Artificial Sweeteners May Raise Blood Sugar Levels: StudyArtificial sweeteners can potentially make blood sugar levels rise despite containing no calories, researchers found in human and mouse studies.
That's because saccharine and its counterparts appear to alter the bacteria residing in the intestines in ways that can impair some people's ability to process glucose, the researchers report in the Sept. 17 issue of Nature. That means rather than helping the current epidemics of obesity and type 2 diabetes in the United States, artificial sweeteners could potentially be contributing to the problem, according to the study.
The researchers found that mice fed artificial sweeteners developed higher blood sugar levels compared to mice drinking plain water or even water laced with sugar.
They further found that they could bring the mice's blood sugar levels back to normal by treating them with antibiotics. And, they could induce higher blood sugar levels in healthy mice never exposed to artificial sweeteners by transplanting gut bacteria from mice who had been fed saccharine.
Turning to a group of nearly 400 people, the researchers found that long-term users of artificial sweeteners were more likely to have higher fasting blood sugar levels. They were also more likely to have signs of impaired glucose processing, compared with people who don't normally use such sweeteners.
In a small follow-up experiment, the researchers tested blood sugar levels of seven people who don't normally consume artificial sweeteners. The researchers found that four of these people had higher blood sugar levels after consuming the U.S Food and Drug Administration's maximum recommended daily amount of saccharine for six days straight.
The red emphasis is mine, of course. This raises a question in my mind — since the brain runs on glucose, could this impairment of the ability of the body to properly process glucose result in possible long-term brain damage?
It's not nice to try to fool Mother Nature, and the artificial sweetener industry has been playing that game for way too long, IMO.
