New data on the nutrient intakes of Americans reveals that between 34 and 70% have insufficient intakes of magnesium, calcium, and vitamins A, C, D and E. However, if it weren’t for fortified foods and supplements, these percentages would be higher and the list of nutrients lacking in our diets would be much longer say researchers.

The researchers used the National Cancer Institute method to assess intakes of 19 micronutrients in 7,250 American children (aged from 2 to 18) and 8,860 adults. The study also examined the sources of these nutrients to determine the relative impact of natural foods, fortified foods and supplements in meeting our nutritional needs.

Compared with intakes from natural foods alone, enrichment and/or fortification dramatically improved intakes of several key nutrients, including vitamins A, C, and D, thiamin, iron, and folate. With the addition of dietary supplements, intakes of magnesium and vitamins A, C, and E were further increased.

More than 90% of us are getting enough of some nutrients. Among those who obtained their nutrients through natural and fortified foods as well as supplements, less than 10% were below recommended amounts of vitamin B6, folate, zinc, thiamin, riboflavin, niacin, vitamin B12, phosphorus, iron, copper, and selenium.

The bottom line: without enrichment and/or fortification and supplementation, many Americans would not be meeting their recommended micronutrient intake levels. It’s not surprising that the number of doctors recommending their patients take supplements continues to rise.
