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.
-
Historical Information (Diet & Health):
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.
