tissues
- Macronutrients: Nutrients which are needed in large amounts
- Micronutrients: Nutrients needed in small amounts
- Organic: Containing carbon
- Inorganic: Not containing carbon
- Amino Acid: Building blocks of protein
- Vitamin: Organic compound needed for reproduction growth and
maintenance of body
- Minerals: Inorganic compounds needed for growth and regulation of
body processes
o Macrominerals: Minerals which are needed in large amounts
o Microminerals (Traceminerals): “ “ “ In small amounts
- Carbohydrate = 4kcal
- Protein = 4kcal
- Fat =9kcal
Nutrition Scientific Process
- Hypotheses: Educated guesses to explain phenomena
- Epidemiology: Science of determining the distribution of diseases in
different populations
- Nutrigenomics: Study of how nutrition affects genetic health
- Correlation: Connections
- Case Control Study: Investigation using a chosen sample
- Clinical Trial: Studies that collect large amount of data to evaluate
effectiveness of a treatment
- Experimental Group: Group exposed to the new factors
- Control Group: Group not exposed to the new factors
- Placebo: A substance with looks but no effect
- Placebo Effect: Psychological reaction due to substance, but in reality
substance has no effect
- Double-Blind Study: Unbaised method of study where neither the
investigators nor subjects know what group the are in
- Peer Review: When peers review and evaluate your experiment
