A higher intake of dietary fiber may decrease the risk of developing cardiovascular disease.
In this study, investigators from Atlanta, Georgia, examined the association between dietary fiber and serum concentration of C-reactive protein (CRP). CRP is a possible predictor of cardiovascular events.
The team used data from the National Health and Nutrition Examination Survey 1999 to 2000.

They found that in the 3920 participants, dietary fiber intake was inversely associated with serum CRP concentration.
They calculated that the odds ratio (OR) for increased CRP concentration was 0.49 for the highest quintile of fiber intake compared with the lowest.
Adjustment for age, gender, race, education, smoking, physical activity, BMI, total energy, and fat intake resulted in a slight attenuation (OR 0.59).
The team found that excluding participants with cardiovascular conditions, diabetes, or cancer did not alter the results.
Dr Umed Ajani and colleagues concluded, "Fiber intake is independently associated with serum CRP concentration and support the recommendation of a diet with a high fiber content".
