What are the Components of Food?

Each component in our food plays a vital role in keeping us healthy. Here’s an overview of each nutrient discussed in this chapter:

1. Carbohydrates

Sources: Rice, wheat, maize, potatoes, and sugars.
Function: Carbohydrates are the primary source of energy for the body. They are essential for performing daily activities.
Types of Carbohydrates: Simple (sugar) and complex (starch).

2. Proteins

Sources: Pulses, beans, milk, meat, and eggs.
Function: Proteins help in body growth, repair of tissues, and building muscles. They are often known as the building blocks of the body.
Importance: Essential for children and teenagers for proper growth.

3. Fats

Sources: Butter, oil, nuts, and cheese.
Function: Fats provide more energy than carbohydrates and are stored in the body as a reserve for future energy needs.
Importance: Helps in keeping the body warm and protects organs.

4. Vitamins

Types of Vitamins: Vitamin A, B, C, D, E, and K.
Sources: Fruits, vegetables, fish, and dairy products.
Functions: Each vitamin has specific roles, such as maintaining good vision (Vitamin A), immunity (Vitamin C), and bone health (Vitamin D).

5. Minerals

Important Minerals: Calcium, iron, potassium, and magnesium.
Sources: Green leafy vegetables, dairy products, nuts, and fruits.
Functions: Minerals are essential for strong bones, carrying oxygen in blood (iron), and maintaining heart health.

6. Water

Importance: Water is crucial for digestion, absorption, and transport of nutrients. It helps regulate body temperature and remove waste.

7. Roughage (Dietary Fiber)

Sources: Whole grains, fruits, and vegetables.
Function: Aids in digestion by promoting bowel movement, preventing constipation, and helping in the absorption of nutrients.

Balanced Diet

A balanced diet includes all the necessary nutrients in the right proportion to support a healthy life. This chapter highlights the importance of consuming a mix of foods that provide carbohydrates, proteins, fats, vitamins, and minerals to ensure good health and proper body functioning.

Deficiency Diseases

When our body doesn’t get sufficient amounts of specific nutrients, it may lead to deficiency diseases. For example:

Lack of Vitamin C can lead to scurvy.
Lack of Vitamin D can cause rickets.
Iron deficiency may result in anemia.
