See what research says about the health benefits of eating kimchi and other fermented foods.
Refrigerated raw sauerkraut, Korean kimchi, tempeh, kefir, and yogurt–these fermented foods all have something healthy in common. They harbor live active cultures of “good” bacterial strains that can keep the gut robust and strong. In fact, studies suggest these probiotic foods might do everything from boost mood to stimulate the immune system to fight cancer. Some benefits are exaggerated, so here’s a look at where the research stands. (Shopping tip: pasteurization kills “good” bacteria so unrefrigerated jars of sauerkraut on supermarket shelves aren’t probiotic-rich.)
Immune Booster: Yes.
Scientists estimate that over 100 trillion microbes reside in the large intestine of adults. Since the gut accounts for the largest part of your immune system, keeping the gut populated with a healthy balance of “good” bacteria will keep the immune system functioning optimally.
