Seniors who are concerned about taking preemptive aging measures to improve their senior health can get an immune system boost by implementing some simple changes in their diet. This year in May an article appeared in a leading publication dedicated to immunity that reported on the benefits for the immune system due to adding fiber to the diet. The fiber used in the lab tests included both soluble and insoluble fiber that was added to the diet in the form of citrus pectin over a period of six weeks. In the tests the subjects that had received the added fiber were 50% less susceptible to an induced bacterial infection and recovered about 50% faster than those that lacked the added fiber in their diet.
The researchers traced these benefits for the added fiber to changes in the response of immunity cells to the challenge of a bacterial infection. Without the added fiber the immunity cells tended to be pro-inflammatory, but by adding the fiber the immunity cells became more anti-inflammatory. The immunity cells that were more anti-inflammatory were better able to fight the bacterial infection. This is good news for seniors who want to get an immune system boost, in order to improve their senior health, because they can add a number of popular foods to their diets to increase the fiber in their diet. Foods containing soluble fiber include apples, nuts, seeds, oats, barley, citrus fruits, strawberries, and carrots. Supplements in the form of powders are also available.
