We have long been fighting bacteria with a whole host of anti-bacterial sprays, soaps, and sanitizers. But when it comes down to it, there is no escaping the 100 trillion bacterial cells that live with us all the time on our skin, in our mouth, and in our intestines.

Some of the newest scientific research points to the benefits of the bacteria that live inside all of us. It turns out that bacteria can play a critical role in fighting obesity, diabetes and infections and it can also help keep our immune systems strong. 

The power of good bacteria is a topic that Kara Miller has been exploring for the forthcoming edition of Innovation Hub, produced by our partner WGBH in Boston. Miller joins The Takeaway to explain why certain kinds of bacteria are actually good for us.
