Certain types of bacteria can help us digest food and may support a healthy immune system. But stressors, such as antibiotics and a diet high in processed foods, can reduce these beneficial microbes.
Fermented foods are a source of these bacteria. We don’t know yet to what extent they colonize our guts, but research suggests they may be helpful.
Some foods with live bacteria include yogurt, kefir, and certain types of sauerkraut and pickles. Other cultures eat a variety of fermented foods, such as:
Look for foods that are fermented, rather than pickled with vinegar or processed using high heat. Labels on dairy products should include live bacteria (such as Lactobacillus). Aim to regularly incorporate these foods into your diet.
