You learn about the five food groups when you’re a child, but you probably haven’t thought about them much since then. While adults are concerned with counting calories and calculating fat, the USDA website wants to help you remember the importance of these distinct groups:
1. Vegetables. Vegetables and 100% vegetable juices all count as members of the vegetable group. While the amount you should consume each day varies from person to person, generally half of your plate should be covered by veggies.
2. Fruits. Whether you eat whole fruits or you enjoy them pureed, dried, or blended, fruits are another necessary food group. Women and men over the age of 19 should consume between 1 1/2 to 2 cups of fruit per day, depending on an individual’s age and weight.
3. Grains. Examples of healthy grains include whole-wheat flour, cracked wheat, oatmeal, whole cornmeal, and brown rice. At least half of your grains should be whole grains, and the recommended daily amount for a person over 19 is between 5 and 8 ounces.
4. Proteins. Proteins are meats like chicken or beef, but they also include meatless foods like beans, peas, eggs, and processed soy products like tofu, nuts, and seeds. The amount of protein you need depends on your age, physical activity, and other factors.
5. Dairy. Dairy includes calcium-rich foods like milk and cheese, and only low-fat or fat-free varieties are usually recommended.
