    Study Notes

    Macronutrients

    • Carbohydrates: Primary energy source; includes sugars, starches, and fiber.

      • Types: Simple (sugars) and complex (starches and fibers).
      • Functions: Energy, digestive health, and regulation of blood glucose.
    • Proteins: Essential for growth, repair, and maintenance of body tissues.

      • Made of amino acids; 20 different amino acids, 9 essential.
      • Functions: Enzyme production, immune function, hormone synthesis.
    • Fats: Important for energy storage, hormone production, and cellular functions.

      • Types: Saturated, unsaturated (monounsaturated, polyunsaturated), and trans fats.
      • Functions: Absorption of vitamins (A, D, E, K), insulation, and protection.

    Micronutrients

    • Vitamins: Organic compounds needed in small amounts.

      • Fat-soluble (A, D, E, K) stored in body fat.
      • Water-soluble (B-complex, C) not stored, need regular intake.
    • Minerals: Inorganic elements needed for various bodily functions.

      • Major minerals: Calcium, potassium, magnesium, sodium.
      • Trace minerals: Iron, zinc, selenium, copper.

    Hydration

    • Importance of water: Essential for biochemical reactions, temperature control, and waste removal.
    • Daily intake recommendations vary based on age, gender, and activity level.

    Energy Metabolism

    • Processes: Glycolysis, Krebs cycle, and electron transport chain.
    • ATP (adenosine triphosphate) is the main energy currency of cells.
    • Nutrient utilization: Carbohydrates are primarily metabolized for quick energy, fats for prolonged energy, and proteins as a last resort.

    Nutritional Assessment

    • Methods: Dietary surveys, anthropometric measurements, biochemical tests.
    • Key indicators: Body mass index (BMI), waist-to-hip ratio, and nutrient deficiencies.

    Dietary Guidelines

    • Focus on whole foods: Fruits, vegetables, whole grains, lean proteins, and healthy fats.
    • Limit added sugars, saturated fats, and sodium.
    • Importance of portion control and balanced diet for overall health.

    Special Considerations

    • Nutritional needs vary by age, gender, and health status.
    • Consider factors like pregnancy, lactation, and chronic diseases (e.g., diabetes, heart disease).
    • Emerging trends: Plant-based diets, intermittent fasting, and personalized nutrition.

    Macronutrients

    • Carbohydrates are the primary energy source for the body.
      • They come in simple forms like sugars and complex forms like starches and fibers.
      • Their functions include providing energy, promoting digestive health, and regulating blood glucose levels.
    • Proteins are crucial for growth, repair, and maintaining body tissues.
      • They are composed of amino acids, with 9 being essential for human health.
      • Their roles encompass enzyme production, immune function, and hormone synthesis.
    • Fats are essential for energy storage, hormone production, and cellular functions.
      • Types of fats include saturated, unsaturated (monounsaturated and polyunsaturated), and trans fats.
      • Their functions include absorbing essential vitamins, providing insulation, and offering protection.

    Micronutrients

    • Vitamins are organic compounds needed in small amounts for various bodily functions.
      • They are categorized as fat-soluble (A, D, E, K) or water-soluble (B-complex, C).
      • Fat-soluble vitamins are stored in body fat, while water-soluble vitamins need regular intake as they are not stored.
    • Minerals are inorganic elements that play crucial roles in bodily functions.
      • Major minerals include calcium, potassium, magnesium, and sodium.
      • Trace minerals include iron, zinc, selenium, and copper.

    Hydration

    • Water is essential for biochemical reactions, temperature control, and waste removal.
    • Daily intake recommendations vary based on age, gender, and activity level.

    Energy Metabolism

    • Energy metabolism involves a series of processes: glycolysis, the Krebs cycle, and the electron transport chain.
    • ATP (adenosine triphosphate) is the primary energy currency of cells.
    • Carbohydrates are primarily metabolized for quick energy, fats for prolonged energy, and proteins are used as a last resort.

    Nutritional Assessment

    • Methods for assessing nutrition include dietary surveys, anthropometric measurements, and biochemical tests.
    • Key indicators of nutritional status include body mass index (BMI), waist-to-hip ratio, and nutrient deficiencies.

    Dietary Guidelines

    • Prioritize whole foods: fruits, vegetables, whole grains, lean proteins, and healthy fats.
    • Limit added sugars, saturated fats, and sodium intake.
    • Portion control and a balanced diet are crucial for overall health.

    Special Considerations

    • Nutritional needs differ based on age, gender, and health status.
    • Factors like pregnancy, lactation, and chronic diseases (e.g., diabetes, heart disease) influence nutritional requirements.
    • Emerging trends in nutrition include plant-based diets, intermittent fasting, and personalized nutrition.
