Eat fiber, live better!
Menée en France auprès de 107 377 participants de la cohorte NutriNet-Santé (âge moyen : 42,8 ans ; durée médiane de suivi : 5 ans ; 78,7 % de femmes), cette étude analyse l'association entre une consommation de fibres alimentaires et le risque de maladies chroniques comme le cancer, en fonction du type (apport total, solubles ou insolubles) et de la source des fibres (fruits, légumes, légumineuses, pommes de terre ou tubercules)
In this issue of the Journal, Partula and coworkers (1) have published a very interesting article regarding the importance of eating fiber for living longer and better. Briefly, these authors found, in > 100,000 middle-aged participants, that a higher intake of dietary fiber was associated with a significant decrease in the risks of both the incidence and mortality of noncommunicable diseases (NCDs) (1). These results persisted despite adjustment for a large number of potential confounders, suggesting that fiber is probably necessary for the prevention of cancer, cardiovascular disease, and early mortality (1). These strong results are likely of great clinical importance to the field of nutritional epidemiology and perhaps public health more broadly. In a previous umbrella review published by our team (2), we reported that higher dietary fiber intake was associated with a significant reduction in cardiovascular disease, pancreatic cancer, and mortality, similar to the study of Partula and coworkers. However, the studies included in this umbrella review were mainly case-control and not, as the current study is, cohort studies.
