According to National Health and Nutrition Examination Survey (NHANES) data from 2005 to 2016, approximately 15% of U.S. adults have zinc intakes below the Estimated Average Requirement. This suggests that while overt, severe zinc deficiency is uncommon in the USA, marginal inadequacy is a much more prevalent concern that affects various at-risk groups.
