    Study Notes

    Dietary Reference Intakes (DRIs)

    • EAR (Estimated Average Requirement): Represents the daily amount of a nutrient needed to meet the requirements of 50% of healthy individuals in a specific life stage or sex group.
    • RDA (Recommended Dietary Allowance): Provides the recommended daily intake of various nutrients that fulfill the nutritional needs of approximately 98% of healthy individuals.
    • AI (Adequate Intake): Dietary recommendations used when there's insufficient scientific data to establish an RDA.
    • UL (Tolerable Upper Intake Level [Upper Level]): Defines the highest daily average intake of a nutrient that's considered unlikely to cause adverse health effects.

    Establishing RDAs

    • A "margin of safety" is added to the EAR to account for individual variation in nutrient needs.
    • The RDA is high enough to meet or exceed the needs of 97-98% of healthy individuals.

    Applying Nutrient Standards

    • DRIs are used to:
      • Plan nutritious diets for groups of people.
      • Evaluate the nutritional adequacy of a population's diet.
      • Develop specific food products.
      • Provide standards for nutritional labeling (Daily Values).

    Acceptable Macronutrient Distribution Ranges (AMDRs)

    • AMDRs provide nutritionally adequate ranges for macronutrient (fat, carbohydrate, protein) intake, aiming to reduce the risk of diet-related chronic diseases.

    Dietary Guidelines for Jamaica

    • Food guide: A plate depicting the recommended proportions of six food groups for healthy eating. It encourages variety, adequacy, balance, and control.
    • Food groups:
      • Staples (corn, tubers, rice, plantain)
      • Vegetables
      • Fruits
      • Fats and Oils (including avocado and coconut)
      • Animal-source foods (fish, meat, eggs, dairy products)
      • Legumes and nuts.
    • Recommendations:
      • Eat a variety of foods from all food groups daily.
      • Increase intake of fruits and vegetables daily.
      • Include peas, beans, and nuts in daily meals.
      • Reduce intake of salty, processed, and sugary foods and drinks.
      • Engage in physical activity routinely.

    Dietary Guidelines for Barbados

    • The specific details of these guidelines are not mentioned in the provided text.

    Six Food Groups for the Caribbean

    • Staples: Provide carbohydrates, fiber, protein, B complex vitamins, and minerals.
    • Legumes: Supply carbohydrates, fiber, protein, minerals (iron, calcium), B complex vitamins, and vitamin E.
    • Food from Animals: Offer protein, fats, vitamins, and calcium.
    • Fruits: Contain carbohydrates, fiber, water-soluble vitamins, and minerals (potassium).
    • Vegetables: Provide carbohydrates, fiber, B complex vitamins, vitamin C, and minerals (iron, calcium).
    • Fats and Oils: Contribute fats and vitamins A and E.

    Building a Balanced Caribbean Meal

    • Multi-mix principle: Combining different food groups to ensure an adequate intake of essential nutrients.
    • Types of multi-mixes:
      • Two-mix: The simplest and most affordable combination, pairing staples with either legumes or animal protein for a complete protein.
      • Three-mix: Adding non-starchy vegetables to a two-mix.
      • Four-mix: Includes all four foundation food groups (staples, legumes, animal foods, and vegetables) in one meal, often found in one-pot dishes.

    % Daily Value (%DV)

    • The %DV is calculated by dividing the amount of a nutrient in a serving by its daily value and multiplying by 100.

    Assessing Nutritional Health

    • The first step in planning and evaluating nutritional care for individuals or groups.
    • Determined through multiple sources of information.
    • Involves a systematic method of obtaining, verifying, and interpreting nutrition information.

    Individual Assessment

    • Utilizes various methods to collect data and create a complete picture of an individual's nutritional status:
      • Historical Information (Diet & Health):
        • 24-hour recall: A record of all foods and beverages consumed in a 24-hour period.
        • Food Diary or Food Intake Record: Detailed documentation of food intake over a specific period.
        • Food Frequency Questionnaire: Assess the frequency of consumption for various food groups.
        • Diet History: A comprehensive overview of dietary habits.
      • Anthropometric Measurements: Measurements of the body, such as weight, height, body mass index (BMI), and circumferences.
      • Physical Examinations: Assessment of physical characteristics related to nutrition.
      • Laboratory Tests: Blood tests or other laboratory analyses to evaluate nutritional status.

    Anthropometry

    • The study of measuring the human body in terms of bone, muscle, and adipose tissue dimensions.
    • Measurements include:
      • Weight: A measure of body mass.
      • Height/Length: A measure of stature.
      • Circumferences: Measurements of specific body parts (e.g., waist, hip, arm).
      • Bioelectrical Impedance (BIA): A method that measures electrical resistance to assess body composition.

    Common Anthropometry Indices

    • BMI (Body Mass Index): Calculated by dividing weight (kg) by height squared (m²).
    • Waist-To-Hip Ratio (WHR): A measure of fat distribution.
    • Mid-upper Arm Circumference: Indicates muscle and fat mass in the arm.
    • Waist-To-Height Ratio (WHTR): A measure of abdominal fat.

    Diet Assessment Methods

    • 24-Hour Recall: Records everything consumed in a 24-hour period.
    • Food Diary or Food Intake Record: Detailed food intake documentation over a specific time.
    • Food Frequency Questionnaire: Asks the frequency of consumption of certain food groups.
    • Diet History: Comprehensive overview of dietary habits.
