Study Notes
Nutrition Concepts
- Nutrition: The organic process of nourishing or being nourished, essential for maintaining life and health.
- Foods: Substances derived from plants or animals that provide energy and nutrients for life maintenance, growth, and tissue repair.
- Diet: The specific foods and beverages consumed by an individual.
Nutrients and Their Nature
- Functional foods: Foods that offer health benefits beyond basic nutrition.
- Phytochemicals: Non-nutrient chemicals in plant-based foods that positively impact the body.
- Nutrients: Essential substances that provide nourishment necessary for growth and life maintenance.
- Essential nutrients: Substances that must be obtained through diet as the body cannot synthesize them.
Energy and Metabolism
- Energy: The capacity of a system to perform work; critical for bodily functions.
- Calories: Units measuring the energy provided by food and consumed by the body.
- Metabolism: The process through which nutrients are broken down to yield energy and support bodily functions and structures.
- Energy density: The amount of energy released per gram of food, measured in kilocalories.
Vitamins and Minerals
- Vitamins: Organic nutrients required in small amounts for health.
- Minerals: Inorganic elements that may be essential nutrients required in small quantities.
Research Methodology
- Blind experiment: Participants are unaware of their group assignment (experimental vs. control) to eliminate bias.
- Control group: The baseline group not receiving the treatment, used for comparison to gauge treatment effects.
- Double-blind study: Both participants and researchers are unaware of who receives the treatment or placebo, reducing bias.
- Experimental group: The group that receives the treatment, involved in assessing the effect of an independent variable.
- Peer review: A process where experts evaluate research proposals to ensure quality and credibility.
- Placebo: An inert treatment given to assess the psychological effect rather than physiological impact.
- Randomization: A method of assigning subjects to groups randomly to enhance the validity of the results.
- Replication: Testing the reliability of findings by repeating experiments under similar conditions.
Study Design and Variables
- Subjects: Individuals or animals observed in a study to gather data.
- Theory: A hypothesis supported by extensive data and testing.
- Validity: The degree to which research findings are based on accurate facts or evidence.
- Variables: Factors that can change or vary in the course of an experiment, impacting the results.
Nutritional Guidelines
- Dietary Reference Intakes (DRIs): A set of guidelines estimating nutrient needs, including Recommended Dietary Allowance (RDA) and Adequate Intake (AI).
- Deficient: Describes a state of inadequate supply or amount of necessary nutrients.
- Adequate Intake (AI): The estimated average nutrient intake level considered sufficient when scientific data is limited.
