Aims/hypothesis: Low adherence to recommendations for dietary saturated fatty acid (SFA) and fibre intake in patients with type 1 diabetes mellitus may heighten their increased risk of cardiovascular disease (CVD) and mortality. We examined the relationship of SFA and total, soluble and insoluble fibre with incident CVD and all-cause mortality in type 1 diabetic patients.
Methods: A prospective cohort analysis was performed in 2,108 European type 1 diabetic patients aged 15-60 years who were free of CVD at baseline and enrolled in the EURODIAB Prospective Complications Study (51% male). Diet was assessed from a standardised 3 day dietary record. HR were calculated using Cox proportional hazards models.
Results: During a mean follow-up of 7.3 years, 148 incident cases of fatal and non-fatal CVD and 46 all-cause deaths were documented. No statistically significant association was found between SFA and CVD and all-cause mortality. Total dietary fibre, per 5 g/day, was associated with lower all-cause mortality risk (HR 0.72;95% CI 0.55, 0.95). This association was stronger for soluble fibre (per 5 g/day, HR 0.34;95% CI 0.14, 0.80) compared with insoluble fibre (per 5 g/day; HR 0.66;95% CI 0.45, 0.97). Similar results were found for the association with CVD.
Conclusions/interpretation: This study suggests that reported dietary SFA is not significantly associated with CVD and allcause mortality in type 1 diabetic patients. On the contrary, higher dietary fibre consumption, especially soluble fibre, within the range commonly consumed by type 1 diabetic patients, may contribute to the prevention of CVD and allcause mortality in type 1 diabetic patients.
