Objectives:
The associations between dietary fat intake and cognitive function are inconsistent and inconclusive. Therefore, this review article has been conducted.
Is there a relationship between different types of fat intake and cognitive impairment?
Study design:
This review article included 9 prospective cohort studies covering a total of 23,402 participants.
Results and conclusions:
The investigators found compared with the lowest category of consumption, the highest category of saturated fat consumption significantly increased risk of cognitive impairment with 40% [RR = 1.40, 95% CI = 1.02-1.91].
The investigators found compared with the lowest category of consumption, the highest category of saturated fat consumption significantly increased risk of Alzheimer disease with 87% [RR = 1.87, 95% CI = 1.09-3.20].
The investigators found total and unsaturated fat dietary intakes were not statistically associated with cognitive outcomes with significant between-study heterogeneity.
The investigators concluded there is an increased risk between saturated fat consumption and both cognitive impairment and Alzheimer disease. Given the substantial heterogeneity in the sample size and methodology used across studies, the evidence presented here should be interpreted with caution.
