Module 2: Who Needs to Supplement Dietary Nutrients?


This module will discuss the basic National Health and Nutrition Examination Survey (NHANES) data showing the number of individuals who consume below the Estimated Average Requirement ( EAR) and Recommended Dietary Allowance (RDA) of measured essential nutrients as well as how RDAs and Adequate Intakes (AI) are determined. This module will also discuss important nutrients not reported in NHANES and the many factors beyond diet content that affect nutrient status such as nutrigenetics, poor digestion, increase in metabolic need and drug-induced nutrient depletion.

Educational Objectives:

After completing this enduring material, participants should be able to:

  • Define the important distinction between nutrient intake and nutrient status.
  • Define various levels of nutrient intake that are optimal and suboptimal, including functional insufficiencies.
  • Explain how dietary reference intakes and daily values are created and related.
  • Review the number of Americans with suboptimal intake of dietary nutrients.
  • Describe reasons individuals may have functional insufficiencies, independent of their nutrient intake.
  • Examine the role of stomach acid in nutrient absorption.
  • Summarize the role of Drug-induced Nutrient Depletion.
