BackgroundThe aim of the present research was to evaluate the relationship between Mediterranean dietary quality index (Med-DQI) and dietary phytochemical index (DPI) with metabolic risk factors of cardiovascular disease in candidates for coronary artery bypass graft (CABG) surgery.MethodsThis was a cross-sectional study on 454 patients aged 35–80 years as candidates of CABG and hospitalized in Tehran Heart Center. Anthropometric and demographic characteristics were obtained from all participants and a 138-item semi-quantitative food frequency questionnaire (FFQ) was used to evaluate Med-DQI and DPI. Biochemical parameters including HbA1C, serum lipids, albumin, creatinine and C-reactive protein (CRP) were assessed by commercial laboratory methods.ResultsPatients with higher scores of “saturated fatty acids” had lower serum albumin concentrations (P < 0.05). High scores of “cholesterol” subgroup was also accompanied with higher serum Hb A1C percent (P = 0.04). Significantly higher concentrations of serum creatinine were also observed in categorizes with lower “fish” scores. Patients with lower phytochemical intakes had significantly higher Med-DQI scores.ConclusionAccording to our findings, high dietary intakes of saturated fatty acids and cholesterol were associated with low serum albumin and Hb A1C concentration. Further studies are needed to better clarify these associations and possible underlying mechanisms.

AbstrakRasio kolesterol total/ HDL merupakan variabel lipoprotein terbaik dalam memprediksi risiko penyakit kardiovaskular. Peningkatan risiko penyakit kardiovaskular dapat disebabkan oleh tingginya kadar kolesterol serum.Minyak sawit mengandung 50% asam lemak jenuh dan 50% asam lemak tidak jenuh. Tujuan penelitian ini adalah mengetahui perbedaan rasio kolesterol total/ HDL antara kelompok kontrol dengan kelompok diet tinggi minyak sawit pada tikus. Penelitian ini adalah eksperimental dengan pendekatan post test only control group design. Sampel penelitian terdiri dari 10 ekor tikus Wistar jantan yang dibagi menjadi kelompok kontrol (K) dan kelompok perlakuan (P). Diet tinggi minyak sawit (minyak sawit 42.5%, 3ml/hari) diberikan pada kelompok P selama empat minggu.Analisis data menggunakan uji t independent. Hasil penelitian menunjukkan terdapat perbedaan peningkatan yang tidak bermakna antara kelompok P dan kelompok K pada rerata kolesterol, yaitu 63.66±9.9(P) 57.39±3.28(K) (p>0.05), rerata HDL 19.44±3.99(P) 17.64±2.00(K) (p>0.05), dan rerata rasio kolesterol total/ HDL 3.26±0.24 (P) 3.31±0.32 (K) (p>0.05). Kesimpulan penelitian ini adalah kadar kolesterol total, HDL, dan rasio kolesterol total/ HDL pada kelompok kontrol dan kelompok diet tinggi minyak sawit tidak berbeda.Kata kunci: diet tinggi minyak sawit, kolesterol, HDL, rasio kolesterol/ HDL AbstractThe ratio of total cholesterol/ HDL is the lipoprotein variables best predict the risk of cardiovascular disease . The increased risk of cardiovascular disease can be caused by high levels of cholesterol exciting. Palm oil contains 50% saturated fatty acids and 50% unsaturated fatty acids. The purpose of this study was to know the differences ratio of total cholesterol/ HDL between the control group and high palm oil diet group in rats. This research was experimental with post-test only control group. The study sample consisted of 10 male Wistar rats were divided into control group (K) and treated group (P). 3ml/day) was given to the group P for four weeks. Analysis of data using independent t test. The results showed there were no significant differences in improvement between groups P and groups K in mean cholesterol, 63.66 ± 9.9 (P) 57.39 ± 3.28 (K) in (p> 0.05), mean HDL 19.44 ± 3.99 (P) 17.64 ± 2.00 (K) in (p> 0.05), and the mean ratio of total cholesterol/ HDL 3.26 ± 0.24 (P) 3.31 ± 0.32 (K) in (p>0.05). The conclusion of this study is total cholesterol, HDL, and the ratio of total cholesterol/ HDL in the control group and the high palm oil diet group did not differ.
