What Are Probiotics? Probiotic Supplements, Foods, Uses, Benefits

Fewer colds and coughs

Yogurt (or the probiotics it contains) is one of the immunity-boosting foods you need to fight off colds and flu. In an analysis of 10 studies, taking probiotic supplements cut the number of upper respiratory tract infections by 12 percent and reduced the number of people who had at least one bad cold. Dr. Lipman says that 70 percent of our immune system is housed in our gut, which is why it’s so important for overall health. According to Zuckerbrot, beneficial bacteria creates an acidic environment that’s inhospitable to harmful bacteria.
