Probiotic May Boost Immunity in Mature Adults
As we age, our immune systems get weaker and we become more susceptible to infections. A recent study suggests that taking the probiotic B. lactis HN019 may help strengthen the immune system in mature adults.
Researchers analyzed data from four studies that were originally published approximately fifteen years ago. These studies included a combined 81 participants, between the ages of 60 and 70, who consumed either a low-fat milk fortified by B. lactis or a control daily for three to six weeks. Of the four studies, only one used a control group.
After examining the data, the researchers found that the probiotic enhanced the phagocytic capacity. That means that the participants’ white blood cells were able to destroy pathogens more efficiently.
Researchers from Miller Scientific Consulting, Inc., and DuPont Nutrition and Health conducted the analysis. It was published in the journal Nutrients online ahead of print on February 24, 2017.
B. lactis HN019 is a probiotic found in lactic acid. Previous studies suggest that it may help decrease colonic transit and improve gastrointestinal symptoms in healthy adults. It can be found in fresh yogurt, kefir, and fermented foods. It can also be taken as a supplement.
