The microbes in your gut not only help your body digest food, but they also help regulate your metabolism and your immune system. In fact, almost seventy percent of your immune system is in the gut. Eating fermented food (think bio-live yogurt, miso, kimchi, kefir, sauerkraut) popping a probiotic or increasing dosage if you are already on one boosts the level of good bacteria in your gut. These good bacteria influence your body’s T cells, the crucial white blood cells that help power your immune system. They also help reduce inflammation which prevents infection.
Practical Tip: Eat at least one portion of fermented food each day.
