In the Daily Express, the Guardian, The Times, The Telegraph and The Independent today a study has been reported that appears to link saccharin intake with obesity and diabetes. In the study on mice, high saccharin intake resulted in high blood sugar levels by altering gut bacteria.
Principal Dietitian at St. George's Hospital, London, Catherine Collins responded with "Suggesting sweeteners like saccharin may cause problems with blood sugar is bound to generate worried interest from users. But if we separate the results from reality there's no real human story here at all", adding that because the diet of the test mice was so different from the average human, the result could not be reliably extrapolated.
