Probiotics popularity on the rise

Current research suggests that allergies and asthma, among other illnesses, may start in the gut when the delicate balance of microflora get out of whack. The intestines are lined with millions of "healthy" bacteria that promote that balance and aid in digestion. These healthy bacteria are being closely investigated to find out if ingesting them -- through probiotic products -- may improve a person's health.

Probiotics are popping up everywhere. Yogurts, dairy products, even baby formulas are infused with these live cultures and sold with labels that suggest they can do everything from improving your immune system to regulating your digestive tract. While health experts say that probiotics may be able to do those things, according to this article, the science behind them isn't quite that solid yet and more research is needed.

Luckily, while we wait, they also say that eating products that contain probiotics is generally safe. My gut (no pun intended) tells me that research will come out on the side of probiotics. What do you think?
