A new study that found some probiotics make certain infections worse highlights why it’s important to rigorously test probiotics before they hit the market.
Bacteria used to have an almost unanimously negative connotation. For good reason: The microscopic beings caused infections that made us ill and often killed us. It wasn’t until recently that scientists realized far more bacteria help keep us healthy than make us sick.
