Like yogurt, those foods are packed with probiotics, the good bacteria that live in your gut. For example, consider kimchee, the Korean vegetable dish. Research suggests that the probiotic bacteria that keep kimchee and similar foods from spoiling also have health benefits, including improved immunity and good digestive health.
What to buy or skip Shop the refrigerator case, where you’ll find fermented foods like yogurt and kefir as well as sauerkraut and pickles. (The shelf-stable versions aren’t fermented, so you can skip those.) Also look for a label that says the food has “live” cultures, which need refrigeration to stay active. Fermented foods that are heat-treated or pasteurized lose the good bacteria along with the bad.
Are these hot new health food trends actually healthy?
