Food and Nutrition Basics

Food and Nutrition

• We need energy and material to build and renew body parts (e.g., skin).
• Water and mineral salts are essential inorganic nutrients.
• Water is the medium for metabolic reactions. It transports substances and regulates body temperature.
• Minerals regulate functions and form structures like bones and teeth.
• Fruit, vegetables, and milk provide water and mineral salts.
• Vegetables and fruits also provide many mineral salts and organic nutrients.
• Organic nutrients include carbohydrates, lipids, proteins, and vitamins.
• Carbohydrates (e.g., glucose) provide fast energy for the brain.
• Complex carbohydrates (e.g., starch, cereals, pulses, fruit, and sweet foods) provide most of the body's carbohydrates.
• Lipids (e.g., butter, oils) are energy reserves and protect the body from cold.
• Proteins (e.g., hemoglobin, antibodies) provide cells and structures (e.g., hair, nails). Proteins are found in animal sources (e.g., meat, fish, eggs, milk, cheese) and plant sources (e.g., cereals, pulses).
• Vitamins are essential substances not produced by the body, mainly found in fresh vegetables and fruits.
