Technical Abstract: The objective of this study was to evaluate the effects of consumption of fiber and whole grain (WG) on body weight measures in US adults. A nationally representative sample of U.S. adults participating the NHANES, 1999-2004, was analyzed for body mass index (BMI) according to quartiles of dietary fiber and WG intake. Participants were divided into four fiber consumption groups: <8.9g/d, 8.9 to <13.63, 13.63 to 19.96, =19.96g/day. Participants were also divided into four WG intake groups: <0.6 (Quartile (Q)1; control), 0.6 to <1.5, 1.5 to <3.0 and =3.0 servings (Q4). Increased consumption of dietary fiber was associated with lower BMI and WC in women and lower WC in men. Increased intake of WG was associated with lower BMI (Q1-28.52 vs. Q4-27.78, p<0.05) and WC Q1-94.0 vs.Q4-92.23 cm, p<0.05) in women only, but this association disappeared after adjusting for cereal fiber. The data suggest that dietary fiber is an active component in WG effects.
