Is your gut bugging you? Sometimes that can be a good thing, especially when it comes to the heathful bacteria that lives in your digestive system and helps you to digest food. There are about 300 - 1000 different species of guts bugs living in your large intestine, some good, some bad. Recently you may have noticed that probiotics are all the rage, sneaking into all kinds of food, from yogurt to cereal. Last weekend I came across the pictured sticker in a promotion for phd, a new probio beverage on the market, check out their gut bug blog for more info.
