Data from the National Health and Nutrition Examination Survey (NHANES) from 1999-2010 (n = 23,168) reveals that low intakes of dietary fiber are associated with cardiometabolic risk including obesity, metabolic syndrome and inflammation. Average dietary fiber intake per day was 15.7 to 17.0 grams/day, well below recommended levels of 30 g/day. Higher levels of dietary fiber intake were associated with lower levels of inflammation regardless of ethnicity or race.
