NTR 101: Assessing Nutrition and Genetics Flashcards
What is Optimal nutritional status?
Nutrient intake supports body functions and allows for storage of excess. Necessary for normal metabolic function
What is Under-nutrition?
Nutrient intake DOES NOT meet needs. Excess surplus stores must be used
What is a SIGN of a sub-clinical deficiency?
An observational feature- visual manifestation
ex) pale skin caused by anemia
What is a SYMPTOM of a sub-clinical deficiency?
An internal change in body function-not visible
ex) fatigue caused by anemia
What is Over-nutrition?
Nutrient intake exceeds needs
ex) Obesity
ABCDE’ s of assessing Nutritional health:
Anthropometrics
Height, weight and waist circumference
*Analysis of of body measurements and any changes of fat or muscle composition
ABCDE’ s of assessing Nutritional health:
Biochemical
Analysis of blood, urine or feces
*Measures levels of nutrient levels and enzymatic activity
ABCDE’ s of assessing Nutritional health:
Clinical
The search for evidence of diet-related illness.
*Physical exam by doctor, nurse or nutritionist.
ABCDE’ s of assessing Nutritional health:
Dietary Assessment
Look to see what person eats and food history
ex) 24 hr recall, food frequency
ABCDE’ s of assessing Nutritional health:
Environment
What influences the individuals dietary intake
ex) socioeconomic status, education, nationality, who does cooking/shopping
What are some limits of Nutritional Assessment?
- Many signs/symptoms of nutritional deficiencies are non-specific
- Takes a long time for symptoms/signs to develop to establish link
- Possible big gap between 1st sign and clinical event-ex heart attack
What are some diseases with a genetic link?
- Diabetes *Cancer *Osteoporosis
* Hypertension *Cardiovascular Disease
What is a genetic trigger?
*Gene to gene expression
and
*Gene and environmental interactions
