Recent research published in the Journal of American College of Nutrition found that obese adults have lower micronutrient intakes compared to normal weight adults.

Observational studies have repeatedly found obesity to be a risk factor for vitamin D deficiency. If a person weighs more, their need for vitamin D increases.

According to the CDC, over 67% of Americans are overweight or obese. Researchers recently searched for answers to this health crisis by evaluating the micronutrient intake of adults.

They compared the micronutrient intake status of overweight and obese adults with normal weight adults. Using total nutrient intake from National Health and Nutrition Examination Survey (NHANES) 2001-2008, the researchers determined usual intakes for micronutrients of 18,177 adults.

Over 40% of adults had inadequate vitamin A, vitamin C, vitamin D, vitamin E, calcium, and magnesium. Obese adults had about 5% to 12% lower intakes of micronutrients and significantly higher prevalence of nutrient inadequacy.

The study was supported by Pharmavite, a dietary supplement company based in Northridge, California. Dr. James Brooks, Vice President of Science and Technology of Pharmavite, said, “”To our knowledge this is the first time intakes of micronutrients were assessed by body weight status using a large database, inclusive of more than 18,000 Americans, providing a nationally representative population-based sample of adults.”
