Why the study?
To identify modifiable risk factors for type 2 diabetes mellitus and explore the relationship between dietary sodium intake and blood glucose levels.
Does dietary salt intake restriction affect blood glucose levels in hypertensive or normal people?
Does dietary salt intake restriction affect blood glucose levels in hypertensive or normal people?
Dietary salt restriction may be associated with slightly higher, but not clinically significant, blood glucose levels compared to normal or high salt intake.
Low-salt intake raises blood glucose; challenges broad sodium restriction without glycemic monitoring.
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: = 0.109 > 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.
