Real sugar can provide calories quickly, but artificial sugar can cause diabetes.
Scientists are now warning that some artificial sweeteners may alter the body’s microbes in ways that alter blood sugar levels, according to new data published in the journal “Cell” and reported by South West News Service.
The sugar substitutes – including saccharin and aspartame – are found in thousands of dietary products such as carbonated drinks, desserts, ready meals and cakes, and can even be found in chewing gum and toothpaste.
Manufacturers have long denied that the substitutions can have adverse effects on the human body, and experts have previously noted that blood sugar levels are not affected by them.
However, the new data suggested that caution may be required.
“In subjects consuming the non-nutritive sweeteners, we were able to identify very marked changes in the composition and function of gut microbes and the molecules they secrete into the peripheral blood,” senior author and professor Eran Elinav of Germany’s National Cancer Center told us. SWNS.
“This seemed to indicate that gut microbes in the human body are quite responsive to each of these sweeteners,” he added.
“When we looked at consumers of nonnutritive sweeteners as groups, we found that two of the nonnutritive sweeteners – saccharin and sucralose – significantly affected glucose tolerance in healthy adults.
“Interestingly, changes in the microbes were highly correlated with the changes noted in humans’ glycemic responses,” Elinav explained.
The professor’s team identified the same phenomenon in mice in 2014. Curious about what might happen to humans, Elinav and colleagues screened more than 1,300 people and found 120 who strictly avoided artificial sweeteners in their daily lives.
That group was divided into six groups — two control groups and four that had taken well below the daily amount of aspartame, saccharin, stevia or sucralose recommended by the US Food and Drug Administration.
Microbial samples from subjects were then injected into germ-free mice raised in completely sterile conditions without their own gut bacteria.
The results of the experiment ultimately suggested that changes in the microbiome in response to human consumption of non-nutritive sweeteners “can sometimes cause glycemic changes in consumers in a very personal way,” the professor concluded, adding that the effects of the sweeteners may vary. per individual due to the unique composition of a person’s microbiome.
Previous research has shown that artificial sweeteners can have a bad effect on a person’s metabolism and appetite control.
A report published by the American Journal of Preventive Medicine in March also found that vaping can lead to high blood sugar and diabetes.
