Abstract

Objective: To examine the relationship between dietary fiber and the risk of type 2 diabetes in older men and the role of hepatic and inflammatory markers.

Research design and methods: The study was performed prospectively and included 3,428 nondiabetic men (age 60-79 years) followed up for 7 years, during which there were 162 incident cases of type 2 diabetes.

Results: Low total dietary fiber (lowest quartile < or =20 g/day) was associated with increased risk of diabetes after adjustment for total calorie intake and potential confounders (relative risk -1.47 [95% CI 1.03-2.11]). This increased risk was seen separately for both low cereal and low vegetable fiber intake. Dietary fiber was inversely associated with inflammatory markers (C-reactive protein, interleukin-6) and with tissue plasminogen activator and gamma-glutamyl transferase. Adjustment for these markers attenuated the increased risk (1.28 [0.88-1.86]).

Conclusions: Dietary fiber is associated with reduced diabetes risk, which may be partly explained by inflammatory markers and hepatic fat deposition.
