Study Notes
Nutrient Requirements and Standards
- A nutrient requirement is the smallest amount of a nutrient that maintains a defined level of nutritional health, preventing deficiency diseases.
- Requirements vary from person to person based on factors like age, sex, health status, physical activity level, and medication use.
- Nutrient requirements change throughout the lifespan.
Dietary Reference Intakes (DRIs)
- DRIs are daily energy and nutrient intake standards used to make dietary recommendations, reduce disease risk, and achieve optimal health.
- The seven DRI standards are:
- Estimated Average Requirement (EAR)
- Recommended Dietary Allowance (RDA)
- Adequate Intake (AI)
- Tolerable Upper Intake Level (UL)
- Chronic Disease Risk Reduction Intake (CDRR)
- Estimated Energy Requirement (EER)
- Acceptable Macronutrient Distribution Range (AMDR)
Estimated Average Requirement (EAR)
- EAR is the daily amount of a nutrient that meets the needs of 50% of healthy people in a particular life stage/sex group.
- EAR is used to establish RDAs and AIs.
Recommended Dietary Allowance (RDA)
- RDA is the daily amount of a nutrient that meets the needs of nearly all healthy individuals in a particular life stage/sex group.
- RDAs are set by adding a "margin of safety" to the EAR, allowing for individual variations in nutrient needs and maintaining tissue stores.
Adequate Intake (AI)
- AI is used when there is not enough information to establish an RDA for a nutrient.
- AI is based on the average daily intake of a nutrient by a group of healthy people, with no signs of deficiency.
Tolerable Upper Intake Level (UL)
- UL is the highest average daily intake of a nutrient that is unlikely to harm most people.
- Consuming amounts above the UL increases the risk of toxicity.
Estimated Energy Requirement (EER)
- EER is the average daily energy intake that meets the needs of a healthy person maintaining their weight.
- EER takes into account physical activity level, height, weight, and life stage/sex group.
Acceptable Macronutrient Distribution Range (AMDR)
- AMDR is a range of carbohydrate, fat, and protein intakes that provide adequate amounts of vitamins and minerals and may reduce the risk of diet-related chronic diseases.
- Examples of AMDRs include:
- Carbohydrates: 45-65% of total energy intake
- Protein: 10-35% of total energy intake
- Fat: 20-35% of total energy intake
Chronic Disease Risk Reduction Intake (CDRR)
- CDRR is a nutrient intake level that reduces chronic disease risk within a healthy population.
- Examples of CDRRs include limiting sodium intake to less than 2300 mg/day to reduce the risk of high blood pressure and heart disease.
Applying Nutrient Standards
- Registered dietitian nutritionists (RDNs) use DRIs to plan nutritious diets and evaluate the nutritional adequacy of a population's diet.
- RDAs and AIs are used to evaluate an individual's dietary practices.
- Pharmaceutical companies and the FDA use nutrient standards to develop formulas and nutrition labels.
