    Nutrients and Their Functions

    • Protein: Essential for energy storage and building body tissues.
    • Carbohydrates: Include sugars, starches, and fiber, serving as the primary energy source.
    • Fat: Major energy source, also crucial for storing energy in the body.
    • Vitamins: Organic compounds required in small amounts to support health and growth; crucial for various bodily functions.
    • Minerals: Inorganic elements necessary for numerous physiological processes, including metabolism and bone health.
    • Water: Vital for maintaining hydration, supporting bodily functions, and regulating temperature.

    Health and Dietary Guidelines

    • Nutrition: The study of food and how the body utilizes nutrients to function properly.
    • Daily Value (DV): Recommended nutrient intake that guides dietary choices.
    • Recommended Dietary Allowances (RDA): Standards for daily nutrient intake designed to meet the needs of almost all healthy individuals.
    • Dietary Guidelines for Americans: A framework aimed at improving the dietary habits and overall health of the population.

    Nutritional Concepts

    • Nutrient Density: A measure comparing the nutritional value of foods to their caloric content; higher density indicates more nutrients per calorie.
    • Nutrient Deficiency: Occurs when the body lacks sufficient nutrients, potentially leading to health issues.
    • MyPyramid: A visual tool helping individuals understand food choices and portion sizes for a balanced diet.

    Diet Types and Considerations

    • Vegetarian Diet: Focuses on plant-based foods, often excluding meat and possibly other animal products.

    Specific Nutrient Functions

    • Vitamins:

      • Vitamin A: Maintains skin and eye health; essential for growth and bone health.
      • Vitamin E: Protects cell membranes from oxidative damage.
      • Vitamin K: Important for the blood clotting process.
