Effectiveness of low-fat diet on the levels of insulin-like growth factor-1 and insulin-like growth factor binding proteins: a systematic review and meta-analysis of randomized controlled clinical trials.

Background: Previous researches on the effect of low-fat diet (LF) on insulin-like growth factor-1 (IGF-1), and its binding proteins (IGFBPs) did not reach a consensus result, and there is no study summarizing these findings. Thus, this systematic review and meta-analysis of randomized control trials (RCTs) was performed to pool available evidence and answer the question whether dietary fat can affect IGF-1 and IGFBPs or not.

Methods: PubMed, Scopus, ISI Web of Science, Google, Google scholar, ProQuest, and the Cochrane Library were searched without language restrictions until July 2, 2024 to retrieve related studies.

Comparative effects of different beverages on weight loss in adults: a systematic review and network meta-analysis of randomized trials.

Background: There is a lack of clarity on the comparative effects of different beverages on weight loss in adults.

Objective: This study aimed at quantifying and ranking the effects of different beverages on weight loss.

Methods: We searched PubMed, Scopus, and Web of Science up to January 2023.

Effect of Low-Fat Diet on Depression Score in Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Clinical Trials.

Context: Current evidence on the effect of a low-fat (LF) diet on depression scores has been inconsistent.

Objective: To explore the effect of an LF diet on depression scores of adults by systematic review and meta-analysis of randomized controlled trials (RCTs).

Data Sources: The PubMed, ISI Web of Science, Scopus, and CENTRAL databases were searched from inception to June 7, 2023, to identify trials investigating the effect of an LF diet (fat intake ≤30% of energy intake) on the depression score.

The association of major dietary patterns with odds and severity of anxiety disorders: a case-control study.

Background: In the present study, we explored the association between major dietary patterns, odds, and severity of anxiety disorders, which has not been clarified to date.

Methods: This case-control study was conducted on 85 patients who were group-matched by gender with 170 healthy subjects. Dietary intakes were evaluated applying a 147-item validated food frequency questionnaire (FFQ).

Association between empirical dietary inflammatory index, odds, and severity of anxiety disorders: A case-control study.

Diet may be a modifiable factor in the prevention of psychiatric disorders by modulating inflammation. In this study, we evaluated the association between empirical dietary inflammatory index (EDII) that is designed to evaluate the inflammatory potential of diets and anxiety disorders (AD) in adults. This case-control study was carried out on 85 patients who were group matched by gender with 170 healthy subjects.

Comparative effects of nutraceuticals on body weight in adults with overweight or obesity: A systematic review and network meta-analysis of 111 randomized clinical trials.

There is no research on the comparative effects of nutraceuticals on weight loss in adults with overweight or obesity. This study aimed at quantifying and ranking the effects of different nutraceuticals on weight loss. We searched PubMed, Scopus, and Web of Science to November 2022.

The combined association of dietary inflammatory index and resting metabolic rate on cardiorespiratory fitness in adults.

Background: No study has examined the combined association of dietary inflammatory index (DII) of the diet and resting metabolic rate (RMR) on cardiorespiratory fitness (CRF). Therefore, we investigated the combined association between DII and RMR on CRF.

Methods: This cross-sectional study was conducted on 270 adult subjects.

Adherence to the MIND diet is inversely associated with odds and severity of anxiety disorders: a case-control study.

Background: The association between the Mediterranean-DASH diet Intervention for Neurodegenerative Delay (MIND) diet, odds, and severity of anxiety disorders (AD) is still unclear. We aimed to investigate whether adherence to MIND diet is associated with odds and severity of AD.

Methods: The present case-control study carried out on 85 patients who were group matched by gender with 170 healthy subjects.

Association between dietary caffeine, coffee, and tea consumption and depressive symptoms in adults: A systematic review and dose-response meta-analysis of observational studies.

Background: Recent studies have reported an association between dietary caffeine intake (coffee and tea) and the presence of depressive symptoms. However, the findings are not conclusive.

Purpose: This study aimed to examine the correlation between the consumption of dietary caffeine (coffee and tea) and the presence of depressive symptoms in adults.

Dose-dependent effect of vinegar on blood pressure: A GRADE-assessed systematic review and meta-analysis of randomized controlled trials.

Background: There are controversial findings regarding the effect of vinegar on blood pressure based on the evidence accumulated so far.

Methods: A systematic search was conducted through PubMed, Scopus, and ISI Web of Science up to April 2022. We estimated the change in blood pressure for each 30 ml/d increments in vinegar consumption in each trial and then, calculated the mean difference (MD) and 95 %CI using a fixed-effects model.
