Introduction: Dietary fiber has emerged as an important player in dysglycemia
and chronic disease. While it has been reported that African American men
(AAM) have low fiber intake, this dietary aspect has not been well characterized
in AAM veterans.

Methods: Dietary intake (single 24h dietary recall) has been obtained from inner
city AAM veterans. Comparisons and regression analysis have been performed.
Data are reported as Mean±SD or % of recommended dietary allowance (RDA)
/ adequate intake (AI). Fiber intake is compared between lower fiber (LF<25%
RDA) and higher fiber (HF>50% RDA) groups. The comparisons are reported
as % difference of fiber intake in HF vs LF groups [%D= (HF-LF)/LF x 100)].

Results: Participants (N=87): age 58±7 yrs, body weight (Wt) 101±12 kg, BMI
32±3 kg/m2, A1C 6.1±0.3%, Charlson index of chronic disease 2.2±1.1, had
78% hypertension, 53% dyslipidemia, 72% psychiatric problems and consumed
2346±948 cal/d and 10±7 g/d fiber. HF (N=23) vs LF (N=28) had similar age,
body mass index (BMI), waist circumference, % total and android fat, and
HbA1C. LF dietary intakes were lower than RDA/AI for most of macro and
micronutrients, eg 57±21% cal, 45±25% carbs, 80±36% fat, 95±36% protein,
14±6% fiber, 23±23% vitamin (vit) A, 16±16% vit E, 8±8% vit D. HF had mostly
higher intakes than %RDA/AI for 105±37% cal, 95±39% carbs, 133±68% fat,
160±85% protein but lower fiber 78±25% while micronutrients were lower, eg
78±66% vit A, 37±43% vit E, 14±19% vit D. HF vs LF had lower Wt 8% and
height 3% (p<.02 for both). Despite of similar BMI, HF vs LF had increased
intake (%D) of macronutrients: 84% cal, 67% fat, 57% saturated fat, 111% carbs,
69% protein, and 464% fiber (p<.01 for all). Micronutrient intake was increased
(%D) in HF vs LF by 56% to 410% for vit A and E, calcium (Ca), phosphorus
(P), sodium (Na), potassium (K), zinc (Zn), magnesium (Mg), selenium (Se),
molybdenum (Mo), copper (Cu), iron (Fe), and manganese (Mn) (p<.03 for all). In
the regression analysis of the entire group independent predictors of fiber intake
included Wt, cal, fat, vit E, Ca, P, K, Fe, and Mn and these explained 63% of
variability of fiber intake.

Conclusion: Higher fiber intake helps maintain body weight despite of higher
energy intake and is associated with overall healthier diet in AAM veterans with
high disease burden. These results suggest that further efforts to improve the
dietary fiber intake in AAM veterans and likely many other inner city AAM may be
warranted.
