Study Notes
Essential Minerals
- Trace minerals are required in smaller amounts but are crucial for overall health.
Primary Fuel Source
- Carbohydrates serve as the main fuel source for the body, particularly for the brain.
High-Calorie Nutrient
- Fat provides 9 kcal (37 kJ) per gram, making it the most calorie-dense nutrient.
Nutrient Regulation
- Vitamins and minerals fall under the category of nutrients that are organic molecules essential for regulating body processes.
Water-Soluble Vitamins
- Vitamins B and C are water-soluble, requiring frequent replenishment due to their solubility in water.
Inorganic Nutrients
- Minerals are inorganic substances necessary for various bodily functions, including sodium, calcium, and iron.
Vital Inorganic Nutrient
- Water is an essential inorganic nutrient vital for health and survival.
Fat-Soluble Vitamins
- Vitamins A, D, E, and K are classified as fat-soluble vitamins, stored in the body's fatty tissues.
RDA Definition
- RDA stands for Recommended Dietary Allowance, indicating the average daily dietary intake level sufficient for the nutritional needs of most healthy individuals.
EER Definition
- EER stands for Estimated Energy Requirement, representing the daily dietary energy intake needed to maintain energy balance.
Reference Values
- Dietary Reference Intakes (DRIs) refer to the reference values used for planning and assessing nutrient intakes in healthy individuals.
Daily Value Percentage
- DV% indicates the percentage of daily values provided by a serving of food relative to a daily recommended intake.
Energy-Yielding Macronutrients
- Energy-yielding macronutrients, including carbohydrates, fats, and proteins, are characterized by their ability to provide energy for bodily functions.
RDA Coverage Percentage
- RDA values are designed to meet the nutrient requirements of approximately 97-98% of healthy individuals.
Food Label Elements
- Key elements required on food labels include serving size, calories, nutrient composition, and percent daily values.
Control Group Purpose
- The control group in an experiment serves as a baseline to compare the effects of the experimental treatment.
Nutrient Information on Labels
- Food labels provide detailed information about nutrient content, including amounts of fats, carbohydrates, proteins, vitamins, and minerals.
Adequate Diet Definition
- An adequate diet supplies all necessary nutrients, caloric needs, and hydration for optimal health.
Core Nutrients on Labels
- The Nutrition Facts Table typically lists core nutrients such as total fat, saturated fat, trans fat, cholesterol, sodium, carbohydrates, fiber, sugars, protein, vitamins, and minerals.
Nutrient Density Concept
- Nutrient density is a measure of the nutrients a food contains relative to its calorie content, emphasizing healthier choices.
Scientific Method Importance
- Employing the scientific method is crucial for researchers to rigorously test hypotheses and validate findings.
Order of Ingredients on Labels
- Ingredients on food labels are listed in descending order by weight, indicating the predominance of each ingredient in the product.
Date Marking Purpose
- Date marking on food labels serves to inform consumers about the freshness and shelf life of food products.
