    Carbohydrates Function

    Carbohydrates provide glucose, which is converted to ATP (energy) for the body.

    Protein Function

    Proteins provide amino acids, used by cells to make enzymes crucial for bodily functions.

    Fat Function

    Fats provide fatty acids for cell membrane repair/insulation, energy (when glucose is low), and vitamin absorption.

    Macronutrient Ratios

    Optimal Macronutrient intake in percentage: Carbs (45-65%), Fats (20-35%), Proteins (10-35%), Fiber (20-25%).

    Study Notes

    Macronutrients

    • Carbohydrates: Provide glucose, which converts to ATP (energy). Two types: simple and complex. Sources include DNA. 45-65% of daily caloric intake recommended.
    • Proteins: Provide amino acids for enzyme production. Sources include ribosomes and cytoplasm. 10-35% of daily caloric intake recommended.
    • Fats: Breakdown into fatty acids for cell membrane repair, insulation, and energy production when glucose is low. Help absorb vitamins and minerals. Sources include cell membranes. 20-35% of daily caloric intake recommended. Three types: unsaturated (good), saturated (bad), and trans (worst). Monounsaturated fats have one double bond; polyunsaturated fats have multiple double bonds.

    Micronutrients

    • Vitamins: Two classifications: fat-soluble and water-soluble. Examples include vitamins A, B1, B2, B3, B5, B6, B9, B12, C, D, and K.
    • Minerals: Essential for various bodily functions. Examples include calcium, magnesium, potassium, iron, and zinc.

    Water

    • Distribution: Water comprises a significant portion of various body tissues, such as brain (80%), lungs (86%), blood (90%), and kidneys (83%). Overall body water content is approximately 70%.
    • Functions: Water is crucial for detoxification, temperature regulation, joint lubrication, metabolism, nutrient delivery, and the respiratory process.

    Nutrition Process

    • Digestion: Food is broken down into absorbable nutrients, which enter the bloodstream and diffuse to body cells.

    Cholesterol

    • Types: HDL (good) and LDL (bad) cholesterol are two types of cholesterol.

    Enzymes

    • Types: Enzymes are biological catalysts speeding up bodily reactions. Examples include amylase, protease, lipase, pepsin, and lactase. Enzymes have different structural levels: primary, secondary, tertiary, and quaternary.

    Metabolism

    • Types: Metabolism encompasses all biochemical reactions in the body. Two classifications include anabolism and catabolism.

    Malnutrition

    • Definition: Malnutrition is an imbalanced diet.

    Recommendations for Healthy Body Composition

    • Carbohydrates: 45-65%
    • Fats: 20-35%
    • Proteins: 10-35%
    • Fiber: 20-25%

    Vitamin Deficiencies

    • Vitamin C Deficiency: Scurvy.
    • Vitamin D Deficiency: Rickets.

    Mineral Deficiencies

    • Calcium Deficiency: Rickets
    • Iron Deficiency: Anemia
    • Sodium Deficiency: Low blood sugar
    • High Sodium Intake: High blood sugar

    Food Composition

    • Protein-Rich Foods: Foods crucial during growth periods.
    • Carbohydrate-Rich Foods: Provide energy.
    • Mineral-Rich Foods: Important for body protection.

    Benefits of Vitamins and Minerals

    • Vitamin B1: Healthy nervous system
    • Vitamin B2: Energy release, ion transport.
    • Vitamin B3: Healthy skin and nervous system
    • Calcium: Healthy bones, teeth, blood clotting, muscle.
    • Iron: Produces hemoglobin for oxygen transport.
    • Sodium: Water level regulation.
