The Benefits of Probiotics
An Immunity Boost?
Some research suggests that when “good” bacteria reach the lower intestine, they not only suppress the growth of “bad” bacteria but also might activate the immune system to fight off diseases in other ways. But studies showing a clear boost to the immune system are few. In one study of 33 healthy young women, both “regular” yogurt and so-called “probiotic-fortified” yogurt (which contained added beneficial bacteria cultures) were found to boost T-cells, key players in the body’s defenses against viruses and other pathogens. But it’s a long way from findings like those to “assuming that by loading up on yogurt—or sauerkraut or kimchi—you can boost your immune system enough to fight off something like the H1N1 flu,” says Barry Goldin, Ph.D., professor in the department of Public Health and Community Medicine at Tufts University School of Medicine in Boston. Fortifying yourself with a daily dose of fermented foods can’t hurt, says Goldin, “but if you want to beat the flu, get vaccinated.”
