Effects of dietary salt intake restriction on blood glucose levels:a meta-analysis of crossover study

ABSTRACT

BACKGROUND/OBJECTIVES@#To identify modifiable risk factors for type 2 diabetes mellitus and explore the relationship between diet sodium intake and blood glucose levels.MATERIALS/METHODS: Based on inclusion and exclusion criteria, we extracted, analyzed, and assessed the available crossover studies of dietary salt intake restriction and insulin resistance in PubMed, Web of Science, MEDLINE, Embase, Wanfang, and CNKI databases. @*RESULTS@#We included 6 studies with 8 sets of data, covering 485 subjects. I2 statistics results showed insignificant heterogeneity among all data (I 2 = 39.2% 0.05) indicated that insignificant publication bias existed. @*CONCLUSION@#This meta-analysis highlights the relationship between dietary sodium intake and blood glucose levels. Our findings show that higher blood glucose levels might be expected in hypertensive or normal people with low-salt consumption compared to those with normal or high-salt consumption, although these differences were not clinically significant.Trial Registration PROSPERO Identifier CRD42021256998
