Highlights
- •This is the first study that investigated whether diets high in fluid fatty acids, either in relative terms (i.e. diets with a low lipophilic index, LI), or in combination with the quantity of fatty acids consumed (lipophilic load, LL), relate to the risk of cardiovascular disease among a European population.
- •In a Dutch population that typically consumes diets high in saturated fatty acids and low in polyunsaturated fatty acids, neither the overall fluidity of the dietary fatty acids consumed (LI), nor the combination of overall fluidity and amount of the dietary fatty acids consumed (LL) related to future risk of CHD or ischemic stroke.
- •Dietary LI and LL calculated in observational studies may have limited added value above original fatty acid classes and food sources in establishing the relation of fatty acid consumption with CVD.
Abstract
Background and aims
The
fluidity of dietary fatty acids consumed has been suggested to
inversely affect coronary heart disease (CHD) risk. Lipophilic index
(LI) represents overall fluidity of the dietary fatty acid profile.
Lipophilic load (LL) represents a combination of overall fluidity and
absolute intake of dietary fatty acids. We investigated the relations of
dietary LI and LL with risk of CHD and ischemic stroke (iStroke).
Methods and results
We
used data from the prospective EPIC-NL study, including 36,520
participants aged 20-70 years. LI and LL were calculated using dietary
intake data estimated with a validated FFQ. Incident CHD (n=2348) and
iStroke (n=479) cases were obtained through linkage to national
registers during 15 years follow-up. LI and LL were not associated with
CHD risk (HRshighest-versus-lowest-quartiles : 0.93 [95%CI:
0.83, 1.04], and 0.92 [95%CI: 0.79, 1.07], respectively), and neither
with iStroke risk (HRs 1.15 (95%CI: 0.89, 1.48), and 0.98 (95%CI: 0.70,
1.38), respectively). Original fatty acid classes (SFA, MUFA and PUFA),
and LI and LL stratified by these fatty acid classes, were overall not
related to CHD and ischemic stroke either.
Conclusions
In
this Dutch population, neither the overall fluidity of the dietary
fatty acid profile (LI), nor the combined fluidity and amount of fatty
acids consumed (LL) were related to CHD or iStroke risk. Dietary LI and
LL may have limited added value above original fatty acid classes and
food sources in establishing the relation of fatty acid consumption with
CVD.
