...truth is that nutritionists have a fairly good idea about what constitutes a healthy diet as well as plenty of solid evidence to back that up. As a rule, they tell us, we should eat lots of fruits and vegetables, favor whole grains over highly processed cereals and make red meat an occasional treat rather than the daily centerpiece of our evening meal. And we shouldn't eat any more than our body needs...
...rewards are worth the effort. Studies show that as much as 80% of heart disease and 90% of diabetes can be tied to unhealthy eating and lifestyle habits. Doctors have proved that a diet emphasizing fruits and vegetables as well as small amounts of nuts and dairy products can lower blood pressure and "bad" cholesterol as effectively as many medications. And evidence is growing that adding fiber to your diet and avoiding highly refined foods can help prevent or delay the onset of Type 2 diabetes...
Good fats do more than help protect the heart. They also seem to delay hunger pangs. "People on these high-starch, low-fat diets are often hungry soon after they eat.

"And longer-term studies are showing that people tend to be able to control their weight better over the long run on a moderate or higher...

What about the Mediterranean diet? you ask. Researchers have long been fascinated by the traditional Greek and Italian diets of the 1960s, which contained as much as 40% fat but didn't trigger a lot of heart attacks. Don't assume that what worked for Greeks and Italians 40 years ago will work for you. After all, they typically ate a pound of fruit a day (equal to four medium apples) and little red meat, and many of them got lots of exercise tilling fields and tending livestock. "The Mediterranean diet works well in the Mediterranean," says Yale's Katz...
