How to build a healthy plate: a simple method for every day
Nutrition
Key points
- Half the plate: vegetables and fruit, with more vegetables than fruit.
- A quarter: whole grains such as brown rice, oats, quinoa or whole-wheat bread.
- A quarter: protein, such as beans, fish, poultry, eggs or nuts; red and processed meat less often.
- A meta-analysis linked about 800 g (roughly 10 servings) of fruit and vegetables a day with the lowest risk of death.
The plate method in one sentence
Take an ordinary 9- to 10-inch dinner plate and divide it in your mind: half vegetables and fruit, a quarter whole grains, a quarter protein. Add water instead of a sugary drink and a little healthy fat such as olive oil or nuts.
You do not need to count calories, so it is easy to use every day. The USDA’s MyPlate, the Harvard Healthy Eating Plate and the EAT–Lancet Commission all use a similar model (Willett et al., 2019).
Half the plate: vegetables and fruit
Vegetables and fruit provide fiber, potassium, vitamins and plant compounds with few calories. A meta-analysis of 95 studies found that the more fruit and vegetables people ate, the lower their risk of cardiovascular disease and death from any cause. The lowest risk was seen at about 800 g a day, twice the WHO minimum of 400 g (Aune et al., 2017).
Practical tips:
- Frozen vegetables and berries are as nutritious as fresh and cost less in winter.
- Add vegetables to breakfast: spinach in eggs, tomatoes on whole-grain toast.
- Eat fruit whole rather than drinking it as juice.
A quarter of the plate: whole grains
Whole grains keep the bran and germ of the kernel, and with them fiber and minerals. A series of meta-analyses in The Lancet found that people who ate the most whole grains and fiber had a 15% to 30% lower risk of death, coronary heart disease, stroke, type 2 diabetes and colorectal cancer than those who ate the least (Reynolds et al., 2019).
Good choices: oatmeal, brown rice, barley, quinoa, bulgur, buckwheat, whole-wheat pasta and bread where “whole wheat” is the first ingredient.
A quarter of the plate: protein
The best everyday protein sources are beans, lentils and peas, fish, nuts and seeds, plus poultry and eggs. Eat red meat less often and processed meat (bacon, hot dogs, deli meats) as rarely as possible.
Beans are an underrated food: they combine protein and fiber. In the Mediterranean diet, whose benefits were confirmed in the PREDIMED randomized trial, legumes, fish and nuts play a major role (Estruch et al., 2018).
Sample balanced plates
| Meal | Half | Quarter | Quarter |
|---|---|---|---|
| Lunch | Big green salad, roasted broccoli | Quinoa | Black bean burger |
| Dinner | Roasted vegetables, greens | Brown rice | Baked salmon |
| Breakfast | Berries, a banana | Oatmeal | A handful of walnuts |
Common mistakes
- Vegetables as decoration. A couple of lettuce leaves are not half a plate.
- A huge portion of pasta or bread pushes vegetables off the plate.
- Healthy food, unhealthy toppings: heavy dressings or salty sauces undo the benefits of vegetables.
The plate method is a guide, not a strict rule. Even getting partway there improves the quality of your diet.
Frequently asked questions
How many fruits and vegetables do I need a day?
The Dietary Guidelines for Americans recommend about 2½ cups of vegetables and 2 cups of fruit a day for a 2,000-calorie diet. In a large meta-analysis, the lowest risk of cardiovascular disease and death was seen at about 800 g a day.
Do potatoes count as a vegetable?
On the plate method, potatoes usually go in the starchy quarter with grains rather than in the vegetable half.
How do I apply the plate to soups, chili or stir-fries?
A vegetable-packed chili with beans already combines vegetables and protein. Add a side salad and a slice of whole-grain bread or brown rice and you have a balanced meal.
