While we get a lot of advice about what to eat, what people need to hear is actually quite simple.
The New York Times asked me, among others, to contribute to its Room for Debate blog on the question of whether anyone could possibly need to hear one more word about what constitutes a healthful diet. Here's my two-cents' worth:
Better Information and Better Options
Of course Americans need more information about eating well. Otherwise we wouldn't have an obesity problem. In my daily teaching and contact with the public, I hear endless confusion about what to eat.
People are bombarded with conflicting advice, much of it from sources with a vested interest in selling particular foods, supplements or diet plans. Nutrition studies tend to focus on single nutrients, making their results difficult to apply to real diets. No wonder people have a hard time knowing what or whom to believe.
This is too bad, really. The basic principles of healthy eating could not be easier to understand: eat plenty of vegetables and fruits, balance calorie intake with expenditure, and don't eat too much junk food.
If such principles seem hard to follow, it is surely because of how they affect the food industry. Balancing calorie intake often means eating less, but doing so is bad for business. Food companies must do everything they can to sell more food, not less.
