This interactive worksheet helps students learn about essential nutrients like carbohydrates, fats, and proteins through matching games and pyramid analysis.

Here are the solutions to the homework problems based on the worksheet provided.

1. Match each food to the nutrient it contains

To solve this, we look at what each group of foods is best known for providing to our bodies:
* Oil, Butter, Cheese, Nuts: These foods are rich in energy-dense oils and fats. They match with fats.
* Tomatoes, Cauliflower, Carrots: Fruits and vegetables are packed with essential micronutrients. They match with vitamins and minerals.
* Bread, Cereals, Pasta: These are grain-based foods (starches) that provide fuel. They match with carbohydrates.
* Lean Beef, Chicken, White Fish: Meats and fish are the primary sources for building muscle and repairing tissue. They match with proteins.

2. Choose the correct nutrient to complete the definitions

We need to pick the right word from the list (carbohydrates, fats, proteins, vitamins and minerals) for each sentence:

* "______ help us to stay healthy."
* Vitamins and minerals keep our immune system strong and organs working well.
* Answer: Vitamins and minerals
* "______ help us grow. They make your hair and nails grow. They also repair body tissues."
* Protein is the "building block" nutrient used for growth and repair.
* Answer: Proteins
* "______ build a store of extra energy for when we need it."
* When we eat more energy than we use immediately, our bodies store it as fat.
* Answer: Fats
* "______ give us energy to run, ride a bike and study."
* Carbohydrates are the body's main source of quick energy for activity and brain function.
* Answer: Carbohydrates

3. Complete these sentences about the food pyramid

The food pyramid shows how much of different foods we should eat. The bottom is the largest section (eat most), and the top is the smallest (eat least).

* Top Level (Orange Box): This level contains sweets, cakes, and fatty foods. We should eat these rarely because they have lots of sugar or fat but few nutrients.
* Sentence: "The food on this level is unhealthy (or not essential) because it has lots of fat and sugar. Eat it in special occasions."
* Middle Levels (Yellow Box): This level usually contains dairy, meat, fish, and oils. We need them, but not as much as fruits and veggies.
* Sentence: "The food on this level is essential but in small quantities. Eat a little of it everyday."
* Bottom Levels (Green Box): This large base contains fruits, vegetables, bread, cereals, and pasta. These are the foundation of a good diet.
* Sentence: "The food on these levels are essential for good health. Eat some everyday!"
