A recent study conducted at the Weizmann Science Institute suggests that artificial sweeteners may trigger health problems instead of benefiting people. This is important because not only is saccharin in artificial sweeteners, but it is also found in salad dressings, vitamins, and in low/zero calorie items we often eat.
Previously, sweeteners were known to pass through the gut undigested, therefore allowing people with health issues to use the sugar substitute. Recent tests on mice and humans found that saccharin actually interferes and alters microbiota bacteria found in the gut and small intestines, leading to serious conditions such as obesity and diabetes.
Mice were monitored for 11 consecutive weeks when given drinking water doped with saccharin and the results showed they had abnormally high levels of glucose in their bloodstream. When food is digested it is broken down into glucose, the most common carbohydrate, and then enters the bloodstream to either be used as fuel or stored. When glucose metabolism is blocked, the blood glucose level is high. The test was repeated with mice on high-fat diet and the results were the same, showing that the saccharin had the same effect irrespective of the animal’s weight. Four of seven humans that ate a high-saccharin diet were also found to have an impaired glucose metabolism.
Why the microbiota are affected is still unknown as the test is preliminary, but the conclusion has been made that certain saccharin sugar substitutes are not simply passing through the intestines.
