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.
