What Are Macronutrients? Carbs, Protein and Fat Explained

Food is made up of three main macronutrients: carbohydrates, protein and fat. Your body needs all three, and each does a different job.

Carbohydrates

Carbohydrates are the body’s main source of quick energy. They are found in grains, fruit, vegetables, beans and dairy. Choices that include fiber, such as whole grains and beans, tend to keep you full longer than refined options.

Protein

Protein helps build and repair tissue. Good sources include fish, poultry, eggs, dairy, beans, lentils, tofu and nuts.

Fat

Fat provides energy and helps the body absorb certain vitamins. Sources include olive oil, nuts, seeds, avocado and fish, as well as butter and fatty cuts of meat.

Putting it together

There is no single perfect ratio for everyone. A practical approach is to include a source of protein, a source of fiber-rich carbohydrate and some healthy fat in most meals. Individual needs vary with age, activity and health, so a qualified professional can help if you need specific targets.
