Optional: Alcohol in Moderation (Not for Everyone)

Scores of studies suggest that having an alcoholic drink a day lowers the risk of heart disease. Moderation is clearly important, since alcohol has risks as well as benefits. For men, a good balance point is one to two drinks a day; in general, however, the risks of drinking, even in moderation, exceed benefits until middle age. For women, it's at most one drink a day; women should avoid alcohol during pregnancy.Forget about Numbers and Focus on QualityYou'll notice that the Healthy Eating Pyramid does not give specific advice about the numbers of cups or ounces to have each day of specific foods. That's because it's not meant to be a rigid road map, and the amounts can vary depending on your body size and physical activity. It's a simple, general, flexible guide to how you should eat when you eat.There's just one basic guideline to remember: A healthy diet includes more foods from the base of the pyramid than from the higher levels of the pyramid. Within this guideline, however, there's plenty of flexibility for different styles of eating and different food choices. A vegetarian can follow the Healthy Eating Pyramid by emphasizing nuts, beans, and other plant sources of protein, and choosing non-dairy sources of calcium and vitamin D; someone who eats animal products can choose fish or chicken for protein, with occasional red meat.Choosing a variety of fresh, whole foods from all the food groups below the "Use Sparingly" category in the Healthy Eating Pyramid will ensure that you get the nutrients you need. It will also dramatically lower your salt intake, since most of the salt in the U.S. diet lurks in processed food—canned soups, frozen dinners, deli meats, snack chips, and the like.Perhaps the only foods that are truly off-limits are foods that contain trans fat from partially hydrogenated oils. Luckily, in the U.S. and Canada, trans fats must be listed on nutrition labels. More and more food manufacturers, restaurants, and even entire communities are going trans fat-free, making it easier to avoid this health-damaging type of fat.

Other Alternatives

The Healthy Eating Pyramid summarizes the best dietary information available today. It isn't set in stone, though, because nutrition researchers will undoubtedly turn up new information in the years ahead. The Healthy Eating Pyramid will change to reflect important new evidence.This isn't the only alternative to the USDA's MyPyramid. The Asian, Latin, Mediterranean, and vegetarian pyramids promoted by Oldways Preservation and Exchange Trust are also good, evidence-based guides for healthy eating. The Healthy Eating Pyramid takes advantage of even more extensive research and offers a broader guide that is not based on a specific culture.Failing the TestBack in the 1990s, the USDA's Center for Nutrition Policy and Promotion created the Healthy Eating Index "to measure how well American diets conform to recommended healthy eating patterns." (3) In its original form, this score sheet used five elements from the longstanding USDA Food Guide Pyramid (number of daily servings of grains, vegetables, fruits, meat, and dairy products) and five from the 1995 Dietary Guidelines for Americans (total fat in the diet, percentage of calories from saturated fat, cholesterol intake, sodium intake, and variety of the diet). A score of 100 meant following the federal recommendations to the letter while a score of 0 meant totally ignoring them.
(The USDA has since updated the score sheet to reflect the Dietary Guidelines for Americans 2005.)To see how well the principles embodied in the Healthy Eating Pyramid stacked up against the government's advice, Harvard School of Public Health researchers created an Alternate Healthy Eating Index with a scoring system similar to the USDA's index. They then compared the two indexes, using information about daily diets collected from more than 100,000 female nurses and male health professionals taking part in two long-term studies.Men who scored highest on the USDA's original Healthy Eating Index (meaning their diets most closely followed federal recommendations) reduced their overall risk of developing heart disease, cancer, or other chronic disease by 11 percent over 8 to 12 years of follow-up compared to those who scored lowest. Women who most closely followed the government's recommendations were only 3 percent less likely to have developed a chronic disease. (4)In comparison, scores on the Alternate Healthy Eating Index did appear to correlate more closely with disease in both sexes. Men with high scores (those whose diets most closely followed the guidelines in the Healthy Eating Pyramid) were 20 percent less likely to have developed a major chronic disease than those with low scores. Women with high scores lowered their overall risk by 11 percent. Men whose diets most closely followed the Healthy Eating Pyramid lowered their risk of cardiovascular disease by almost 40 percent; women with high scores lowered their risk by almost 30 percent."The new USDA dietary pyramid is a lost opportunity to help Americans make informed choices about diet and long-term health," says Dr. Willett. "It's clear that we need to rebuild the pyramid from the ground up, not just tip it on its side and dress it up with new colors. Every one deserves it
So please take a good care about yourself
god bless
