问题     For more than a decade, dieticians and nutritionists harangue us to lower the amount of fat in our diet. As it happens, their message is only partly correct. Although all fats are high in calories, certain fats, like the omega-3 fatty acids commonly found in fish, are actually good for us, provided we consume them in moderation. Not only do ome-ga-3s reduce the risk of clot formation in blood vessels, they also lower the amount of triglycerides, another fatty substance in the blood. The bottom line is that people who eat 6 to 8 ounces of fatty fish a week experience significantly fewer heart attacks and strokes.
    Still on the consume-sparing lists are saturated fats, commonly found in red meats and whole-milk dairy products. Recent studies also suggest that another group of fats, called trans-fatty acids, found in abundance in crackers and cookies prepared with hydrogenated oils, may be an even more dangerous promoter(引发物)of high cholesterol than saturated fats.
    The most immediate benefit from adopting a healthy diet is that it can lower blood pressure. Even if you don’t have hypertension, decreasing your blood pressure makes your blood vessel springier(有弹性的)and can help stabilize potentially dangerous plaques in the arteries. Two major studies have shown that DASH(Dietary Approaches to Stopping Hypertension)diet, which emphasizes fruits and vegetables, promotes low-fat dairy and high-fiber grains, permits modest portions of lean meat and reduces sodium intake, can lower blood pressure as effectively as taking medicine. Just as important, the foods taste good and aren’t too different from what most Americans are used to eating.
