Adequate carbohydrates

At least 100 grams of carbohydrates per day are needed to prevent fatigue and dangerous fluid imbalances. To make sure you get enough carbohydrates, eat 6-11 servings (see Figure 2) from the Bread, Cereal, Rice, and Pasta Group on the Food Guide Pyramid every day.

A daily fiber intake of 20 to 30 grams. Adequate fiber helps with proper bowel function. If you were to eat 1 cup of bran cereal, 1/2 cup of carrots, 1/2 cup of kidney beans, a medium-sized pear, and a medium-sized apple together in 1 day, you would get about 30 grams of fiber.



No more than 30 percent of calories, on average, from fat per day, with less than 10 percent of calories from saturated fat (such as fat from meat, butter, and eggs). Limiting fat to these levels reduces your risk for heart disease and may help you lose weight. In addition, you should limit the amount of cholesterol in your diet. Cholesterol is a fat-like substance found in animal products such as meat and eggs. Your diet should include no more than 300 milligrams of cholesterol per day (one egg contains about 215 milligrams of cholesterol, and 3.5 ounces of cooked hamburger contain 100 milligrams of cholesterol).

At least 8 to 10 glasses, 8 ounces each, of water or water-based beverages, per day. You need more water if you exercise a lot.

These nutrients should come from a variety of low-calorie, nutrient-rich foods. One way to get variety -- and with it, an enjoyable and nutritious diet -- is to choose foods each day from the Food Guide Pyramid (see Figure 1).
