Soluble Fiber May Boost Your Immune System

There are two main types of fiber, soluble and insoluble. Both are found naturally in plants and are important for digestion and the prevention of conditions such as diabetes, obesity, and heart disease. Soluble fiber has been shown to have a beneficial effect on blood-sugar levels and cholesterol. Now, research shows soluble fiber also has a positive effect on the immune system. Gregory Freund, M.D., of the University of Illinois, said soluble fiber changes immune cells from being pro-inflammatory warrior cells to anti-inflammatory peacekeeper cells. In short, the fiber stimulates the body’s T-cells, which fight infection. Sources of soluble fiber include oatmeal, lentils, apples, oranges, pears, strawberries, nuts, flaxseed, beans, cucumbers, celery, and carrots. The FDA recommends 28 grams daily for women and 36 grams for men. More here and here.
