Abstract
Background:
Observational studies have shown that insoluble fiber (IF) can be effective
in preventing type 2 diabetes (T2D), but there is a lack of experimental
data on the effect of short-term consumption of IF on metabolic parameters.
We tried to investigate whether there was an improvement in glycemia and
body composition in individuals at risk for T2D after 3 months of IF
consumption.
Methods:
This “Type 2 Diabetes Mellitus Prevention Ukraine (T2DPUA)” study describes
participants with impaired fasting glucose (IFG) as determined by ADA
criteria. The study involved 30 people, including 21 women (70%). Daily,
15 g of IF derived from wheat was used. T2DPUA did not have a placebo group
and the intervention lasted 3 months. Evaluation of fasting plasma glucose
(FPG) and 2h plasma glucose (2hPG), glycated hemoglobin (HbA1c), total
cholesterol, HDL-cholesterol, triacylglycerols, uric acid, and γ-glutamyl
transferase was performed. The baseline and 3-monthly anthropometric
examinations included measurements of weight, waist and hip circumference.
Fat mass was assessed by bioelectrical impedance analysis. Paired samples
t-test or Wilcoxon test were used.
Result:
A decrease of FPG (P = .042), HbA1c
(P < .001), 2hPG (P = .005), weight
(P < .001), body mass index
(P < .001), the proportion of body fat
(P = .006), and the absolute amount of fat
(P < .001), increases in systolic
(P < .001) and diastolic (P = .008)
blood pressure was shown. The number of people with hypertension did not
change. The absolute amount of body fat decreased by almost 5% and tolerance
to the standard glucose load improved by 15%. The dynamics of other
metabolic parameters were not revealed.
Conclusion and Recommendation:
Data about improvement of glycemia and body composition over a short period
of using IF by individuals with IFG are new and deserve larger studies.
