Diet and gut bacteria play a huge role in keeping our immune system healthy. Diet influences gut bacteria. The relationship between our diet and gut bacteria regulates how our immune cells behave. Although there is not a specific diet for the coronavirus, dietary choices are important for immune system support.  A balance of foods that contain prebiotics and probiotics are essential for a healthy microbiome. Probiotic foods contain good bacteria. Prebiotic foods contain fiber that gut bacteria feed on.  Important nutrients that support the immune system include vitamins A, C, and D, and the mineral zinc. 

  • Probiotic-rich foods: Yogurt, kefir, kombucha, tempeh, kimchi, miso, sourdough bread, sauerkraut
