Nutrition Library: Nutrition Basics What is a healthy Diet?
To obtain the nutrients and other substances needed for good health, vary the foods you eat. Foods contain combinations of nutrients and other healthful substances. No single food can supply all nutrients in the amounts you need. For example, oranges provide vitamin C but no vitamin B12. Cheese provides vitamin B12 but no vitamin C. To make sure you get all of the nutrients needed for health, choose the recommended number of daily servings from each of the food groups displayed in the Food Guide Pyramid.

Americans do choose a wide variety of foods. However, people often choose higher or lower amounts from some food groups than suggested in the Food Guide Pyramid. The Pyramid shows that foods from the grain products group, along with vegetables and fruits, are the basis of healthful diets. Enjoy meals that have rice, pasta, potatoes, or bread at the center of the plate, accompanied by other vegetables and fruit, and lean and low-fat foods from the other groups. Limit fats and sugars added in food preparation and at the table. Compare the recommended number of servings in box 1 with what you usually eat. You can achieve a healthful, nutritious eating pattern with many combinations of foods from the five major food groups. Choosing a variety of foods within and across food groups improves dietary patterns because foods within the same group have different combinations of nutrients and other beneficial substances. For example, some vegetables and fruits are good sources of vitamin C or vitamin A, while others are high in folate; still others are good sources of calcium or iron. Choosing a variety of foods within each group also helps to make your meals more interesting from day to day.
Some Americans eat vegetarian diets for reasons of culture, belief, or health. Most vegetarians eat milk products and eggs, and as a group, these lacto-ovo-vegetarians enjoy excellent health. Vegetarian diets are consistent with the Dietary Guidelines for Americans and can meet Recommended Dietary Allowances for nutrients. You can get enough protein from a vegetarian diet as long as the variety and amounts of foods consumed are adequate. Meat, fish, and poultry are major contributors of iron, zinc, and B vitamins in most American diets, and vegetarians should pay special attention to these nutrients. Vegans eat only food of plant origin. Because animal products are the only food sources of vitamin B12, vegans must supplement their diets with a source of this vitamin. In addition, vegan diets, particularly those of children, require care to ensure adequacy of vitamin D and calcium, which most Americans obtain from milk products.
Some foods such as grain products, vegetables, and fruits have many nutrients and other healthful substances but are relatively low in calories. Fat and alcohol are high in calories.
Many women and adolescent girls need to eat more calcium-rich foods to get the calcium needed for healthy bones throughout life. By selecting low-fat or fat-free milk products and other low-fat calcium sources, they can obtain adequate calcium and keep fat intake from being too high. Young children, teenage girls, and women of childbearing age should also eat enough iron-rich foods, such as lean meats and whole-grain or enriched white bread, to keep the body's iron stores at adequate levels.
