Trends in fiber and whole grain intake in the U.S. NHANES 2001‐2010: what’s changing? (810.5)

The objective of this study was to examine the 10 year trends in sources of dietary fiber and whole grain (WG) among the US population using NHANES 2001‐2010. Weighted intakes of fiber and WG were calculated and food sources categorized according to the USDA FNDDS, 5.0. Mean fiber intake for children 4‐18 y was 13.2±0.1 g/d and for adults 19+ y was 16.1±0.2 g/d. Mean WG intake for children was 0.52±0.01 oz eq/d and for adults 0.71±0.02 oz eq/d. Grain products, fruit and vegetables contributed approximately 80% of total dietary fiber for children and adults. “Mixtures, mainly grain, pasta & bread” and “Fruit, excluding berries” were the top 2 sources of dietary fiber for all ages; intakes of both food groups increased (p<0.01) between 2001‐2010. “White bread, rolls” decreased (p<0.01) as the third source of dietary fiber for both children and adults. Intake of “Cereals, not cooked”, the top source of WG for children, decreased (p=0.0003). There was no change in intakes of the two major sources of WG among adults: “Yeast bread, rolls” and “Cereals, not cooked”. Among the top 15 food sources of dietary fiber only 3 included WG. Snacks made an important contribution (蠅18% of total) to intakes of both fiber and WG for all age groups. These results show that fiber and WG are provided by different foods and different strategies are needed to increase fiber without increasing calories, such as including fiber to foods that are already consumed.
