Background: Implementation of food taxes may promote sustainable diets in a society. This study estimates the potential short-term impacts of taxes on sugar and sweets (SAS), sugar sweetened beverages (SSB) and hydrogenated oil and animal fats (HOAF) in Iran through a social cost-effectiveness analysis.
Methods: In this study, three tax scenarios were evaluated, including a 25% tax on SASs, a 30% tax on SSBs, and a 30% tax on HOAFs.
Objective: To investigate the frequency of various weight loss strategies among adults in the United States and to explore which weight-loss strategies are associated with several demographic factors.
Methods: The study utilized 2017-2020 data from the National Health and Nutrition Examination Survey. Adult participants (N = 3,130) who had tried to lose weight during the past year were included.
Background: The objective is to determine the prevalence of household food insecurity (HFI) based on sociodemographic factors and their relationship to obesity in youth.
Methods: The study included a sample of 1,962 youth (aged 6-18) from the National Health and Nutrition Examination Survey (NHANES). The US Household Food Security Survey Module is used to measure food security over the past 12 months.
Background: Engaging in physical activity (PA) and reducing sedentary behaviors among youth are linked to improved mental and physical health. This study aimed to examine demographic differences among youth adhering to PA and Screen Time (ST) recommendations.
Methods: The present study utilized data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES).
Introduction: Although limited evidence exists on the beneficial reproductive effects of diet quality indices, the association is still largely unknown. We aimed to investigate the association between Diet Quality Index-International (DQI-I) and antral follicle count (AFC) and serum antimullerian hormone (AMH) as precise and sensitive markers of ovarian reserve and to assess the risk of diminished ovarian reserve (DOR) in women seeking fertility treatments.
Methods: In a case-control study, 370 women (120 women with DOR and 250 women with normal ovarian reserve as controls), matched by age and body mass index (BMI), were recruited.
Background And Aim: Price, as a key driver of food purchasing, has an important role in determining the consumer demand. This study is aimed to estimate the effect of food taxes and subsidies on purchasing patterns of Iranian households (HHs).
Methods: This study was performed in two phases.
Aim: Fermented milk products are suggested as a supplementary therapy to help reduce blood lipid levels. However, the results of clinical studies are conflicting.
Data Synthesis: This study systematically reviewed 39 randomized controlled trials (n = 2237 participants) to investigate the effect of probiotic fermented milk products on blood lipids.
Objectives: Few epidemiological data are available regarding the associations of dietary intakes of polyphenols with non-alcoholic fatty liver disease (NAFLD). We sought to examine the associations of dietary intake of polyphenols with the prevalence of NAFLD.
Methods: We analyzed data from a case-control study of 225 patients with NAFLD cases and 450 controls.
Objective: Several randomized controlled clinical trials (RCTs) have investigated the effect of pomegranate (Punica granatum) supplementation in patients with type 2 diabetes mellitus (T2DM), with conflicting results. Therefore, the present study assessed the effect of pomegranate on metabolic status and oxidative stress in patients with T2DM.
Methods: A comprehensive search was conducted in Pubmed, EMBASE, ISI web of science, Cochrane library and Scopus databases until April 2020, to identify RCTs investigating the effect of pomegranate supplementation on glycemic markers (fasting blood glucose (FBG), homeostasis model assessment-estimated insulin resistance index (HOMA-IR), glycosylated hemoglobin percentage (HbA1c) and insulin levels), anthropometric indices (body mass index (BMI) and body weight (BW)), blood lipids (triglycerides (TG), total cholesterol (TC), high lipoprotein cholesterol (HDL-C) and low lipoprotein cholesterol (LDL-C)), inflammatory markers (high sensitive c-reactive protein (Hs-CRP)) and markers of oxidative stress (total antioxidant capacity (TAC)) in adults with T2DM.
Food insecurity is a major and multidimensional global problem, particularly in rural and vulnerable areas. In this cross-sectional study, we aimed to identify the relationship between social support and food insecurity in 404 Iranian rural households. We selected the sample by cluster random sampling and collected data using three questionnaires [demographic, Multidimensional Perceived Social Support Scale (MSPSS), and United States Department of Agriculture food security questionnaires] and analyzed data using chi-square tests and logistic regression (using SPSS version 19.

Methods: A comprehensive search was conducted in PubMed, Scopus, Cochrane Library, and ISI Web of Science from inception up to January 2020, to identify randomized controlled trials (RCTs) investigating the effect of barberry supplementation on glycemic markers including fasting blood sugar (FBS) concentrations, insulin levels, homeostatic model assessment for insulin resistance (HOMA-IR), and glycosylated hemoglobin (HbA1c) percentage.
Background: Over the last decade, many researchers tried to evaluate the effects of collagen supplements on skin aging and surprisingly revealed that the interventions improved skin aging parameters without any inconsistency.
Aim: This systematic review assesses the literature regarding the effects of collagen supplements on skin health parameters in healthy and patient subjects, focusing on mechanisms of action.
Methods: At the first step of search in the databases, 9057 items were obtained.
Unlabelled: Metabolic syndrome (MetS) is a chronic disease with inflammatory and hypercoagulable states. The current study aimed to compare the effects of flaxseed oil and sunflower oil consumption on the coagulation score and selected oxidative and inflammatory parameters in patients with MetS. In this randomized controlled clinical trial, 60 patients with MetS were allocated into 2 groups.

Background: Chronic obstructive pulmonary disease (COPD) has been introduced as a major public health problem. It has been suggested that disruption in function or some adipokines and serum proteins' signaling could play crucial roles in lung diseases. This study's purpose was to investigate the association between serum levels of S100A1, ZAG, and adiponectin with FEV1 in COPD patients.

Background: COPD is a common irreversible obstructive airway disease. S100A1, ZAG, and adiponectin are important regulators of energy metabolism and body weight. Therefore, the aim of this study was to assess resting metabolic rate (RMR) and its association with serum levels of S100A1, ZAG, and adiponectin in cachectic and noncachectic COPD patients.
