Relationship between maternal caffeine and coffee intake and pregnancy loss: A grading of recommendations assessment, development, and evaluation-assessed, dose-response meta-analysis of observational studies.

Background: Numerous studies report an association between coffee or caffeine consumption and pregnancy loss; however, the nature and strength of this relationship have not been clearly established. Based on recent studies, our meta-analysis aimed to test whether a dose-response relationship between coffee or caffeine consumption and pregnancy loss exists.

Methods: We searched for articles in PubMed, Web of Science, and Scopus published until May 2022.

Effects of an Iranian traditional fermented food consumption on blood glucose, blood pressure, and lipid profile in type 2 diabetes: a randomized controlled clinical trial.

Background: Ash-Kardeh is one of the few fermented foods without a dairy base in Iran, which is traditionally prepared from cereals and plants in the presence of microorganisms (mainly lactic acid bacteria).

Purpose: This study aimed to assess the effects of Ash-Kardeh consumption on blood glucose, lipid profile, and blood pressure in type 2 diabetic patients.

Methods: Forty-six patients with type 2 diabetes were studied in this randomized controlled clinical trial.

Effects of traditional fermented food (Ash-Kardeh) consumption on blood glucose, blood pressure, and lipid profile in type 2 diabetes: a study protocol for a randomized clinical trial.

Background: Many therapeutic methods are recommended for the management of Type 2 diabetes. Ash-Kardeh contains several components such as flavonoids, antioxidants, and dietary fiber which can affect lipid profile and blood pressure in diabetic patients. However, no study has examined the effects of Ash-Kardeh consumption on blood glucose, blood pressure, and lipid profile in type 2 diabetic patients; therefore, the aim of this study will be to examine the effects of Ash-Kardeh consumption on blood glucose, blood pressure, and lipid profile in type 2 diabetic patients.
