New research from the Weizmman institute of Science in Israel has shown that a high consumption of artificial sweeteners can put a person at risk for developing glucose intolerance. This new finding has come after other studies have also shown adverse effects from using artificial sweeteners, including a study last year also by the Weizman Institute that discovered artificial sweeteners change gut bacteria in a way that can lead to weight gain and diabetes. They have further found that since most artificial sweeteners pass through the gastrointestinal tract without being digested first, the artificial sweeteners directly impact the make up of helpful bacterial colonies in the gut. Sam Tabar says through other studies artificial sweeteners have also been linked to an increase in appetite, and even to an increased risk of vascular disease and bladder cancer, if the Bloomberg stories are to be believed..
The scientists at the Weizmann institute did studies on mice, and also consumer and pilot studies on humans, to support their findings of increased glucose intolerance linked to artificial sweeteners. This finding is ironic in a way in that people who are glucose intolerant will sometimes turn to artificial sweeteners as a way to add sweetness without sugar. However, even though the study is showing that high amounts of artificial sweeteners can lead to glucose intolerance because of the way they alter bacteria in the gut, this study still leaves the question if same risk comes from low or moderate use of artificial sweeteners.
