Objectives:
Findings on the link between dietary intakes of monounsaturated fatty acids (MUFA) and risk of mortality are conflicting. Therefore, this review article has been conducted.
Does monounsaturated fatty acids dietary intake reduce risk of mortality?
Study design:
This review article included 17 prospective cohort studies with a total of 1022,321 participants aged ≥ 20 years, of which 191,283 all-cause deaths, 55,437 cardiovascular diseases (CVD) deaths and 64,448 cancer deaths.
Results and conclusions:
The investigators found combining 15 effect sizes from 11 studies, monounsaturated fatty acids dietary intake was significantly associated with a reduced risk of 6% for all-cause mortality [RR = 0.94, 95% CI = 0.90 to 0.98, I2 = 55.5%, p = 0.005].
Significantly because RR of 1 was not found in the 95% CI of 0.90 to 0.98. RR of 1 means no risk/association.
The investigators found based on 17 effect sizes from 11 studies, no significant association between monounsaturated fatty acids dietary intake and risk of cardiovascular diseases mortality [RR = 0.95, 95% CI = 0.89 to 1.01, I2 =37.0%, p = 0.06].
No significant means that there is no association with a 95% confidence.
The investigators found when combining 10 effect sizes from 6 studies, monounsaturated fatty acids dietary intake was not significantly associated with cancer mortality [RR = 0.99, 95% CI = 0.96 to 1.03, I2 = 13.3%, p = 0.32].
Not significantly because RR of 1 was found in the 95% CI of 0.96 to 1.03. RR of 1 means no risk/association.
The investigators found an additional 5% of energy (5 En%) from monounsaturated fatty acids was significantly associated with a 3% reduced risk of all-cause mortality [RR = 0.97, 95% CI = 0.96 to 0.98], but not with cardiovascular diseases [RR = 0.98, 95% CI = 0.95 to 1.01] and cancer mortality [RR = 0.99, 95% CI = 0.97 to 1.01].
The investigators concluded that monounsaturated fatty acids dietary intake reduces risk of all-cause mortality.
