Variety is important because no one food can provide all the nutrients the body needs for health. Try new foods to tantalize your taste and vary your nutrient intake.We can make many possible choices within each food group. Choices may be made to accentuate specific needs like fiber. For example, in the protein-rich meat group, beans are a low fat, high fiber option compared to ground beef. In the fruit group, whole fruit is usually a higher fiber choice than fruit juice. Foods containing important nutrients can help us prevent disease and even restore our health. Striking a balance between foods that promote health and those that may be risky is important for long term well being. Choose foods that are better for your health more often. Without a doubt, fats and cholesterol are the single most important group of nutrients to limit in your diet if you want to reduce your risk of chronic disease. Heart disease and cancer, two of this nations leading killers, are linked to diets high in fat. Other chronic health problems may be exacerbated by high fat diets. Saturated fat, that is, fat that is solid at room temperature, appears to carry the greatest amount of risk.Alcohol is not pictured on the food pyramid, but if it were it would be in the tip of the pyramid. Alcohol has only empty calories in the way that sugar and most fats do. Pregnant women should avoid alcohol beverages. Foods and beverages that are less nutritious do not have to be eliminated but they should be consumed in moderation - saved for special occasions. Making healthy food choices can be the difference between health and disease.II. 10 Tips to Healthy Eating Experts agree the key to healthy eating is the time-tested advice of balance, variety and moderation. In short, that means eating a wide variety of foods without getting too many calories or too much of any one nutrient. These 10 tips can help you follow that advice while still enjoying the foods you eat.1. Eat a variety of nutrient-rich foods. You need more than 40 different nutrients for good health, and no single food supplies them all. Your daily food selection should include bread and other whole-grain products, fruits, vegetables, dairy product and meat, poultry, fish and other protein foods. How much you should eat depends on your calorie needs. Use the Food Guide Pyramid and the Nutrition Facts panel on food labels as handy references.2. Enjoy plenty of whole grains, fruits and vegetables. Surveys show most Americans dont eat enough of these foods. Do you eat 6-11 servings from the bread, rice, cereal and pasta group, 3 of which should be whole grains? Do you eat 2-4 servings of fruit and 3-5 servings of vegetables? If you dont enjoy some of these at first, give them another chance. Look through cookbooks for tasty ways to prepare unfamiliar foods.3. Maintain a healthy weight. The weight thats right for you depends on many factors including your sex, height, age and heredity. Excess body fat increases your chances for high blood pressure, heart disease, stroke, diabetes, some types of cancer and other illnesses. But being too thin can increase your risk for osteoporosis, menstrual irregularities and other health problems. If youre constantly losing and regaining weight, a registered dietitian can help you develop sensible eating habits for successful weight management. Regular exercise is also important to maintaining a healthy weight.4. Eat moderate portions. If you keep portion sizes reasonable, its easier to eat the foods you want and stay healthy. Did you know the recommended serving of cooked meat is 3 ounces, similar in size to a deck of playing cards? A medium piece of fruit is 1 serving and a cup of pasta equals 2 servings. A pint of ice-cream contains 4 servings. Refer to the Food Guide Pyramid for information on recommended serving sizes.5. Eat regular meals. Skipping meals can lead to out-of-control hunger, often resulting in overeating. When youre very hungry, its also tempting to forget about good nutrition. Snacking between meals can help curb hunger, but dont eat so much that your snack becomes an entire meal.6. Reduce, dont eliminate certain foods. Most people eat for pleasure as well as nutrition. If your favorite foods are high in fat, salt or sugar, the key is moderating how much of these foods you eat and how often you eat them.7. Balance your food choices overtime. Not every food has to be “perfect”. When eating a food high in fat, salt or sugar, select other foods that are low in these ingredients. 8. Know your diet pitfalls. To improve your eating habits, you first have to know whats wrong with them. Write down everything you eat for three days. 9. Make changes gradually. Health authorities recommend Americans to consume 30 percent or less of their total daily calories from fat, with 10 percent or less of those calories from saturated fat. Remember, the 30 percent refers to your total fat intake overtime, not single foods or meals. Use the following chart to guide your fat intake.Use the Nutrition Facts panel on the food label to help determine how much fat is in foods. Remember, its the total fat intake overtime thats important. A food high in fat can be part of a healthy diet as long as its balanced with other lower-fat food choices.All fats are a combination of saturated, polyunsaturated and monounsaturated fatty acids. Each of these types of fats have different effects on the body, but all contain nine calories per gram.Blood cholesterol levels are influenced by family history, weight, age, smoking, physical activity and eating habits. Studies have shown that diets which are too high in certain saturated fatty acids and dietary cholesterol can raise blood cholesterol.III. Healthy Eating for LifetimeThe Food Guide Pyramid uide pyramid promotes. Eating the suggested portions from this food group will assure that more than half of our calories comes from complex carbohydrates. Moving up the Pyramid, notice the groups get smaller. Foods represented in these groups are needed in smaller amounts for good health. The tip of the Pyramid is the smallest group and should be eaten from the least: oils, fats and sweets. Choose to eat fruits and vegetables without butter or sauce Serve rice, beans, cereals, pasta, whole grains (e.g., couscous, barley, bulgar, etc.)Choose lean cuts of meat, fish, and skinless turkey and chicken When available, buy low- or reduced-sodium or no-salt-added versions of foods Use these recipe substitutions: Use two egg whites for each whole egg and20.
