The helpful bacteria provide a low-intensity state for the white blood cells, so they can work better when bacteria enters the body.

ReplyDeleteIn a study funded by the US Public Health Service, Thomas Clarke and Jeffery Weiser uncover many interesting facts about bacteria. Their studies show that by being exposed to "good" bacteria your immune system has a better chance of surviving bad bacteria. Their studies suggest that antibiotics turn off the bodies already equipped army. Eating foods with "good" bacteria could help counteract sickness or antibiotics. On a test they performed on mice, the data showed Nod1, something used to treat human neutrophilis, diminished the immune system of a mouse living in a germ-free environment. Then re-exposure to the normal environment, their immune system was restored.
