Bacteria is the hot additive for many healthy foods

When you hear of bacterial contamination, most of us think that is a bad thing. There are good types of bacteria that should be eaten regularly, however. Most yogurt contains live bacterial cultures, for example. Without them, there would be no yogurt as it is today.

These types of "body friendly" bacteria are making their way into all kinds of products as the public buzz has caught on strong -- and in 2006, we started seeing product labels that featured the kinds of bacteria were in the accompanying product.

Examples? Bacteria such as L. reuteri listed on Stonyfield yogurt, L. casei on DanActive drinks and Bifidobacterium on Activia yogurt -- and that's just for starters. In fact, a consumer trend company recently stated that products with live bacterial cultures are so popular that they now rank among "the top five foods that people say they want to add to their diets." So, the next time you're choosing that whole-grain cereal, pick up some bacteria-infested yogurt as well.
