Healthy Diet for Adolescents (Ages 12-18)

A Guide for Parents and Caregivers

The teen years are a time to grow and change. The foods that teens eat need to support this process. Here are some ways to help your teen eat healthier.

Key Parts of Healthy Eating

Get Enough Calories

Teens need a lot of calories to support their growth and to fuel their bodies. The amount that your teen needs depends on age, sex, and the calories that he or she burns through activity. Most teen girls need about 2,200 calories each day. Teen boys need 2,500 to 3,000 calories each day.

It is easy to eat too many calories by making poor food choices. This can lead to being overweight or obese. Make sure your teen gets the amount of calories they need by:

  • Giving them healthful foods from all food groups
  • Not giving them foods that are high in sugar or fat, such as candy bars, chips, cakes, cookies, donuts, and sugary drinks
  • Giving your teen just enough food and then letting your teen have more if they are still hungry (serving too much food at one time can lead to overeating)

Key Nutrients

Your teen needs:

  • Carbohydrates (carbs): This is your teen's main source of energy. About half of their calories should come from carbs. Your teen should choose healthy carbs like whole grains, fruits, veggies, and milk.
  • Protein: Your teen needs protein to grow and build muscle. About a quarter of your teen’s calories should come from protein. Good sources are poultry, lean meat, seafood, eggs, nuts, soy, legumes, and low-fat and nonfat dairy products.
  • Fat: Teens need about a quarter of their calories as fat. It helps with growth. Fat also helps the body take in vitamins and keep the skin healthy. Your teen should eat healthy fats, such as those found in vegetable oils, nuts, avocados, olives, and fatty fish.

Vitamins and Minerals

Many teens, mainly girls, do not get enough vitamins and minerals. Ask the doctor if your teen should take vitamins.

Here are some vitamins and minerals that teens often do not get enough of:

Vitamin or Mineral Role Good Sources


Helps to build strong bones and teeth

Milk, cheese, yogurt, tofu, orange juice with calcium, cereal with calcium, and canned salmon


Helps with growth

Orange juice, breakfast cereals with folate, bread, milk, dried beans, and lentils


Needed to carry red blood cells; not getting enough from the foods you eat can lead to iron-deficiency anemia

Meat, chicken, fish, and breakfast cereal with iron


Helps with growth and sexual maturation

Chicken, meat, shellfish, whole grains, and breakfast cereal with zinc

Vitamin A

Needed for eyesight and growth and to help the immune system work

Carrots, breakfast cereal with vitamin A, milk, and cheese

Vitamin D

Needed for the body to use the calcium that your teen eats

Milk with vitamin D, salmon, and egg yolks—the sun lets your body make vitamin D, but be aware of the dangers of getting too much sun

Vitamin E

Helps protect the body from harm

Nuts, seeds, whole grains, spinach, and breakfast cereal with vitamin E


Helps keep the heart in rhythm, builds strong bones, and keeps blood pressure within a normal range

Whole grains, green veggies, and legumes


Foods with fiber may put off heart disease and some kinds of cancer. It can also ease constipation and help your teen feel full after eating. Most teens do not eat enough. Teach your teen to choose whole grains and offer them plenty of fruits and veggies.
