Explanation
Your diet is the food you usually eat: breakfast, lunch, dinner and snacks. Foods are made of nutrients, and each nutrient has a job. Carbohydrates give energy to move and think. They are found in bread, rice, potatoes and pasta. Proteins help the body grow and repair itself. They are found in beans, lentils, eggs, chicken, fish and milk. Fats store energy and help keep us warm. They are found in oil, butter, cheese and nuts, and we need only a little. Most foods have more than one nutrient. A meal with all three helps us. Think about yesterday: write what you ate at each meal. There are no wrong answers. We are just finding out what is in our food.

Youssef writes yesterday’s food. Breakfast: beans and bread. Lunch: rice, chicken and salad. Dinner: eggs and bread. Snack: an orange. He circles the rice and bread (carbohydrates) and the beans, chicken and eggs (proteins).
Which nutrient helps Seif’s muscles grow and repair? Protein. A boiled egg is a good source.
Rice and bread give energy for a football match. They are carbohydrates. Oil and nuts have fats, which we eat in small amounts.
Class activity
My food map. Write what you ate yesterday for breakfast, lunch, dinner and snacks. Use three colours: colour carbohydrate foods yellow, protein foods red and fatty foods blue. Which colour do you see most? Which do you see least? This is not a test: it only shows what is in your food.
