What do Various Nutrients do for our Body?

Key Notes :

Nutrients Overview:

Nutrients are substances found in food that our bodies need to function properly. They help with growth, energy, and maintaining health.

Types of Nutrients:

• Carbohydrates: These are the body’s main source of energy. They provide fuel for daily activities and brain function. Examples: rice, bread, and pasta.

• Proteins: Important for building and repairing body tissues, including muscles. They are essential for growth and development. Examples: meat, eggs, and beans.

• Fats: Provide energy and help absorb certain vitamins. They protect organs and help keep the body warm. Examples: butter, oil, and nuts.

• Vitamins: Help regulate body processes, such as boosting immunity and keeping skin healthy. Each vitamin has a specific role. Examples: Vitamin C (found in citrus fruits) boosts the immune system, while Vitamin D (from sunlight and milk) helps with bone health.

• Minerals: Support various body functions, including bone health, muscle function, and nerve signals. Examples: Calcium (for strong bones) and Iron (for healthy blood).

• Water: Essential for all body functions. It helps with digestion, keeps the body hydrated, and regulates body temperature.

Importance of a Balanced Diet:

Eating a variety of foods ensures we get all the necessary nutrients in the right amounts for good health and energy.

Deficiency and Excess:

• Not getting enough of a nutrient can lead to health problems (e.g., lack of Vitamin C can cause scurvy).
• Consuming too much of certain nutrients, especially fats and sugars, can lead to weight gain and other health issues.

Role of Fiber:

Though not considered a nutrient, fiber aids digestion and prevents constipation. It helps maintain a healthy digestive system.
