Sick of Getting Sick? Embrace Your Inner Bacteria!, NPR:

Over there, one type of bacteria has settled into a tidy corner of your intestine and is helping to synthesize vitamin K from last night”™s dinner. That”™s an important blood-clotting substance. And without the help of a neighboring microbe, the broccoli you downed would be no more digestible than a fallen log.

Right this minute, in the moist, warm grottos throughout your body, encounters with friendly bacteria are teaching your immune cells how to recognize dangerous invaders. The ability to distinguish friend from foe is crucial to keeping you healthy. And by acting as a thick ground cover, these benign bacteria crowd out truly noxious germs — salmonella, say, or dangerous versions of E. coli.

The title of NPR’s article is a bit misleading as the focus of the story is really on the potential harm from antibiotics. Bacterial Evolution in Yogurt provides some additional information on the benefits of bacteria.

    All yogurts are not created equAL, and some may have killed and not live bacteria. Similarly, not all commercial probiotic brands (capsules etc)are created equal. There is a wide diversity in the strains of bacteria and their concentration in different formulations thus affecting their benefit potential.

    I find this area and this study fascinating. I”™m not exactly sure why this study and the incredibly significant positive bacteria for human life news doesn”™t get more notice. Oh well I guess there are not cool pictures of robots or scary stories of potential threats…

    I fully agree with ‘docwrite’. If you buy probiotic supplement as with everything, make sure that the brand is trustworthy. Probiotics is indeed good for human health but make sure you give your body the right kind of bacteria.
