Dietary XXXX intake in a national sample of US adults.

@entity1 @entity1760
Despite the role of @entity1760 in maintaining health, much of the U.S. population has historically not consumed adequate amounts of @entity1760 . Furthermore, significant racial or ethnic disparities in @entity1760 intake exist. Our objective was to provide more recent data about @entity1760 intake in the U.S. population. We analyzed the 24-h dietary recall data from 4257 @entity1 aged >or=20 y from the National Health and Nutrition Examination Survey 1999-2000. The median intake of @entity1760 was 326 mg/d (mean 352 mg/d) among Caucasian @entity1 , 237 mg/d (mean 278 mg/d) among African American @entity1 , 297 mg/d (330 mg/d) among Mexican American @entity1 , 237 mg/d (mean 256 mg/d) among Caucasian @entity1 , 177 mg/d (mean 202 mg/d) among African American @entity1 , and 221 mg/d (mean 242 mg/d) among Mexican American @entity1 . Among @entity1 and @entity1 , Caucasians had significantly higher mean intakes of dietary @entity1760 than African Americans but not Mexican Americans. @entity1760 intake decreased with increasing age (P for linear trend = 0.035 for Caucasians; P for linear trend <0.001 for African Americans and Mexican Americans). @entity1 had higher intakes of @entity1760 than @entity1 for each of the three race or ethnic groups (P < 0.001 in each group). Caucasian @entity1 , African American @entity1 and Caucasian @entity1 who used vitamin, mineral or dietary supplements consumed significantly more @entity1760 in their diets than did those who did not. Substantial numbers of U.S. adults fail to consume adequate @entity1760 in their diets. Furthermore, racial or ethnic differences in @entity1760 persist and may contribute to some health disparities.
