Micronutrient intake in USA
Recommending and using micronutrient supplements remains controversial primarily because of the inconsistencies in published data. Since vitamins and minerals are indispensable components of metabolic processes, determining nutrient status and needs are required for improving personal and therefore public health
A recent report (https://tinyurl.com/y44d7at6) used NHANES 2009 – 2012 data provides more evidence that significant proportions of U.S. population in the age groups 2y – 8y and 9y – 18y have micronutrient intakes below estimated average requirements (ERA). Vitamins A, D, E, and C, folate, calcium, and magnesium are the most under-consumed micronutrients. Fortification and dietary supplements reduced the percentage of children and teens below the ERA.
While the goal that all dietary needs come from whole foods is desirable and laudable, the changing nutrient content in agricultural products, climate change, political instability, and personal and public economic factors make it difficult for ~2 billion individuals to meet their micronutrient needs through food alone.
