Study Notes
Nutrition & Balanced Diet
- Nutrition refers to the process of obtaining and using food for growth, maintenance, and repair of the body.
- A balanced diet contains all the necessary nutrients in the correct proportions to support a healthy body.
Macronutrients & Micronutrients
- Macronutrients are essential nutrients required in large amounts. This includes Carbohydrates, Proteins, and Fats.
- Micronutrients are essential nutrients required in small amounts. This includes Vitamins and Minerals.
- Essential nutrients cannot be produced by the body and must be obtained from food. They include all macronutrients and some micronutrients.
Calories & Energy
- A Calorie is the unit used to measure energy in food.
- Carbohydrates are the primary source of energy for the body.
Carbohydrates
- Fast-releasing carbohydrates provide a quick burst of energy.
- Examples include: White bread, sugar, potatoes
- Slow-releasing carbohydrates provide sustained energy over a longer period.
- Examples include: Wholegrain bread, brown rice, legumes
- Proteins differ from carbohydrates because they contain nitrogen, which is used to build and repair tissues.
Protein
- Animal proteins are complete proteins that contain all essential amino acids.
- Examples include: Meat, poultry, fish, dairy products.
- The growth and development of children and adolescents requires a higher protein intake to support muscle growth and tissue development.
Fats
- Lipids (fats) are made up of fatty acids and glycerol.
- The recommended dietary intake of protein for adults is approximately 0.8 grams per kilogram of body weight.
Diet Composition
- Carbohydrates should make up 45-65% of the total daily calorie intake in a balanced diet.
- Kwashiorkor is a type of malnutrition caused by a deficiency of protein. It leads to a swollen belly, edema, and skin lesions.
