Mediterranean dietary quality index and dietary phytochemical index among patients candidate for coronary artery bypass grafting (CABG) surgery

Abstract

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.

Dietary inflammatory index: a potent association with cardiovascular risk factors among patients candidate for coronary artery bypass grafting (CABG) surgery

“…Accordingly, a 125-subject sample size was determined for the study (125 in each group). We also assumed 20% loss (125 + 25) and as men with CAD are twice as women (150 + 300), the final sample size of 450 was considered for the study [ 25 – 27 ]. Reasons for drop-out or exclusion were incomplete dietary questionnaires ( n = 1), and incomplete demographic questionnaires ( n = 5).…”

Science and Healthy Meals in the World: Nutritional Epigenomics and Nutrigenetics of the Mediterranean Diet

“…The MD is characterized by a favorable lipid profile for cardiovascular function, with a high percentage of unsaturated fatty acids from olive oil and nuts [21]. On the other hand, the MD, due to its high content in plant-derived foods, is an extraordinary source of phytochemicals and also ensures a high intake of fibers [22,23]. Key foods of the MD, such as olive oil, oily fish, nuts, yoghurt, several fruits, spices, and herbs, are considered functional foods due to their nutraceutical content [24].…”

Dietary total antioxidant capacity significantly interacts with 6-P21 rs2010963 gene polymorphisms in terms of cardio-metabolic risk factors in patients with metabolic syndrome

“…Previous studies also revealed the association between 6P21 rs2010963 genotype with severity and extent of coronary artery disease [27,28]. In fact, health dietary choices might be inhibitors of 6P21 rs2010963 gene expression [29] while inappropriate dietary habit might induce it [30,31]. The CC genotype and the C allele of 6P21 rs2010963 gene is considered to be the main risk factor of metabolic disorders, cardiovascular events; Nia SA et al showed that C allele of rs2010963 polymorphism was related to increase risk for CAD and to 5-year cardiovascular mortality in Iranian population [32].…”
