Artificial sweeteners can turn healthy gut bacteria into pathogens
UK researchers have found that sugar substitutes such as saccharin, sucralose, and aspartame – found in soft drinks and processed foods – can cause beneficial bacteria in the intestines such as E. coli (Escherichia coli) and E. faecalis (Enterococcus faecalis) to become pathogenic, or disease causing.
“Our study is the first to show that some of the sweeteners most commonly found in food and drink – saccharin, sucralose and aspartame – can make normal and ‘healthy’ gut bacteria become pathogenic," said Dr Havovi Chichger, a senior lecturer in biomedical science at Anglia Ruskin University (ARU).
“These pathogenic changes include greater formation of biofilms and increased adhesion and invasion of bacteria into human gut cells. These changes could lead to our own gut bacteria invading and causing damage to our intestine, which can be linked to infection, sepsis and multiple-organ failure.
