The prevalence of metabolic syndrome (MetS) is increasing. It is closely linked to nonalcoholic fatty liver disease. Garlic consumption as a strategy for the management of MetS has been suggested. We investigated the effect of garlic supplementation on MetS components, insulin resistance, fatty liver index (FLI), and appetite in subjects with MetS. Ninety subjects were assigned to receive 1,600 mg/d garlic powder or placebo for 3 months. The primary outcomes included MetS components. The secondary outcomes included insulin resistance, FLI, and appetite. Garlic supplementation compared with the placebo led to a significant increase in high density lipoprotein-cholesterol (4.5 vs. -1.8, p < .001) and a significant reduction in waist circumference (-1.3 vs. 0.0, p = .001), diastolic blood pressure (-6.7 vs. 0.0, p < .001), systolic blood pressure (-7.7 vs. 0.5, p < .001), triglyceride (-40.0 vs. 0.1, p < .001), γ-glutamyl transferase (-3.2 vs. 0.6, p = .01), FLI (-5.5 vs. 0.1, p < .001), insulin (-2.9 vs. -1.1, p < .001), homeostatic model of assessment for insulin resistance (-0.5 vs. -0.3, p < .001) and appetite (hunger: -11.7 vs. 1.7, p < .001; fullness: 10.0 vs. 0.3, p = .001; desire to eat: -6.7 vs. 2.1, p < .001; and ability to eat: -11.5 vs. -1.0, p < .001). Garlic improves MetS components, insulin resistance, FLI, and appetite.

Association between Dietary Intakes of Tea, Coffee, and Soft Drinks in Patients Undergoing Coronary Angiography with Coronary Artery Stenosis.

Int J Prev Med 2019 9;10:172. Epub 2019 Oct 9.

Isfahan Neuroscience Research Center, Alzahra Research Institute, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: Coronary artery disease (CAD) is one of the major causes of mortality that is related to the nutritional habits and lifestyle. The aim of this study was to examine the association between tea, coffee, and soft drink consumption and coronary artery stenosis in patients undergoing coronary angiography.

Methods: Out of all the patients, 208 cases (101 Female) with 57.81 ± 12.18 (mean ± SD) were assigned to participate in this cross-sectional study. In total, 168-items, semi-quantitative food frequency questionnaire collected for assessments of dietary intakes of black tea, coffee, caffeine, and soft drinks and record demographic and clinical questionnaire.

Results: There were negative association between arteries with stenosis of more than 50% number with dietary intakes of tea ( = 0.011, r = - 0.187), coffee ( = 0.069, r = - 0.098) intakes, and dietary caffeine intake ( = 0.043, r = -0.118). The high consumptions of soft drinks ( = 0.005, r = 0.387) were associated with an enhancement in arteries with stenosis of more than 50% number. In addition, dietary consumption of black tea have a negatively significant association with the history of previous angiography ( = 0.044, r = -0.121), the history of previous Stanton ( = 0.035, r = -0.132), and coronary artery bypass graft surgery nomination ( = 0.008, r = -0.216). Coffee consumption showed a significant negative relationship with engagement for coronary artery bypass graft surgery ( = 0.004, r = -0.598).

Conclusions: Dietary intakes of tea, coffee, and caffeine may have a negative relationship with CAD and cardio vascular diseases. Healthy dietary lifestyle is an important issue for the prevention of chronic diseases.

A narrative review on effects of vitamin D on main risk factors and severity of Non-Alcoholic Fatty Liver Disease.

Diabetes Metab Syndr 2019 May - Jun;13(3):2260-2265. Epub 2019 May 22.

The global prevalence of Non-alcoholic fatty liver disease (NAFLD) is increasing rapidly. Many studies have been conducted on the treatment of NAFLD; nevertheless, there is still no approved drug treatment for this disease. Although the pathogenesis of NAFLD is not fully understood, but inflammation, insulin resistance, oxidative stress, obesity and dyslipidemia are among the main causes. Epidemiological studies have shown that hypovitaminosis D is associated with these factors causing NAFLD. In addition, rate of Vitamin D deficiency has been shown to be directly related to the severity of NAFLD. Accordingly, it is believed that vitamin D may help to treatment of NAFLD by improving the above-mentioned risk factors. The purpose of this review is to survey the recent advances in the field of Vitamin D efficacy on risk factors and the severity of NAFLD based on existing evidence, especially the clinical efficiency of vitamin D supplementation in patients with NAFLD.
