2-Nutritional Requirements Flashcards
what is dietary reference intake?
an estimation of nutrient intakes for healthy people
Type of DRI is
RDA, AI,EAR, ULs
Mention 3 parameters for DRI!
nutrients intake, life stage group, heights and weights
Mention 3 methods use to determined DRI
animal models (less reliable), human feeding studies, observational studies, randomized clinical trial
To establishing tolerable upper intake, several points need to be take into account. Explain those 4 points!
- hazard identification : determine the effect caused by high intakes of specific nutrients
- dose response assessment:
- intake assesment: evaluate the range and distribution of the intakes of specific food/nutrients
- risk characterization: Estimation of
the fraction of the population & evaluation of the magnitude with which these excess
intakes exceed the UL
Energy recommendation for macronutrients refer to …
Estimated energy requirements (EER) and acceptable macronutrients distribution range (AMDR)
What is the definition of EER?
The average dietary energy intake that is predicted to maintain energy balance in a healthy adult.
Determined based on a defined age, gender, weight, height, and level of physical activity consistent
with good health
Define acceptable macronutrients distribution range (AMDR)!
A ranges of macronutrient intakes that are associated with reduced risk of chronic disease, while providing
recommended intakes of other essential nutrients.
Mention the use of Dietary Reference Intake (DRI)
For the evaluation of dietary data, nutrition education and guides for food selection, food and nutrition assistance program and also other uses
Mention the limitation of DRI!
- Only for healthy people
- May not applied if other deficiencies exist
- Determined based on imperfect data
- Lack of consistency in different countries or commitee
The extended usage of DRI in evaluation of dietary data points, is to evaluate intake data for groups of individuals. Mention several action example regarding evaluating intake data
- Estimating the % of population at risk
- Identify subgroup at risk of inadequate/excessive intake
- Examining changes overtime of the percentage of the population at risk
- Monitoring the potential food supply to meet the nutritional needs of the population
- Examining the trends and changes in food consumption over time
Mention further about the example of uses of DRI intakes based on nutrition education and guides for food selection
- To identify foods that are important contributors of nutrients
- To specify food consumption patterns that might reduce the probability of dietary inadequacy
- To educate individuals and groups about appropriate foods and
food consumption patterns
The uses of DRI in the terms of food and nutrition assistance program can be further elaborate, such as
DRI as:
- The basis for specified meal patterns in the child nutrition program
-As the nutritional goals of a low-cost food plan that
determines benefit levels for the program
- In development of food packages and benefits for various targeted nutrition programs such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)
- In assessment of compliance with nutrition program regulations
