The Role of Nutrition in Health: Introduction of DRI's Flashcards
What’s the difference between health and wellness?
Health is both absences of disease and state of complete mental, physical, and social well-being.
Wellness is the positive aspect of health.
Both health and wellness are multidimensional, hierarchical, dynamic, and interconnected.
Dietary Reference Intakes (DRIs)
For healthy people.
Identify the amount needed to prevent deficiency/reduce disease risk.
Where data are available they take into account life stage and gender (biological sex).
Estimated Average Intake (EAR)
Meets the needs of half the healthy population.
Never see presented.
Recommended Dietary Allowance (RDA)
Meets the needs of 97% of the healthy population.
EAR helps calculate RDA.
Is safe excess…
-overestimate how much people should eat.
-population specific (age and gender specific; pregnant or lactating plays role).
-based on population means (height and weight)
-do not account for clinical requirements
EAR and RDA are Related
The RDA is two standard deviations above the EAR.
Adequate Intake (AI)
Based on limited data, more research is needed
Tolerable Upper Limit (UL)
Highest level that poses no health risks.
Chronic Disease Risk Reduction (CDRR)
Nutrient intakes that are expected to reduce the risk of developing a chronic disease.
To set a CDRR, there must be…
-a sufficient level of evidence showing a casual relationship between a nutrient and chronic disease risk and sufficient information on different levels of intake of the nutrient and associated chronic disease risk.
Estimated Energy Requirements (EER)
Average caloric intake predicted to maintain energy balance in healthy adults.
Defined by age, gender, height, weight, and physical activity level.
Acceptable Macronutrient Distribution Range (AMDR)
Range of macronutrient intakes associated with reduced risk of chronic disease.
CHO = 45-65%
Fat = 20-35%
Protein = 10-35%
