Sweeteners Alter Gut Microbiota

I have always recommended the avoidance of artificial sweeteners and have previously posted news items discussing their detrimental effects on brain activity .  Now there is very convincing evidence that these non-calorific artificial sweeteners (NAS) can alter the gut microbiota and ultimately affect glucose tolerance.

Initial studies using mice showed that consumption of NAS had a detrimental effect on intestinal microbiota, adversely affecting metabolic pathways that caused glucose intolerance. Researchers then studied a large sample of human volunteers and found that long-term users of NAS were more likely to have higher fasting blood sugar levels and show signs of impaired glucose processing.


This is very interesting to those of us who know how much the gut can be affected in children with ASD.  The extensive use of artificial sweeteners in many processed foods and drinks,and not always 'diet' versions, appears to be another factor that could compromise gut function and glucose tolerance in some individuals.
