Study Notes
Introduction to Nutrition: Key Concepts and Terminology
- Nutrition is the biochemical and physiological process of using food for life support, encompassing factors affecting food consumption.
- Nutrition extends beyond food; cultural, economic, psychological, and social factors influence nutritional health.
- Cultural influences affect dietary choices and habits.
- Socioeconomic status impacts food availability and quality.
- Food provides psychological comfort.
- A balanced nutrient intake is crucial.
- Social and family dynamics influence eating habits.
- Dietary restrictions exist based on religious or ethical beliefs.
- Personal preferences based on taste and enjoyment affect choice.
- Emotions, stress, mental health influence eating.
- Diet manages and prevents chronic diseases.
- Nutritional requirements change across life stages.
- Nurses play a critical role in managing patient nutritional health.
- Nutritional screening identifies at-risk patients.
- Nurses act as nutritional guides, particularly when dietitians are unavailable.
- Nurses reinforce counseling and provide dietary guidance post-discharge.
- Nurses monitor and document patient nutritional status.
Important Nutritional Definitions
- Food: Nutritious substance for sustaining life.
- Nutrient: Compounds for energy, reactions, and health.
- Macronutrients: Large amounts (carbohydrates, proteins, fats).
- Micronutrients: Small amounts (vitamins, minerals).
- Vitamin: Organic compound essential for metabolism.
- Mineral: Inorganic element for physiological functions.
The 7 Essential Nutrients
- Carbohydrates: Energy, gut health, and flavor.
- Proteins: Tissue building and repair, enzyme support.
- Fats: Energy storage, insulation, cell function.
- Vitamins: Regulate bodily functions, immune support.
- Minerals: Maintain structure, regulate metabolism.
- Water: Hydration, temperature regulation, waste elimination.
- Fiber: Supports digestive health, cholesterol regulation.
Carbohydrates
- Carbohydrates are organic compounds (C, H, O) in a 1:2:1 ratio (Cx(H₂O)x).
- Carbohydrate functions include energy production, storage, protein sparing, ketosis reduction, biological recognition, and gut health support.
- Carbohydrate sources include grains, fruits, vegetables, dairy, and sugars/sweeteners.
- Whole grains offer more fiber and nutrients.
- Refined grains are processed.
- Enrichment and fortification add lost/missing nutrients.
Proteins
- Proteins are large molecules of amino acids, essential for tissue building and repair.
- Functions include body structure, enzyme function, hormone and secretion production, fluid balance, acid-base balance, and transportation.
- Animal-based proteins are complete (all essential amino acids), while plant-based ones are incomplete.
Fats
- Fats are organic compounds of fatty acids and glycerol.
- Functions include energy storage, cell membrane integrity, hormone synthesis, vitamin absorption, thermal insulation, and organ protection.
- Types of fats include saturated (animal fats), unsaturated (olive oil), monounsaturated, polyunsaturated, and trans fats.
Vitamins and Minerals
- Vitamins are organic compounds needed in small amounts for metabolic and regulatory functions.
- Fat-soluble vitamins (A, D, E, K) are stored.
- Water-soluble vitamins (C and B-complex) require regular intake.
- Minerals are inorganic elements essential for body functions:
- Major minerals (calcium, potassium, magnesium)
- Trace minerals (iron, zinc, iodine).
Dietary Reference Intakes (DRIs)
- DRIs are reference values for planning and assessing nutrient intake of healthy individuals.
- Recommended Dietary Allowance (RDA): 97-98% of healthy individuals.
- Adequate Intake (AI): Used when RDA cannot be determined.
- Tolerable Upper Intake Level (UL): Maximum daily amount likely to cause no adverse effects.
- Estimated Average Requirement (EAR): Nutrient amount to meet the needs of 50% of individuals.
- Acceptable Macronutrient Distribution Range (AMDR): Recommended range of macro intake for chronic disease risk reduction.
- . Daily Value (DV): Nutrient reference values on food labels based on a 2,000-calorie diet.
Biochemical Assessments
- Biochemical assessments involve laboratory tests on blood, urine, and tissues to determine nutritional status.
- Examples include HbA1c (blood glucose over 2-3 months), Renal Function Tests (GFR, BUN, and creatinine), Liver Function Tests (ALT, AST, ALP, Bilirubin), and Lipid Panel (total cholesterol, LDL, HDL, triglycerides).
Nutritional Assessment Methods
- Nutritional assessment evaluates an individual's nutritional status.
- Techniques include anthropometry (height, weight, BMI), biochemical/biophysical assessments, clinical examinations, and dietary assessments.
Dietary History Components
- Dietary history methods include 24-hour recall, food frequency questionnaires (FFQ), analysis of meal patterns, and consideration of food preferences and restrictions/limitations as well as cooking and shopping habits.
Nutrition in Infancy and Childhood
- Infants require more calories per kilogram compared to adults due to rapid growth.
- Exclusive breastfeeding for the first six months and continued breastfeeding with complementary foods for at least 12 months is recommended.
- Breast milk provides adequate protein, fat, minerals, vitamins, and immune factors.
- Infant formulas are available for those who cannot breastfeed.
- Complementary foods are introduced at around 6 months with iron-fortified cereals and purees, gradually adding other foods.
Nutrition for Toddlers and Preschoolers
- Toddler/preschooler daily calorie needs are approximately 1,000 calories, with portion sizes adjusted according to age.
- Dietary guidelines for these age groups emphasize whole grains, fruits, vegetables, lean proteins, and low-fat dairy.
Nutrition Across the Adult Life Stages (Young Adulthood through Seniors)
- Nutritional needs vary across adult life stages due to changes in metabolism, activity levels, and health conditions.
- Specific nutritional needs during various adult life stages, like building and maintaining muscle mass, reducing chronic disease risks, and supporting hormone production, are considered.
Palliative Nutrition
- Palliative nutrition prioritizes patient comfort and quality of life, aiming to manage symptoms like loss of appetite, dysphagia, and dry mouth.
- Approaches include energy-dense foods, protein sources, small frequent meals, and supportive environments with emotional considerations.
- Hydration is crucial with strategies like small sips, ice chips, and mouth swabs.
Diet and Chronic Diseases in the Caribbean
- Obesity is a complex metabolic disease with rising prevalence in Caribbean populations; driven by energy imbalance and obesogenic environments.
- Genetic predisposition contributes to obesity.
- Obesity complications include metabolic disorders, cardiovascular diseases, and musculoskeletal issues.
- Treatment goals include lifestyle changes (dietary adjustment, physical activity, behavioral therapy) to reach initial weight loss targets.
- Eating disorders (anorexia, bulimia, binge eating) are also discussed.
- Malnutrition is common in hospitalized adults due to acute or chronic medical issues.
Digestion, Absorption, Metabolism, and Energy Balance
- Digestion breaks down food for nutrient absorption and use.
- The stages of feeding include ingestion, mechanical and chemical digestion, absorption, assimilation, respiration, and excretion/egestion.
- Digestive processes for carbohydrates, proteins, and lipids are highlighted.
- Food processing, including mechanical/thermal/chemical/and biological methods, influence nutrient retention.
- Effects of cooking methods, such as heat processing and high temperatures, and energy balance factors affect absorption.
