Turn on your TV, open a newspaper, or boot up your computer and you're bound to get some confusing news about diet and health. Don't let it drive you to distraction or to the donut shop. Instead, remember four key facts:
1. What you eat affects your appearance, your energy and comfort, and—above all your health.
2. America is on the wrong track. Two out of every three of us are overweight or obese. Diabetes and high blood pressure are on the rise. Heart attacks, strokes, and cancer are distressingly common. Many factors contribute to these complex problems, but the basic reasons are simple: we eat too much, we choose the wrong foods, and we don't get enough exercise.
3. Scientists know what diet is best for health (see below). The fine print has changed and is likely to change some more, but the key facts are in.
4. Good eating is not a punishment, but an opportunity. If you know why it's important and what to do, you'll find it enjoyable and satisfying. And if you establish an overall pattern of healthful nutrition, you'll have plenty of wiggle room to savor the treats that matter most to you.
