Nutrition Overview

Nutrition focuses on how the body utilizes nutrients from food for energy, growth, repair, and reproduction.
Essential nutrients include carbohydrates, proteins, fats, vitamins, minerals, water, and fiber.
A balanced diet is crucial for maintaining health.

Proteins

Proteins are crucial for building and repairing body tissues, particularly muscle, and making enzymes and antibodies.
Common sources include meat, dairy, eggs, legumes, and nuts.
A deficiency can lead to conditions like kwashiorkor and marasmus in children.
One egg contains approximately 6-6.5 grams of protein.

Carbohydrates

Carbohydrates encompass sugars, starch, and cellulose, primarily sourced from plants and some animal products.
They provide energy; a deficiency can lead to energy depletion.
Key carbohydrate sources: yams, cassava, potatoes, fruits, and legumes.

Fats and Oils

Fats are found in animal products (cheese, butter, milk) and oils mainly from plants (seeds, fruits).
Functions of fats include energy supply, absorption of fat-soluble vitamins (D and E), and insulation for organs.
Excessive consumption of animal fats is linked to heart and circulatory diseases.

Water

Water accounts for approximately 70% of human body mass and is vital for all chemical reactions.
It aids in nutrient transport, digestion, temperature regulation, and waste excretion.
On average, at least 2 liters of water should be consumed daily to prevent dehydration and associated health issues.
Overhydration can lead to water intoxication.

Fiber

Dietary fiber, derived from plants, is essential for digestive health and preventing constipation.
It retains water, resulting in softer feces and helps reduce the risk of colon cancer by cleansing the colon.

Vitamins and Minerals

Essential in minimal amounts for various bodily functions, vitamins and minerals support energy conversion and tissue maintenance.
A balanced diet is critical to avoid deficiencies that can lead to health problems.
