To boost your immune system, try making one of our fiber-rich recipes. These fiber-rich recipes all contain soluble fiber, which is most often found in oats, apples, pears, beans, citrus fruit, carrots and barley. In one study, mice that ate a diet rich in soluble fiber for six weeks recovered from a bacterial infection in half the time it took mice that chowed on meals containing mixed fiber. Try one of our delicious, fiber-rich recipes to boost your immune system, such as Chicken Thighs with Pear & Leek Sauce or Wild Mushroom & Barley Risotto, to help you stay healthy.
