Study Notes
Nutrition Overview
- Nutrition is the study of food and its utilization by the body for growth, metabolism, and repair.
- It encompasses the quantity and quality of food, along with the processes involved in nourishment.
- Key function of nutrition is to sustain life and promote optimal health.
Nutritional Functions of Foods
- Energy Provision: Carbohydrates and fats serve as primary energy sources.
- Examples include rice, corn, bread, and cooking oils.
- Tissue Building and Repair: Proteins are essential for growth and repairing worn-out tissues.
- Sources: fish, pork, chicken, beef, cheese, and beans.
- Regulation of Body Processes: Vitamins and minerals are crucial for normal bodily functions and development.
- Examples: ripe papaya, guava, and oranges.
Digestion Process
- Digestion breaks down food into essential nutrients: carbohydrates, proteins, fats, and vitamins.
- Key functions include intake, breakdown, nutrient absorption, and waste elimination.
Digestive System Components
- Mouth: Initiates mechanical digestion through mastication; saliva aids in this process.
- Stomach: Mixes food with gastric secretions to form chyme; major enzyme involved is pepsin, which breaks down proteins.
- Small Intestine: Primary site for digestion and nutrient absorption, particularly in the duodenum and jejunum.
- Secretes enzymes and receives pancreatic/liver secretions for digestion.
Macronutrients and Their Roles
- Carbohydrates: Provide energy, with an RDA of 130 grams/day.
- Excess intake may lead to weight gain.
- Protein: Essential for tissue repair and metabolic functions; RDA varies with activity and life stage (0.8 g/kg for adults, up to 2.0 g/kg for children).
- Fats: Contain the highest amount of energy (9 kcal/g).
Acceptable Macronutrient Distribution Range (AMDR)
- Carbohydrates: 45-65%
- Proteins: 10-35%
- Fats: 20-35%
Carbohydrates Classification
- Monosaccharides: Simple sugars like fructose and glucose provide quick energy.
- Disaccharides: Composed of two monosaccharides (e.g., sucrose, lactose).
- Polysaccharides: Complex carbohydrates such as starch and glycogen serve as long-term energy storage.
Case Study Considerations (e.g., Diabetes Management)
- Creating a balanced menu could assist patients like Lorna to manage caloric intake.
- Goals may include weight loss and stable blood sugar levels.
- Recommended carbohydrate sources should be healthy and high in fiber.
Protein Importance
- Essential for repairing and building tissues, supporting metabolic reactions, and maintaining immune function.
- Protein is the only dietary source of essential amino acids and nitrogen for the body.
Daily Protein Requirement
- Estimated based on body weight: weight in kg multiplied by 0.8 g (normal adults), higher for athletes and during pregnancy/lactation.
