Part F: Short Notes on Energy-Giving and Body-Building Foods

#### 1. Energy-Giving Foods
Note:
Energy-giving foods provide the body with the necessary calories to perform daily activities and maintain bodily functions. These foods are primarily rich in carbohydrates and fats, which are broken down into glucose and fatty acids to produce energy.

- Examples:
- Carbohydrates: Rice, wheat, oats, potatoes, fruits, and sugars.
- Fats: Oils (e.g., olive oil, coconut oil), nuts, seeds, avocados, and dairy products.

#### 2. Body-Building Foods
Note:
Body-building foods are rich in proteins, which are essential for muscle growth, tissue repair, and overall structural development. These foods also contain other nutrients like amino acids, which are the building blocks of proteins.

- Examples:
- Protein-Rich Foods: Meat (chicken, beef, lamb), fish, eggs, dairy products (milk, cheese, yogurt), legumes (beans, lentils), nuts, and seeds.
