Why Dairy Is Important for a 10-Year-Old

Dairy foods (like milk, yogurt, and cheese) are important because they give your body special nutrients that help you grow, stay strong, and have energy to play and learn.

1. Important nutrients in dairy

  • Calcium — helps build strong bones and teeth so you grow tall and don’t break bones easily.
  • Protein — helps build and repair muscles, skin and other parts of your body.
  • Vitamin D — works with calcium to make bones strong (your body makes some vitamin D from sunlight too).
  • Potassium, phosphorus, and B vitamins — help your muscles, nerves, and energy.

2. How dairy helps you every day

  1. Builds strong bones and teeth while you are still growing.
  2. Helps muscles grow after running, playing, or doing sports.
  3. Gives steady energy so you can concentrate at school and not feel tired all the time.
  4. Helps your body repair itself after scrapes or bumps.

3. How much dairy do kids your age need?

For most 9–13 year olds, the recommendation is about 3 cups of dairy a day. Examples that count as 1 cup each:

  • 1 cup (about 240 mL) of milk
  • 1 cup of yogurt
  • 1.5 ounces (about 42 grams) of natural cheese (like cheddar)

4. Easy dairy snack and meal ideas

  • Milk with breakfast cereal
  • Yogurt with fruit and a sprinkle of cereal or nuts
  • Cheese stick with apple slices
  • Smoothie: milk or yogurt + banana + berries
  • Grilled cheese sandwich at lunch

5. What if you can't have dairy (lactose intolerance or allergy)?

  • Use fortified plant milks (soy, almond, oat) that say they have added calcium and vitamin D.
  • Eat other calcium-rich foods: tofu, canned salmon with bones, leafy greens (like kale), and fortified cereals.
  • Talk with a parent and a doctor to know the best options for you.

6. Helpful tips

  • Choose low-fat or fat-free milk if your family wants to limit extra fat, unless a doctor says otherwise.
  • Try to limit sugary flavored milks and yogurts — plain yogurt with fruit is a healthier choice.
  • If you don’t like milk, try it warm, in a smoothie, or try different kinds like chocolate milk (occasionally) or yogurt.

Eating dairy (or good alternatives) most days helps your bones, muscles, and energy. If you have questions about allergies or what to eat, ask a parent or your doctor — they can help you pick the best foods for you.
