Chewing gum and artificial sweetener could help fight viruses and bacteria

Scientists are exploring unconventional tools - like artificial sweeteners and chewing gum - to combat antibiotic resistance and viral transmission.

A new study has shown that saccharin, a widely used artificial sweetener, can kill multidrug-resistant bacteria by damaging their cell walls and boosting the effectiveness of existing antibiotics.

Normally it takes  billions of dollars and decades to develop a  new antibiotic.  But here we have a compound that’s already widely used, and it not only kills drug-resistant bacteria but also makes existing antibiotics more effective.

Researchers have also created a clinical-grade chewing gum made from lablab beans, which contain an antiviral protein that neutralises up to 95% of viruses like herpes and influenza in the mouth.

The beans are native to sub-Saharan Africa and contain an antiviral protein, which is effective against a range of viral pathogens.
