Study Notes
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.
