The aim of this study was to investigate the association of red, orange and yellow FV, with the 3-year incidence of insulin resistance in adults. Materials and Methods: In this longitudinal study, 940 men and women, aged>19 years were selected from among participants of the Tehran Lipid and Glucose Study. Dietary intakes of fruits and vegetables (FV) were determined using a valid and reliable food frequency questionnaire. Fasting serum glucose and insulin were measured at baseline and again after a 3-year of follow up. Logistic regression models were used to estimate the occurrence of IR across tertiles of color subgroups of FV with adjustment for potential confo...

Methods A total of 2369 participants (19–70 years, 43.5% men) without CVD at baseline (2006–2008) were included and followed-up for 6.7 years. Fatty acids’ dietary intake was estimated using a 168-item semi-quantitative food frequency questionnaire. The CVD incidence risk across tertiles of dietary fatty acids was predicted via Cox proportional hazards regression models. Results The average age and body mass index of the included population were 38.5 ± 13.3 years and 26.6 ± 4.8 kg/m2 at baseline. Over 6.7 years of follow-up, 79 cases of CVD were detected. The risk of CVD was lower in upper tertile of monounsaturated fatty acids, oleic acid, and docosahexaeno...

Methods: In 2006-2008, we used a validated food frequency questionnaire to assess dietary fiber intake among 2295 health professionals with no previous history of heart disease. Subjects were subsequently followed until 2012 for incidence of CVD events. Multivariate Cox proportional hazard regression models, adjusted for potential confounders were used to estimate the risk of CVD across tertiles of total dietary fiber and different types of fiber. Linear regression models were also used to indicate the association of dietary fiber intakes with changes of cardiovascular risk factors during the follow-up. Results: Mean age of participants (42.8% men) was 38.2 ± 13.4, at baseline. Mean (SD) dietary intake of total fiber was 23.4 (8.9) g/day. After adjustment for cardiovascular risk score and dietary confounders, a significant inverse association was observed between intakes of total, soluble and insoluble dietary fiber and CVD risk, in the highest compared to the lowest tertiles (HR = 0.39, 95% CI = 0.18-0.83, HR = 0.19, 95% CI = 0.09-0.41, and HR = 0.31, 95% CI = 0.14-0.69, respectively). Inverse relations were observed between risk of CVD and dietary fiber from legumes, fruits and vegetables; however, dietary fiber intake from grain and nut sources was not related to risk of CVD. Conclusion: Our findings confirmed that higher intakes of dietary fiber from different sources is associated with CVD events and modify its major risk-related factors.

This article focuses on the economic implications and implications of Mao Zedong and Deng Xiaoping's international objective environment and explores the hypothesis that our conceptions are explored through the perspective of the theoretical, conceptual, and empirical approach to Robert Jervis's international politics. Dong and Deng Xiaoping during their leadership in the People's Republic of China have had a decisive influence on the economic policies of the People's Republic of China, with Mao Zedong's conceptions of Communist economic policies and Deng Xiaoping's perceptions leading to reopening policy and economic reforms. That has had different econ...

It gained international economic significance during the 19th century, when several countries officially adopted the Gold Standard. With the world becoming more intertwined, gold has found new importance for economies and investors alike. It has been a safe haven during a time of economic crisis which has been reflected on its price. This paper examines the development of gold in a changing global, political and economic environment. For investors it has become a safe haven during the crisis, but how reliable is gold? How far can investors predict gold’s worth in times of crisis and what kind of crises drives gold? The interplay of global players, governments, their policies, currency strategies and large private investors have complicated the predictability of the gold price. Hence, the present study is...
