The short answer
A balanced diet is built mostly from nutrient-dense, minimally processed foods: protein foods, dairy, vegetables, fruits, healthy fats and whole grains. It keeps highly processed foods, added sugars, refined carbohydrates and alcohol low, and it gives you the right amount of energy for your age, sex, size and activity level. No single food is required, and no single meal makes or breaks it. What counts is the pattern over days and weeks.
The food groups
For years, the USDA's MyPlate graphic organized healthy eating into five food groups: fruits, vegetables, grains, protein foods and dairy. The 2025–2030 Dietary Guidelines, published in January 2026, present their advice as a food pyramid instead, but the building blocks are much the same. Here are the daily serving goals they give for a 2,000-calorie pattern, to be adjusted for your own calorie needs:
| Food group | Daily goal (2,000 calories) | What the guidelines emphasize |
|---|---|---|
| Vegetables | 3 servings | A variety of colors, eaten whole; frozen or canned with little or no added sugar are fine |
| Fruits | 2 servings | Whole fruit; limit juice or dilute it with water |
| Whole grains | 2–4 servings | Fiber-rich whole grains; cut back on refined grains like white bread and crackers |
| Dairy | 3 servings | Dairy with no added sugars; the guidelines include full-fat dairy |
| Protein foods | 1.2–1.6 g protein per kg of body weight | A variety of eggs, poultry, seafood, meat, beans, peas, lentils, nuts, seeds and soy |
For protein, the guidelines give a target in grams rather than servings: 1.2 to 1.6 grams per kilogram of body weight per day. For someone who weighs 70 kg (about 154 lb), that's 84 to 112 grams a day. The protein calculator works this out for you.
Healthy fats, in sensible amounts
Fat is part of a balanced diet. The guidelines point to fats that come in whole foods, such as seafood rich in omega-3s, nuts, seeds, olives, avocados, eggs, meat and dairy, and they name olive oil as an oil to prioritize for cooking. They keep the long-standing limit on saturated fat: in general, no more than 10% of daily calories. On 2,000 calories, that's under about 22 grams; the saturated fat calculator works it out for any calorie level. For more on the different fats, see saturated vs unsaturated fat.
What to limit
- Highly processed foods. The guidelines advise avoiding highly processed salty or sweet packaged foods, such as chips, cookies and candy, and favoring home-prepared meals.
- Added sugars. No amount of added sugar is recommended, and one meal should contain no more than 10 grams. Sugar-sweetened drinks such as soda, fruit drinks and energy drinks are best avoided.
- Refined carbohydrates. Swap white bread, packaged breakfast foods, flour tortillas and crackers for whole-grain options where you can.
- Sodium. Under 2,300 mg a day for anyone 14 and older, and less for younger children.
- Alcohol. The guidelines say to consume less alcohol for better overall health, and some people, including pregnant women, should avoid it entirely.
Eat the right amount for you
Balance is also about quantity. The calories you need depend on your age, sex, height, weight and activity level, so there's no single right number. Paying attention to portion sizes, especially of high-calorie foods and drinks, helps. To estimate your own needs, try the calorie calculator or the TDEE calculator, which shows maintenance calories at every activity level.
The guidelines also count drinks. Water, still or sparkling, and unsweetened drinks are the recommended choices.
How the calories usually split
Another way to describe balance is by macronutrients. The National Academies' Acceptable Macronutrient Distribution Ranges for adults are 45–65% of calories from carbohydrate, 20–35% from fat and 10–35% from protein. Those wide ranges show how many different eating patterns can be healthy. Read more in what are macros.
What a balanced plate can look like
You don't need to count servings at every meal. A simple approach is to build each meal around a protein food, add vegetables or fruit, and include a whole grain or other fiber-rich carbohydrate, with some healthy fat for cooking or flavor. For example:
- Breakfast: eggs or plain yogurt, a piece of fruit and whole-grain toast or oatmeal.
- Lunch: beans or chicken over a big salad with olive oil, and a whole-grain roll.
- Dinner: baked or grilled fish, roasted vegetables and brown rice.
- Snacks: nuts, fruit, cheese or plain yogurt.
Cooking methods matter too: the guidelines suggest baking, broiling, roasting, stir-frying or grilling in place of deep frying.
When you need different advice
The Dietary Guidelines have separate advice for infants and children, teenagers, pregnant and breastfeeding women, older adults, vegetarians and vegans, and people with chronic disease. If you have a health condition, take medication that interacts with food, or are trying to change your weight, a doctor or registered dietitian can tailor a balanced diet to you.
