Study Notes
Introduction to Nutrition
- Nutrition is a biochemical and physiological process using food to support life, including consumption, digestion, absorption, metabolism, and excretion.
Key Influences on Nutrition
- Cultural Influences: Traditions, values, and beliefs influence food choices, preparation, and consumption.
- Economic Factors: Socioeconomic status impacts access to healthy foods and essential nutrients.
- Pleasure and Emotion: Psychological and emotional factors drive food choices (pleasure, comfort, social bonds).
- Nutritional Requirements: Balanced food types, quantities, and combinations are crucial for body needs.
- Social and Family Dynamics: Social networks, family roles, and peer influence affect eating habits and preferences.
- Cultural/Religious Practices: Religious and ethical restrictions guide acceptable food choices in communities.
- Food Preferences: Taste preferences influence food choices.
- Psychosocial Factors: Emotions, stress levels, and mental health conditions affect eating.
- Chronic Disease Management: Diet management is key to preventing and managing chronic diseases.
- Developmental Needs: Nutritional requirements change throughout a lifespan (infancy to old age).
Roles of Nurses in Nutrition Care
- Nutritional Screening: Identifying patients at risk during hospital admission or routine care.
- Healthcare Provider Liaison: Acting as a bridge between dietitians, physicians, and other healthcare professionals.
- Nutrition Resource: Providing nutritional guidance when dietitians are unavailable.
- Nutrition Counseling Reinforcement: Supporting and reinforcing dietary advice from dietitians.
- Discharge Instructions: Providing dietary recommendations for continued care at home.
- Home Care Nutrition Support: Assisting with nutritional care for homebound patients in collaboration with dietitians.
- Monitoring and Documentation: Tracking nutritional progress and reporting concerns.
Important Nutritional Definitions
- Food: Nutritious substances consumed for life maintenance and growth.
- Nutrient: Compounds in food needed for energy, chemical reactions, and bodily health.
- Macronutrients: Nutrients needed in large amounts (grams) providing energy and structure (carbohydrates, proteins, fats).
- Micronutrients: Nutrients needed in smaller amounts (milligrams or micrograms), like vitamins and minerals, for biochemical processes.
- Vitamin: Organic compounds crucial for metabolic processes, immunity, and health (fat-soluble or water-soluble).
- Mineral: Inorganic elements vital for physiological functions (bone formation, nerve transmission, enzyme reactions).
Nutrient Recap: The 7 Essential Nutrients
1. Carbohydrates
- Definition: Organic compounds (C, H, O) in a 1:2:1 ratio, the body's primary energy source.
- Functions: Energy production, storage, protein sparing, reducing ketosis, supporting GI health.
- Sources: Grains, fruits, vegetables, dairy, sugars.
2. Proteins
- Definition: Major structural and functional body components (amino acids).
- Functions: Body structure, enzyme function, hormone/antibody production, fluid balance, acid-base balance, and energy source.
- Sources: Complete (animal products, soy) and incomplete (legumes, nuts) proteins.
3. Lipids (Fats)
- Definition: Organic compounds (insoluble in water), including triglycerides, phospholipids, and sterols.
- Types: Unsaturated (good), saturated and trans (bad) fats.
- Functions: Energy source, insulation/protection, vitamin absorption, cell structure.
- Sources: Animal fats, plant oils, nuts, seeds.
4. Vitamins
- Definition: Organic substances crucial for regulating body functions and metabolic reactions.
- Categories: Fat-soluble (A, D, E, K) and water-soluble (B vitamins, Vitamin C).
- Functions: Coenzymes, antioxidants, therapeutic uses.
5. Minerals
- Definition: Inorganic elements needed for various physiological functions.
- Categories: Major (needed in larger amounts) and trace minerals (needed in smaller amounts).
- Functions: Support bone health, muscle function, nerve transmission, and enzyme activation.
6. Fiber
- Definition: Indigestible plant components supporting digestive health.
- Types: Soluble (slows digestion, reduces cholesterol) and insoluble (increases stool bulk, prevents constipation).
- Sources: Fruits, vegetables, whole grains, legumes, nuts, seeds.
7. Water
- Definition: Essential for life, acting as a solvent and medium for biological processes.
- Functions: Cell structure, temperature regulation, nutrient transport, lubrication.
- Recommended Intake: Different for men (3.7 liters) and women (2.7 liters) per day.
Food Group Theories
- Classifying foods into groups simplifies nutritional planning and promotes balanced diets.
Food Group Classifications
- Staples: Cereals, starchy fruits, roots, and tubers (carbohydrates, vitamins, minerals, fiber)
- Legumes and Nuts: Peas, beans, nuts (protein, carbohydrates, calcium, iron, fiber)
- Vegetables: Dark leafy greens, yellow vegetables (vitamins, minerals, fiber)
- Fruits: Mangoes, guavas, oranges, etc. (carbohydrates, vitamins, minerals, fiber)
- Foods from Animals: Meat, fish, poultry, eggs, dairy, organ meats (protein, iron, B vitamins, fat-soluble vitamins, fat)
- Fats and Oils: Vegetable oils, butter, margarine, coconut oil (fats, vitamin E, A, D)
Multimix Principle
- Combining food groups maximizes nutritional value, particularly in regions with limited dietary variety.
Types of Multimix Combinations
- Double Mix: Combining two food groups (Rice and peas, toast and baked beans, macaroni and cheese)
- Triple Mix: Combining three food groups (Rice, peas, and carrots, ripe plantain, saltfish and callaloo.)
- Quadri-Mix: Combining four food groups (Boiled dumplings, stewed beef, broad beans, and carrots)
Food Composition Tables (FCT)
- Food Composition Tables/Databases provide detailed nutritional information (macronutrients, micronutrients, calories).
- Sources include the Pan-American Health Organization, FAO, European & Asian Food Databases.
Recipe Calculations
- Essential for assessing composite dish nutritional value.
Why Use Recipe Calculations?
- Food composition: Accurate and consistent nutritional assessment for recipes.
- Food consumption surveys: Crucial for nationwide/regional nutrient intake assessment.
- Diet counseling: Allows for personalized dietary plans.
- Food labels: Used by the food industry.
Steps in Recipe Calculations
- Identify ingredients, weights, and preparation methods.
- Apply factors (yield factor, edible coefficient, retention factor).
- Calculate accurate nutritional values using the mixed method.
- Document all data clearly.
Recipe Calculation Methods
- Summing of Raw Ingredients - Underestimates values due to cooking losses
- Ingredient Method - Calculates each ingredient's contribution with factors; no recipe categorization.
- Total Recipe Method - Weights the final cooked product using factors; extensive measurements.
- Mixed Method - Combines yield and retention factors at both ingredient and recipe levels for accuracy (preferred).
Common Errors in Recipe Calculations
- Forgetting cooking aids (water, fat).
- Skipping edible coefficients.
- Incorrect factor application.
- Missing/incorrect nutrient values.
- Introducing zero values where data is unavailable.
Nutrient Recap: Detailed Explanations of Key Nutrients

- Sources: Grains, fruits, vegetables, dairy, sugars.
Proteins
- Definition: Large molecules (amino acids) essential to body structure, reactions, and functions.
- Functions: Structure, enzymes, hormones, immunity, fluid/acid-base balance, transport, energy (when needed).
- Sources: Complete (animal, soy) and incomplete (plant-based) proteins.
Lipids (Fats)
- Definition: Hydrophobic organic compounds. Serve as a concentrated energy source and support essential bodily functions.
- Types: Triglycerides, phospholipids, sterols (cholesterol).
- Functions: Energy storage, insulation/protection, vitamin absorption, cell structure, hormonal regulation.
- Sources: Animal fats, plant oils, nuts, seeds, fish.
Vitamins

Minerals
- Definition: Inorganic elements essential for various physiological functions (bone formation, enzyme activation, nerve transmission).
- Types: Major (Calcium, phosphorus, sodium, potassium) and Trace (Iron, Zinc, copper) minerals.
