NTR 101: Assessing Nutrition and Genetics Flashcards
(13 cards)
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
