Background: Dietary fiber may play a role in obesity prevention. Until now, the role that fiber from different sources plays in weight change had rarely been studied.
Objective: Our aim was to investigate the association of total dietary fiber, cereal fiber, and fruit and vegetable fiber with changes in weight and waist circumference.
Design: We conducted a prospective cohort study with 89,432 European participants, aged 20?78 y, who were free of cancer, cardiovascular disease, and diabetes at baseline and who were followed for an average of 6.5 y. Dietary information was collected by using validated country-specific food-frequency questionnaires. Multiple linear regression analysis was performed in each center studied, and estimates were combined by using random-effects meta-analyses. Adjustments were made for follow-up duration, other dietary variables, and baseline anthropometric, demographic, and lifestyle factors.
Results: Total fiber was inversely associated with subsequent weight and waist circumference change. For a 10-g/d higher total fiber intake, the pooled estimate was ?39 g/y (95% CI: ?71, ?7 g/y) for weight change and ?0.08 cm/y (95% CI: ?0.11, ?0.05 cm/y) for waist circumference change. A 10-g/d higher fiber intake from cereals was associated with ?77 g/y (95% CI: ?127, ?26 g/y) weight change and ?0.10 cm/y (95% CI: ?0.18, ?0.02 cm/y) waist circumference change. Fruit and vegetable fiber was not associated with weight change but had a similar association with waist circumference change when compared with intake of total dietary fiber and cereal fiber.
Conclusion: Our finding may support a beneficial role of higher intake of dietary fiber, especially cereal fiber, in prevention of body-weight and waist circumference gain.
