You should eat from five food groups every day: vegetables, fruits, grains, protein foods, and dairy (or fortified alternatives). These groups, outlined in the USDA’s MyPlate framework, form the foundation of a balanced diet, with oils as a small but important addition. Based on a standard 2,000-calorie diet, here’s what each group looks like in practice and how much you actually need.
Vegetables: 2½ Cups Per Day
Vegetables are the largest section on your plate for good reason. They deliver fiber, potassium, folate, and vitamins A and C with very few calories. The daily target for a 2,000-calorie diet is 2½ cup-equivalents, but variety within the group matters as much as quantity.
Vegetables break down into subgroups, each with its own weekly target. For a 2,000-calorie diet, aim for about 1½ cups of dark greens (spinach, broccoli, kale) per week, 5½ cups of red and orange vegetables (tomatoes, carrots, sweet potatoes, bell peppers), and 5 cups of starchy vegetables (potatoes, corn, green peas). Beans, peas, and lentils have their own subgroup at roughly 1½ cups per week, and they can also count toward your protein intake. The idea is to rotate through these subgroups rather than eating the same two or three vegetables on repeat.
Fruits: 2 Cups Per Day
The daily fruit target is 2 cup-equivalents. Fresh, frozen, and canned fruit all count equally, cup for cup. Dried fruit is more concentrated, so ½ cup of dried fruit equals a full cup. The same applies to 100% fruit juice: ½ cup of juice counts as one cup-equivalent.
That said, whole fruit is the better choice most of the time. It contains more fiber and is more filling than juice, which makes it easier to avoid consuming extra calories. A medium apple, a large banana, or about 8 large strawberries each count as roughly one cup.
Grains: 6 Ounce-Equivalents Per Day
Grains include everything from bread, rice, and pasta to oatmeal, tortillas, and cereals. The daily recommendation is 6 ounce-equivalents, and at least half of those should be whole grains. That means 3 or more ounce-equivalents from sources like whole wheat bread, brown rice, quinoa, or oatmeal, with the remainder from refined grains.
One ounce-equivalent is roughly one slice of bread, one cup of ready-to-eat cereal, or ½ cup of cooked rice, pasta, or oatmeal. Whole grains retain the bran and germ of the grain kernel, which is where most of the fiber, B vitamins, and minerals live. Refined grains have those layers stripped away during processing. This distinction matters for your fiber intake. Adults need between 22 and 34 grams of fiber per day depending on age and sex, with men generally needing more. Women aged 19 to 30 need about 28 grams; men the same age need roughly 34 grams. Most Americans fall well short of those targets, and choosing whole grains is one of the simplest ways to close the gap.
Protein Foods: 5½ Ounces Per Day
This group covers a wide range: meat, poultry, seafood, eggs, nuts, seeds, and soy products like tofu. The daily goal is 5½ ounce-equivalents, but the real emphasis is on mixing up your sources throughout the week rather than relying on a single type.
Seafood deserves special attention. The recommendation for most adults is about 8 ounces of seafood per week, which provides omega-3 fatty acids that support heart and brain health. One ounce-equivalent of protein equals 1 ounce of cooked meat, poultry, or fish; one egg; ¼ cup of cooked beans; 1 tablespoon of nut butter; or ½ ounce of nuts or seeds. Beans, peas, and lentils pull double duty here, counting toward both the vegetable and protein groups, which makes them especially useful if you eat less meat.
Dairy: 3 Cups Per Day
The daily target is 3 cup-equivalents of dairy or calcium-fortified alternatives. Milk, yogurt, and cheese are the primary sources, and they provide the bulk of calcium in the American diet. About 72% of calcium intake in the U.S. comes from dairy products. One cup of milk (any fat level) contains roughly 275 to 300 milligrams of calcium. An 8-ounce container of plain low-fat yogurt delivers about 415 milligrams.
If you don’t consume dairy, calcium-fortified soy milk is the closest nutritional match, providing about 299 milligrams of calcium per cup. Fortified orange juice, tofu made with calcium sulfate, and certain cereals also contribute, though you’ll need to check labels to confirm amounts. Your body absorbs about 30% of the calcium from dairy and fortified foods, which is already factored into the recommended daily intake levels.
Oils: A Small but Necessary Addition
Oils aren’t technically a food group, but they’re included in dietary recommendations because they supply essential fatty acids and help your body absorb fat-soluble vitamins. The daily allowance for a 2,000-calorie diet is about 27 grams, which works out to roughly 5 to 6 teaspoons.
This includes oils you cook with (olive, canola, avocado) and fats naturally present in foods like nuts, seeds, olives, and fatty fish. Your body needs a type of omega-3 fat called ALA that it can’t produce on its own. The adequate intake for adult men is 1.6 grams per day and 1.1 grams for women. Flaxseed, chia seeds, walnuts, and canola oil are among the richest plant sources.
What to Limit Alongside These Groups
Eating from all five groups daily is only half the equation. The other half is keeping added sugars and saturated fat in check. The CDC recommends that people aged 2 and older limit added sugars to less than 10% of total daily calories. On a 2,000-calorie diet, that means no more than 200 calories, or about 50 grams, from added sugars per day. Sweetened drinks, desserts, and flavored yogurts are the most common sources.
Saturated fat follows a similar 10% ceiling. Choosing lean protein, low-fat dairy, and cooking with unsaturated oils helps you stay within that range without needing to track every gram. The practical takeaway: building your meals around the five food groups in the right proportions naturally limits the less helpful components, because whole vegetables, fruits, grains, and lean proteins simply don’t contain much added sugar or saturated fat to begin with.
