7 Dietary Assessment and Reference Standards Free Online FlashCards

What does dietary assessment estimate?

Dietary assessment estimates food and drink intake and compares it with guidance or reference standards; it does not diagnose nutritional status on its own.

What does the Estimated Average Requirement (EAR) represent?

The EAR is the intake estimated to meet the needs of half of healthy people in a particular group.

Which DRI value is generally used to estimate inadequate intake in a group?

The EAR is generally used to estimate the prevalence of inadequate intakes in a group. The RDA is more commonly used as an individual planning target.

How do food-label Daily Values differ from DRIs?

Daily Values are standardized label references for comparing foods, not individualized nutrient prescriptions or precise requirements for a particular person.

What should you check first on a Nutrition Facts label?

Check serving size and servings per container first. Listed calories and nutrients are usually for one serving, so two servings generally provide twice the listed amounts.

What are the quick low and high guides for % Daily Value?

The FDA describes $5\%$ DV or less as low and $20\%$ DV or more as high. These are quick comparison guides for a nutrient in one serving.

What is a key strength and limitation of a 24-hour dietary recall?

A 24-hour recall collects detailed information about foods and drinks consumed the previous day, but it captures only a snapshot and relies on memory.

What does the Recommended Dietary Allowance (RDA) aim to cover?

The RDA is an intake that meets the estimated requirement of nearly all healthy people in a group, about $97\text{–}98\%$.

When is an Adequate Intake (AI) used?

An AI is a recommended intake used when evidence is insufficient to establish an EAR and RDA. Intake below an AI does not by itself establish deficiency.

What does the Tolerable Upper Intake Level (UL) indicate?

The UL is the highest usual daily intake unlikely to pose a risk of adverse effects for nearly all healthy people. It is not a recommended target.

What does the Estimated Energy Requirement (EER) estimate?

The EER estimates the energy intake needed to maintain energy balance, based on age, sex, body size, and physical activity level.

What does the Acceptable Macronutrient Distribution Range (AMDR) describe?

The AMDR is a range for the proportion of energy supplied by carbohydrate, fat, or protein, intended to support nutrient adequacy and health.
