CQ reports, “The US population overall has adequate levels of vitamins A and D and folate, but some groups could use more vitamin D, iodine and iron, the Centers for Disease Control and Prevention reported Monday.”
However, the study reports that some groups are eating fewer vitamins and minerals than they should.”
For example, “rates of iron deficiency were slightly elevated in Mexican-American toddlers and in younger Mexican-American and non-Hispanic black women.”
WebMD reports that when it came to deficiencies for vitamins, the highest deficiencies were found for vitamin D, which “is important for strong muscles and bones, and it may help protect against certain cancers and type 2 diabetes.”
According to WebMD, “the CDC study found that nearly one-third of African-Americans and 12% of Hispanics have levels of vitamin D that are considered low by scientific standards, compared to 3% of whites.”
According to MedPage Today, the researchers were intrigued by the fact that African-Americans had the highest prevalence of vitamin D deficiency, “because clinical data have shown that African Americans have superior bone health.”
MedPage Today adds that the investigators have called for more research in order to explain this finding.
