BACKGROUND AND AIMS: High total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) could be major risk factors for cardiovascular disease burden among high risk populations especially in South Asians. This systematic review and meta-analysis aimed to quantify the effects of coconut oil compared with other oils and fats on cardio-metabolic parameters.
METHODS: PubMed, Scopus and Web of Science were systematically searched. The main outcomes included are lipid and glycemic parameters. Subgroup analyses were performed to evaluate individual comparisons of vegetable oils and animal fat with coconut oil. Data were pooled using random-effects meta-analysis.
RESULTS: Coconut oil consumption significantly increased TC by 15.42 mg/dL (95% CI, 8.96-21.88, p < 0.001), LDL-C by 10.14 mg/dL (95% CI, 4.44-15.84, p < 0.001) and high density lipoprorein cholesterol (HDL-C) by 2.61 mg/dL (95% CI, 0.95-4.26, p = 0.002), and significantly decreased glycosylated hemoglobin (HbA1c) by 0.39 mg/dL (95% CI, -0.50 to -0.27, p < 0.001) but, it had no effects on triglycerides (TG), (4.25 mg/dL; 95% CI, -0.49-8.99, p = 0.08) when compared with the control group. Sub-group analysis demonstrated that coconut oil significantly increased TC and LDL-C over corn, palm, soybean and safflower oils and not over olive oil. Compared with butter, coconut oil showed a better pattern in cardio-metabolic markers by significantly increasing HDL-C (4.38 mg/dL, 95% CI, 0.40 to 8.36, p = 0.03) and decreasing LDL-C (-14.90 mg/dL, 95% CI, -23.02 to-6.77, p < 0.001).
CONCLUSIONS: Our results suggest that coconut oil consumption results in significantly higher TC, LDL-C and HDL-C than other oils. Consumption of coconut oil can be one of the risk factors for CVDs in South Asians.
