Dietary Reference Intakes (DRIs) | A set of reference values for the intake of energy, nutrients, and food components that can be used for planning and assessing the diets of healthy people in the United States and Canada. |
Estimated Average Requirements (EARs) | Intakes that meet the estimated nutrient needs of 50% of individuals in a gender and life-stage group. |
Recommended Dietary Allowances (RDAs) | Intakes that are sufficient to meet the nutri- ent needs of almost all healthy people in a specific life-stage and gender group. A |
Adequate Intakes (AIs) | Intakes that should be used as a goal when no RDA exists. These values are an approximation of the aver- age nutrient intake that appears to sustain a desired indicator of health. T |
Tolerable Upper Intake Levels (ULs) | Maximum daily intakes that are unlikely to pose a risk of adverse health effects to almost all individuals in the specified life-stage and gender group. |
Estimated Energy Requirements (EERs) | Average energy intakes predicted to maintain body weight in healthy individuals. |
Acceptable Macronutrient Distribution Ranges (AMDRs) | Ranges of intake for energy- yielding nutrients, expressed as a percentage of total energy intake, that are associated with reduced risk of chronic disease while providing adequate intakes of essential nutrients. |
empty calories | Calories from solid fats and/or added sugars, which add calories to the food but few nutrients. |
Daily Value | A nutrient reference value used on food labels to help consumers see how foods fit into their overall diets. |
Reference Daily Intakes (RDIs) | Reference values established for vitamins and minerals that are based on the highest amount of each nutrient recommended for any adult age group by the 1968 RDAs. |
Daily Reference Values (DRVs) | Reference values established for protein and seven nutrients for which no original RDAs were established. The values are based on dietary recommendations for reducing the risk of chronic disease. |
Exchange Lists | A system of grouping foods based on their energy and macronutrient content. |
nutritional status | State of health as it is influenced by the intake and utilization of nutrients. |
nutritional assessment | An evaluation used to determine the nutritional status of individu- als or groups for the purpose of identifying nutritional needs and planning personal health-care or community programs to meet those needs. |
24-hour recall | A method of assessing dietary intake in which a trained interviewer helps an individual remember what he or she ate during the previous day. |
food diary | A method of assess- ing dietary intake that involves an individual keeping a written record of all food and drink con- sumed during a defined period. |
food frequency questionnaire | A method of assessing dietary intake that gathers information about how often certain catego- ries of food are consumed. |
diet history | Information about dietary habits and patterns. |
anthropometric measurements | External measurements of the body, such as height, weight, limb circumference, and skin-fold thickness. |
food disappearance surveys | A survey that estimates the food use of a population by monitoring the amount of food that leaves the marketplace. |
National Health and Nutrition Examination Survey (NHANES) | A survey that collects information about the health and nutritional status of individuals in the population. |
