Foods rich in fiber may play an important role in regulating body weight. An observational study examined the relationship between fiber from different sources and body fat in elderly subjects.
Data are estimates of dietary intake (questionnaires) of 434 adults aged 60 to 80 years. Dietary intakes were estimated by 126 questions. After adjusting for covariates, the consumption of whole grains was inversely associated with BMI. The consumption of refined grains had no impact on the distribution of body fat. The fiber intake was inversely associated with BMI, while no significant difference was observed between total fiber intake, or fiber from fruits and vegetables, and body composition.
Conclusion: The intake of fiber, particularly from whole grains are associated with a percentage of body fat lower among older adults. Bread, pasta, rice, cereals ... Given a choice!
