The link between Diet and Immune systems

Tying the strands together Australian Scientists have now uncovered one of the main mechanisms linking fibre in diet to the immune system.

Diet And Intestinal Bacteria Linked To Healthier Immune Systems
"The notion that diet might have profound effects on immune responses or inflammatory diseases has never been taken that seriously" said Professor Mackay. "We believe that changes in diet, associated with western lifestyles, contribute to the increasing incidences of asthma, Type 1 diabetes and other autoimmune diseases. Now we have a new molecular mechanism that might explain how diet is affecting our immune systems."

"We're also now beginning to understand that from the moment you're born, it's incredibly important to be colonised by the right kinds of gut bacteria," added Kendle. "The kinds of foods you eat directly determine the levels of certain bacteria in your gut."

"Changing diets are changing the kinds of gut bacteria we have, as well as their by-products, particularly short chain fatty acids. If we have low amounts of dietary fibre, then we're going to have low levels of short chain fatty acids, which we have demonstrated are very important in the immune systems of mice."
