Study Notes
Nutrition Concepts
- Metabolism: Refers to the sum of biochemical and physiological processes allowing the body to grow and maintain itself.
- Nutrition: Involves the processes of taking in food, releasing its nutrients, assimilating them, and using them for energy and tissue maintenance.
- Nutrition Science: Encompasses the body of scientific knowledge developed through controlled research regarding all aspects of nutrition.
Homeostasis and Dietetics
- Homeostasis: The state of dynamic equilibrium within the body's internal environment, crucial for maintaining stable conditions.
- Dietetics: The science focused on the nutritional planning and preparation of foods and diets to meet dietary needs.
Nutrients and Dietary Guidelines
- Nutrients: Essential substances in food for energy, growth, normal function, and life maintenance.
- Recommended Dietary Allowance (RDA): The average daily amount of a nutrient deemed adequate for most healthy individuals.
- Upper Intake Levels (UL): The maximum amount of a nutrient considered safe for regular consumption by most healthy individuals.
Functional Foods and Metabolites
- Functional Foods: Foods that contain physiologically active compounds offering health benefits beyond basic nutrition.
- Metabolites: Products of various metabolic reactions, involved in energy production and regulation of bodily functions.
True or False Statements
-
True statements:
- Nutrition encompasses the processes of nutrient release and utilization.
- Nutrition science is based on controlled research related to nutrition.
- Homeostasis refers to the dynamic equilibrium of the body’s internal environment.
- Dietetics focuses on nutritional planning and preparation.
- Nutrients are essential for various bodily functions and life maintenance.
- Metabolism consists of biochemical and physiological processes for growth and maintenance.
- Functional foods provide health benefits beyond nutrient contribution.
- Metabolites are the results of metabolic reactions.
-
False statements:
- Recommended Dietary Allowances (RDA) do not represent the maximum but rather the average nutrient requirement.
- Upper Intake Levels (UL) represent maximum safe consumption, not average daily needs.
