Abstract Background Endothelial dysfunction has been proposed as the underlying cause of diabetic angiopathy that eventually leads to cardiovascular disease, major death in diabetes. We recently demonstrated ameliorating effect regular vitamin D intake on glycemic status patients with type 2 diabetes (T2D). In this study, effects improvement status, lipid profile and endothelial biomarkers T2D subjects were investigated. Methods Subjects randomly allocated one two groups receive either plain...
Both vitamin D deficiency and inflammation have been linked to cardiovascular disease, the major cause of death in diabetes. In this study, effects daily intake D-fortified yoghourt drink (doogh) on systemic inflammatory biomarkers subjects with type 2 diabetes (T2D) were investigated.In 12-week randomized controlled trial, T2D received either plain doogh (PD; containing 170 mg calcium no detectable D/250 mL, n(1) = 50) or D3-fortified (FD; 500 IU/250 n(2) twice a day. Glycemic status, body...
Systemic inflammation is thought to have a central role in diabetic long-term complications.The aim of this study was investigate the effects vitamin D either with or without extra calcium on certain inflammatory biomarkers subjects type 2 diabetes (T2D).This double-blind, randomized, controlled trial conducted over 12 wk 90 T2D aged 30-60 yr from both sexes.Subjects were randomly allocated one three groups receive two 250-ml bottles day plain Persian yogurt drink doogh (PD, containing 150...
Abstract Objective To assess the vitamin D status of 9–12-year-old primary-school children in Tehran during autumn and winter 2007–2008. Design A descriptive cross-sectional study. Setting Primary schools city, Iran. Subjects total 1111 aged 9–12 years (573 boys 538 girls) from sixty primary were enrolled Weight, height, BMI serum levels Ca, P, Mg, 25-hydroxyvitamin (25(OH)D), intact parathyroid hormone (iPTH), osteocalcin bone-specific alkaline phosphatase all participants assessed. Dietary...
Interpopulation as well interindividual variations in response to vitamin D intake commonly observed subjects with type 2 diabetes may be related genetic makeup. One of the candidate genes potentially responsible for this diversity is receptor (VDR). This study aimed investigate interactive effect VDR Fok-I polymorphism and on diverse aspects diabetic host response.Glycemic status, lipid profiles, inflammatory biomarkers, genotypes were determined (n = 140) who participated a randomized...
Increased free radicals production due to hyperglycemia produces oxidative stress in patients with diabetes. Pomegranate juice (PJ) has antioxidant properties. This study was conducted determine the effects of PJ consumption type 2 diabetic patients.This a randomized clinical trial performed on 60, 40–65 years old patients.The were randomly allocated either group or control. Patients consumed 200 ml daily for six weeks. Sex distribution and mean age not different between two groups. After...
Abstract Background Both poor vitamin D status and oxidative stress ( OS ) have been independently associated with late diabetic complications, including cardiovascular disease CVD ). The present study aimed to examine the effect of daily intake alone or in combination calcium as a fortified Persian yogurt drink doogh on over 12 weeks. Methods Ninety patients type 2 diabetes aged 30–50 years from both sexes were randomly allocated one three groups receive two 250‐mL bottles day, which was...
Bread can potentially be a suitable vehicle for fortification with vitamin D.This study was undertaken to evaluate the following: 1) bioavailability of D from fortified Iranian bread and 2) possible effects daily consumption on certain health aspects.This randomized, double-blind, placebo-controlled trial conducted over 8 weeks in 90 healthy subjects aged 20-60 years.Subjects were randomly allocated one three groups: (FP; 50 g 25 μg D3 plus placebo daily; n = 30); supplement (SP; plain 3)...
Dietary Diversity Score (DDS), as a proxy for nutritional adequacy, can be used useful tool to assess diet quality, especially in children, due its low cost and ease of use comprehensive studies. This study aimed develop questionnaire estimate dietary diversity also the validity DDS an indicator status among children aged 24 59 months Iran. In addition Questionnaire (DDQ), which was designed based on Food Agriculture Organization (FAO) protocols, two non-consecutive 24-hour recalls were...
Recent data indicate a role for vitamin D in many health aspects including anthropometric measures and blood lipid profiles. Dermal synthesis may be influenced by latitude. However, the contribution of latitude status its association with Iranian children have not been studied to date.We used from National Food Nutritional Surveillance Program. In total, 667 apparently healthy aged 5-18 years were randomly selected six provinces Iran different latitudes, 29 37°. Weight, height, circulating...
ABSTRACT A survey on the occurrence of aflatoxin M 1 (AFM ) was carried out in summer and winter raw milk samples from 93 traditional industrial dairy farms Hamedan district order to address representative data AFM collected these regions. Of 186 samples, detected 119 (63.97%). The mean concentration contaminated 43.4 ng/L, minimum maximum levels were ≤ 10 410 respectively. Fourteen (11.76%) had concentrations excess specified European Union regulations, i.e., 50 ng/L. contamination ratio...
This study was undertaken to design and set up a rather simple, reliable, less expensive high-performance liquid chromatography (HPLC)-based method assay 25(OH)D as diagnostic tool for vitamin D assessment. Serum proteins were precipitated using ethanol and, after 10 minutes incubation at room temperature, methanol:isopropanol. The extraction performed hexane followed by evaporation under nitrogen flow. sediment then reconstituted in methanol passed through polypropylene filter. To run the...
This study was undertaken to evaluate the possible effects of different daily doses black tea intake on certain oxidative stress, inflammatory and metabolic biomarkers in patients with type 2 diabetes mellitus (T2DM).Forty-six known T2DM were randomly assigned either test (n = 23, 57.0 +/- 7.9 years) or control 55.4 8.3 group. Following a one-week 'run-in' period, group received 150, 300, 450 600 ml extract (BTE) during weeks 1, 2, 3 4, respectively. The 150 BTE day throughout intervention...
<i>Background/Aims:</i> Despite the advantages of fortifying flour with iron, there are still special concerns regarding possible adverse effects extra iron consumed by nonanemic individuals. This study aimed to investigate oxidative stress and status following 8 16 months consumption iron-fortified in men. <i>Methods:</i> In a before-and-after intervention study, 78 apparently healthy 40- 65-year-old men were randomly selected from Semnan, northeast Iran. Data...
