Smoking and Probiotics?

In the British Journal of Nutrition, researchers discovered that the consumption of probiotics, microorganisms that provide health benefits to its hosts organism, help boost up the immune system of smokers by increasing NK activity. NK, natural killer cells, are lymphocytes that attack and kill harmful cells in the human body, i.e. tumor and virus cells. Although probiotics may assist in improving the immune system of smokers, this does not completely stop or reverse the negative effects of smoking. In fact, this research only emphasizes how much of a negative impact smoking has on the human body by demonstrating how susceptible smokers are to infections and diseases.
