ٍScientists dicovered that Brewer's yeast might have a positive effects on insulin receptors due to its glucose tolerance factor in people with type 2 diabetes. The study was conducted to find out the effects of brewer's yeast supplements on glycemic indices for patients with type 2 diabetes mellitus.
After a randomized double-blind controlled clinical trial, 84 adults (21 men and 63 women) aged 46.3 ± 6.1 years old with type 2 diabetes mellitus were recruited then divided in a random way into two groups: Supplement group receiving brewer's yeast (six 300mg tablets/day, total 1800 mg) and control group receiving placebo (six 300mg tablets/day) for 12 weeks.
Body weight, height, body mass index, food consumption (based on 24h food record), fasting blood sugar (FBS), glycosylated hemoglobin, insulin sensitivity, and insulin resistance were measured before and after the intervention.
The result noticed was The changes in FBS, glycosylated hemoglobin, and insulin sensitivity were significantly different between the two groups during the study .
A considerable difference in FBS was detected, glycosylated hemoglobin, and insulin sensitivity at the end of the study between the two groups .
The changes in body mass index, 24h food record, insulin resistance were not important.
Scientists concluded that dietary supplementation with brewer`s yeast along with patient usual treatment of diabetes can improve blood glucose variables in type 2 diabetes mellitus.
