Adherence to the EAT-Lancet Diet and Risk of Stroke and Stroke Subtypes: A Cohort Study
Research output: Contribution to journal › Journal article › Research › peer-review
Background and Purpose:
We investigated the association between adherence to the EAT-Lancet diet, a sustainable and mostly plant-based diet, and risk of stroke and subtypes of stroke in a Danish population. For comparison, we also investigated the Alternate Healthy Eating Index-2010 (AHEI).
Methods:
We used the Danish Diet, Cancer and Health cohort (n=55 016) including adults aged 50 to 64 years at baseline (1993–1997). A food frequency questionnaire was used to assess dietary intake and group participants according to adherence to the diets. Stroke cases were identified using a national registry and subsequently validated by review of medical records (n=2253). Cox proportional hazards models were used to estimate hazard ratios and 95% CIs for associations with the EAT-Lancet diet or the AHEI and risk of stroke and stroke subtypes.
Results:
Adherence to the EAT-Lancet diet was associated with a lower risk of stroke, although not statistically significant (highest versus lowest adherence: hazard ratio, 0.91 [95% CI, 0.76–1.09]). A lower risk was observed for AHEI (0.75 [95% CI, 0.64–0.87]). For stroke subtypes, we found that adherence to the EAT-Lancet diet was associated with a lower risk of subarachnoid hemorrhage (0.30 [95% CI, 0.12–0.73]), and the AHEI was associated with a lower risk of ischemic stroke (0.76 [95% CI, 0.64–0.90]) and intracerebral hemorrhage (0.58 [95% CI, 0.36–0.93]).
Conclusions:
Adherence to the EAT-Lancet diet in midlife was associated with a lower risk of subarachnoid stroke, and the AHEI was associated with a lower risk of total stroke, mainly ischemic stroke and intracerebral hemorrhage.
