Abstract

CARDOSO, Diuli A. et al. A coconut extra virgin oil-rich diet increases HDL cholesterol and decreases waist circumference and body mass in coronary artery disease patients. Nutr. Hosp. [online]. 2015, vol.32, n.5, pp.2144-2152. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2015.32.5.9642.

Introduction: saturated fat restriction has been recommended for coronary arterial disease, but the role of coconut oil (Cocos nucifera L.) extra virgin, lauric acid source in the management of lipid profile remains unclear. Objective: to evaluate the effect of nutritional treatment associated with the consumption of extra virgin coconut oil in anthropometric parameters and lipid profile. Methods: we conducted a longitudinal study of 116 adults of both sexes presenting CAD. Patients were followed in two stages: the first stage (basal-3 months), intensive nutritional treatment. In the second stage (3-6 months), the subjects were divided into two groups: diet group associated with extra virgin coconut oil consumption (GDOC) and diet group (DG). Held monthly anthropometric measurements: body mass, waist circumference (WC), neck circumference (PP), body mass index (BMI). Gauged to collected blood pressure and blood samples were fasted for 12 hours, for total cholesterol analysis and fractions apoproteins (Apo A-1 and B), glucose, glycated hemoglobin (HbA1C), insulin (I). Comparing the averages at the beginning and end of the study employing the paired Student t-independent. And set the diastolic blood pressure by BMI using ANOVA. Analyses were performed using the SPSS statistical package, being significant p < 0.05. Results: the mean age of the population was 62.4 ± 7.7 years, 63.2% male, 70% elderly, 77.6% infarcted, 52.6% with angina, hypertension and dyslipidemia 100%. In the first stage the nutritional treatment reduced body weight, WC, BMI and PP and insulin concentrations, HbA1C, HOMA-IR and QUICK, without changing the other parameters. In the second stage of the study, it was observed that the GDOC maintained the reduction of body mass, BMI, WC, with a significant difference between groups for DC (-2.1 ± 2,7cm; p < 0.01). In addition, there was an increase in HDL-C concentrations, Apo A, with significant difference in GD, only for HDL-C (3.1 ± 7.4 mg/dL; p = 0.02). Conclusion: it was observed that the nutritional treatment associated with extra virgin coconut oil consumption reduced the CC and increased HDL-C levels in patients with CAD.
