    Study Notes

    Basic Nutrition

    • Definition of Nutrition: The science of how the body uses food for energy, maintenance, and growth.
    • Nutrients: Chemical substances derived from food, essential for health maintenance. Examples include fats, carbohydrates, proteins, vitamins, and minerals.
    • Energy-Yielding Nutrients: Provide energy; these include carbohydrates, fats, and proteins. Vitamins and minerals do not yield energy.
    • Kilocalorie (kcal): A common measure of nutritional consumption or requirement, equivalent to the amount of heat required to raise 1 kg of water to 1°C.
    • Nutrient Density: The amount of micronutrients (vitamins and minerals) compared to macronutrients (carbohydrates, lipids, and proteins).
    • Food: Products derived from plants and animals containing essential nutrients absorbed by the body to produce energy.
    • Essential Nutrients: Those nutrients that the body cannot synthesize and must be obtained from the diet.
    • RDA/RENI: Represents the best estimate of the amount of a nutrient adequate for individual needs.
    • Factors Affecting RDA: Age, body size, sex, workload, and physiological conditions. It's set above the mean (nearly 97-98% healthy individuals), to provide a safety margin.
    • Adequate Intake (AI): Approximate level of average nutrient intake, determined through observations and experiments on populations exhibiting normal health.
    • Tolerable Upper Intake Level (UL): The maximum level of nutrient intake that should not be exceeded to avoid adverse health risks.
    • Recommended Energy and Nutrient Intake (RENI): Updated term emphasizing nutrient standards. It encompasses broader nutritional requirements in comparison to RDA.
    • Protein has an RNI, set at 1.17g/kg/day (71 g for men; 62 g for women).

    Energy Requirements

    • Basal Metabolic Rate (BMR): The amount of energy expended at rest. It's calculated by formulas, often involving weight, height, and sex.
    • Total Caloric Requirement (TCR): Total energy expended to sustain life and function. Includes Basal Metabolic Rate (BMR), Physical Activity (PA), Specific Dynamic Action (SDA), and sometimes Thermic Effect of Food (TEF).
    • Recommended Energy and Nutrient Intake (RENI): Updated term emphasizing nutrient standards.
    • Activity Factor: Values for physical activity levels used in calculating Total Caloric Requirement (TCR).
    • Specific Dynamic Action (SDA): The increase in energy expenditure associated with digestion and absorption of foods, a component of the TCR.
    • Resting Energy Expenditure (REE): Measurement close to BMR, done shortly after waking up, under more relaxed conditions.
    • Total Energy Expenditure (TEE): Often considered similar to TCR.

    Macronutrients

    • Acceptable Macronutrient Distribution Range (AMDR): The ranges for carbohydrates, fats, and proteins that are associated with reduced risk of chronic diseases.
    • Carbohydrates: Major energy source, consisting of simple and complex sugars, starches, and fibers. Glycemic Index describes the average rise in blood glucose after consumption.
    • Fats: Essential for hormone production, cell function, and insulation. Saturated, unsaturated, and trans fats have different effects on health.
    • Proteins: Crucial for building and repairing tissues, and various bodily functions.

    Nutritional Assessment

    • Anthropometry: Measurement of physical characteristics (weight, height, body composition) to assess nutritional status. Gomez & Waterlow classifications are commonly utilized.
    • Biochemical Tests: Nutritional status is assessed through blood tests measuring specific nutrients and metabolites.

    Nutritional Disorders

    • Protein-Energy Malnutrition (PEM): A condition caused by insufficient protein and/or energy intake, with specific presentations as Marasmus and Kwashiorkor. Common symptoms and clinical observations are detailed.
    • Other Disorders: Includes other nutritional disorders, such as obesity, associated with unique dietary requirements and discussion.

    Current Issues in Nutrition

    • Vegetarianism: Dietary approach excluding meat and other animal products, with nutritional considerations and concerns.
    • Megavitamin Therapy: Intake of vitamins above the recommended daily allowance, with corresponding potential benefits and risks.
    • Current Nutritional Surveys: Reports and data on nutritional status in various populations which may identify deficiencies, or specific concerns, including those from a 2022 survey.

    Other Considerations

    • Food Labels: Provide essential information about food composition and nutrient content.
    • Food Guide Pyramids: Offer dietary recommendations using a hierarchical structure based on food groups and quantities.
    • Dietary Considerations: Includes factors such as gestational concerns, specific nutritional therapies, and other relevant nutritional guidelines. Also includes specific dietary recommendations for disorders like Coronary Heart Disease (CHD), or Hypertension.
    • Acceptable Macronutrient Distribution Range (AMDR): This range guides the proportion of carbohydrates, fats, and proteins in a healthy diet, with explicit reference to percent of daily calories each nutrient should provide. Dietary considerations for specific conditions and situations, such as a high-sodium diet to excess, or an increased protein requirement, are included.
