Whole Grain and Fiber Consumption are associated with Lower Body Weight Measures in US Adults: National Health and Nutrition Examination Survey 1999-2004

O'Neil CE, et al. Nutr Res. 2010;30:815-822

Summary

The results of this study confirmed that overall whole grain intakes in US adults are well below recommendations, with mean servings of only 0.63 and 0.77 among adults 19-50 years and 51+ years, respectively. In both groups of adults, BMI and waist circumference (WC) were inversely associated with whole grain intake (p≤0.04), whereas energy and fiber intakes were positively associated with whole grain intakes (p<0.001). Given that whole grains foods are rich sources of dietary fiber, more studies are needed to separate out the protective effects of whole grains on body weight independent of fiber intake.
