Mini Lesson

Your body is like a car — it needs the right fuel to run well. That fuel is food. But not all foods give your body the same things. Eating a variety of healthy foods every day keeps you strong, full of energy, and able to fight off illness.

The five food groups

  • Fruits — provide vitamins and natural sugars for energy. Eat a variety of colors.
  • Vegetables — packed with vitamins, minerals, and fiber. They help digestion and protect against illness.
  • Grains — bread, rice, pasta, and oats give the body carbohydrates for energy. Whole grains are best.
  • Protein — meat, fish, eggs, beans, and nuts help build and repair muscles and tissues.
  • Dairy — milk, cheese, and yogurt provide calcium for strong bones and teeth.

Healthy vs not-so-healthy choices

  • Healthy: apple, carrot sticks, whole-grain bread, water, eggs, yogurt.
  • Eat less often: candy, chips, soda, cake, fried foods — high in sugar, salt, or unhealthy fats.
  • It is fine to enjoy treats occasionally — the key is balance.

Don't forget water!

  • Water is the healthiest drink. Our bodies are about 60% water.
  • Children should drink around 5–6 glasses of water a day.

💡

Ask yourself: "Does this food come from one of the five groups? Does it give my body what it needs — or is it mostly sugar, salt, or fat?"
