  • Scientists unravel probiotics gut defence

    Publish Date: 2011-02-01

    Author: Carl Holm

    Australian and Japanese scientists have uncovered the mechanism by which probiotic bacteria protect the gut from E. coliinfection. Over the last few years, scientists have found that lactic acid bacteria and bifidobacteria have health-promoting effects, but until now exactly how they did this wasn't fully understood. The human gut is home to a wide variety of microbes that have beneficial effects, including aiding gut function and protecting against illness and infection. One of these, a probiotic known as Bifidobacterium, modulates host defence responses and protection against infectious diseases.

  • Probiotics: The Lowdown

    Keen to join the 'culture club'? Read these tips first, says Bonnie Cleaver. Here's a fact you'll want to read sitting down — your digestive tract is home to more than 100 trillion live bacteria, weighing up to 2kg — that's about 10 times the number of cells in your body. Getting enough "good" bacteria, called probiotics, supports digestive health, but that's not the only reason you should consider taking them. Probiotics also bolster immunity, with around 70 percent of immune cells located in the gut. While it's still early days for research, science is also linking probiotics to exciting benefits like relief from lactose intolerance, eczema, inflammatory bowel disease, UTIs and thrush. But with the explosion of probiotic foods and supplements on the market, it's tricky to pick the best one for you. Read on for expert advice on how to make the most of the good bugs.
