Study Notes
Nutritional Fundamentals
- Nutrition is the science of food and its relationship to health, focusing on how nutrients support growth, development, and maintenance.
- Nutrients are dietary components (proteins, vitamins, minerals) vital for well-being.
- Dietetics is the practical application of nutrition principles, planning meals for healthy and ill individuals.
- Good nutrition maintains a healthy status, enabling good growth and health.
Energy-Yielding Foods
- Protein, carbohydrates, and fats were recognized in the 19th century as energy sources.
- Metabolism and energy requirements of these foods are significant areas of study.
Defining Food and Diet
- Food nourishes the body. It provides energy, building blocks, regulation, protection.
- Diet includes all consumed foods and beverages.
- Foods are classified by origin (animal, vegetable) and chemical composition (proteins, fats, carbs, vitamins, minerals).
Classification of Foods
- Bodybuilding Foods: These include meat, milk, poultry, fish, eggs, and pulses, aiding in tissue development.
- Energy-Giving Foods: These include cereals, sugars, oils, and fats, supplying energy.
- Protective Foods: These include fruits, vegetables, and milk, contributing to overall protection and well-being.
Macronutrients
- Proteins: Complex, nitrogenous compounds containing sulfur, also phosphorus, iron in some cases. Made up of amino acids.
- Fats: High-energy source, crucial for vitamin absorption, flavoring, and satiety. Mostly triglycerides in adipose tissue. These consist of saturated, unsaturated (mono, poly), and trans fats.
- Carbohydrates: Main energy source (4 kcal/gram). Essential for fat oxidation and amino acid synthesis. Composed of simple sugars (glucose, fructose, sucrose) and complex carbohydrates (starch, fiber).
Micronutrients
- Vitamins: Essential organic compounds in small quantities for bodily processes, not energy providers. They're categorized into fat-soluble (A, D, E, K) and water-soluble (vitamin C, B-complex).
- Minerals: Inorganic elements needed in small amounts for various bodily functions (bone and muscle health, hormone/enzyme production). Categorized as major minerals (calcium, phosphorus, sodium, potassium, magnesium) and trace minerals (iron, zinc, copper).
Proteins: Detail
- 20 amino acids form the building blocks of proteins.
- 8 amino acids are essential, derived from dietary protein as the body cannot produce them (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine).
- Protein functions include tissue building, repair, osmotic pressure maintenance, synthesis of vital molecules, enzymes, and hormones, and nutrient/oxygen transport.
- Protein nutrition status is assessed by serum albumin concentration (3.5 g/dL or more is healthy).
Essential Amino Acids
- List of essential amino acids.
Fats: Detail
- Types: saturated (solid at room temp, mainly animal sources), unsaturated (liquid at room temperature, mainly plant sources, including omega-3 fatty acids found in fish and plant oils), and trans fats (partially hydrogenated vegetable oils).
- Health risks of trans fats include heart disease, obesity, and other chronic diseases.
Carbohydrates: Detail
- Categorized as simple sugars (glucose, fructose, and sucrose) and complex carbohydrates (starch and fiber).
- Starch is found in grains, legumes, potatoes, and converted to glycogen for storage.
- Fiber is indigestible and contributes to digestive health (insoluble and soluble fiber).
Vitamins: Detail
- Vitamin A: crucial for vision, tissue function, and growth. Deficiency leads to night blindness and xerophthalmia.
- Vitamin D: aids calcium absorption and bone health; deficiency causes rickets/osteomalacia in children/adults.
- Vitamin B12: critical for DNA synthesis and fatty acid synthesis. Deficiency leads to anemia and neurological issues.
- Vitamin C: essential for collagen formation and antioxidant support. Deficiency leads to scurvy.
Minerals: Detail
- Major minerals (calcium, phosphorus, sodium, potassium, magnesium) are essential for various bodily functions.
- Trace minerals (iron, zinc, copper) play critical roles in energy-related processes, immunity, and other body functions.
Essential Nutrients
- Avoiding trans fats is important for health.
Energy Balance
- Energy balance occurs when caloric intake equals energy expenditure.
Obesity
- Obesity is defined as excessive fat accumulation.
- Causes include genetics, lifestyle, medical conditions, and medications.
- Negative consequences include fatigue, shortness of breath, joint pain, diabetes, and cardiovascular problems.
Nutritional Needs in Children
- Crucial for growth and development.
- Recommendations include breastfeeding (vitamin D supplementation) and age-appropriate nutrition.
Geriatric Nutrition
- Addresses physiological, psychological, and social changes in older adults.
- Special concerns include decreased digestion, absorption, taste/smell, and dry mouth (xerostomia).
- Recommendations include improved calcium, vitamin D, fiber, and hydration intake for bone and digestive health.
Oral Health
- Importance of good oral hygiene, particularly in the elderly, to prevent dental caries and periodontal disease.
Antioxidants
- Antioxidants help neutralize free radicals and protect cells from damage.
- Sources include fruits, vegetables, spices, and dark chocolate.
- Benefits include improved oral health and reduced risk of periodontal disease.
