and readers, and then wrote a bunch myself, trying to boil down into everyday language what we really know about healthy eating. And while most of the rules are backed by science, they are not framed in the vocabulary of science but rather culture -- a source of wisdom about eating that turns out to have as much, if not more, to teach us than nutritional science does. What follows is a small sample of "Food Rules", a half dozen policies that will give you a taste of what you'll find in the book: sixty-four food rules, each with a paragraph of explanation. I think you'll see from this little appetizer that "Food Rules" is a most unconventional diet book. You can read it in an hour and it just might change your eating life. I hope you'll take away something you can put to good use, and maybe get a chuckle or two along the way. And do let me know if have any food rules I should know about. I'm still collecting them, at email@example.com.
#3 Avoid food products containing ingredients that no ordinary human would keep in the pantry.
Ethoxylated diglycerides? Cellulose? Xanthan gum? Calcium propionate? Ammonium sulfate? If you wouldn't cook with them yourself, why let others use these ingredients to cook for you? The food scientists' chemistry set is designed to extend shelf life, make old food look fresher and more appetizing than it really is, and get you to eat more. Whether or not any of these additives pose a proven hazard to your health, many of them haven't been eaten by humans for very long, so they are best avoided.
#19 If it came from a plant, eat it; if it was made in a plant, don't.
#36 Don't eat breakfast cereals that change the color of the milk.
This should go without saying. Such cereals are highly processed and full of refined carbohydrates as well as chemical additives.
#39 Eat all the junk food you want as long as you cook it yourself.
There is nothing wrong with eating sweets, fried foods, pastries, even drinking soda every now and then, but food manufacturers have made eating these formerly expensive and hard-to-make treats so cheap and easy that we're eating them every day. The french fry did not become America's most popular vegetable until industry took over the jobs of washing, peeling, cutting, and frying the potatoes—and cleaning up the mess. If you made all the french fries you ate, you would eat them much less often, if only because they're so much work. The same holds true for fried chicken, chips, cakes, pies, and ice cream. Enjoy these treats as often as you're willing to prepare them—chances are good it won't be every day.
#47 Eat when you are hungry, not when you are bored.
For many of us, eating has surprisingly little to do with hunger. We eat out of boredom, for entertainment, to comfort or reward ourselves. Try to be aware of why you're eating, and ask yourself if you're really hungry—before you eat and then again along the way. (One old wive's test: If you're not hungry enough to eat an apple, then you're not hungry.) Food is a costly antidepressant.
#58 Do all your eating at a table.
