If you think food that tastes good can't possibly be good for you, or if you feel guilty about enjoying a meal, it might be time to hit the reset button on your attitudes toward eating and nutrition.

Once you start worrying about what you need to avoid at every meal, food can morph from enjoyment to enemy.

If you're worried about high blood pressure, a new systematic review of scientific evidence has good news: Changing your diet really can make a difference. Not surprisingly, the most effective diet for reducing hypertension was one designed specifically for that purpose - the Dietary Approaches to Stop Hypertension (DASH) plan.

Have you ever looked at a "sell by" or "best if used by" date on a food container, checked the calendar, and thrown out something because it had "expired"? Youre part of a $165 billion a year problem. About 40% of Americas food gets wasted, much of it because of a confusing patchwork of state laws that make people think food thats still safe to eat should be trashed.

Water makes up most of your body, ranging from about 75% of body weight in infancy to 55% of body weight at older ages.

As a cardiologist, public-health advocate and nutrition scientist, I see a lot of good in the DGAs. First, the DGAs emphasize healthful eating patterns and foods. This is an advance over past guidelines, which focused more on isolated nutrient targets.

Every five years, your Uncle Sam rounds up the latest scientific evidence about nutrition and serves up advice about what to eat and drink for better health. The resulting Dietary Guidelines for Americans (DGA) - whose eighth edition was released in January - provides basic guidance to the American public about healthy eating patterns and shapes nutrition education programs.

When it comes to planning your meals, it's hard to beat seafood as a nutritional powerhouse. Seafood is rich in protein and other important nutrients. Prepared right - without frying, breading, tubs of butter or caloric sauces - it delivers these nutritional benefits without a lot of calories. Many varieties also contain heart-healthy omega-3 fatty acids.

When the supermarket fish counter fails you, dont hesitate to head for the canned-fish aisle. Canned sardines and salmon are generally sustainable choices; canned tuna, while controversial, typically includes sustainable pole-caught albacore or skipjack varieties.

There's good news at your local grocery store. "You should walk into a supermarket with a very positive attitude," says Alice H. Lichtenstein, DSc, director of Tufts' HNRCA Cardiovascular Nutrition Laboratory and executive editor of the Tufts Health & Nutrition Letter.
