Australian scientists find direct link between diet and immune
system
Australian scientists have found a "direct link" between what we eat
and how well our immune system operates, a breakthrough that could
explain rising rates of autoimmune disease across the western world.

Professor Charles Mackay, working at Sydney's Garvan Institute of
Medical Research, identified how fibre in the diet plays a major role in
ensuring a person's immune cells function properly, the Australian
Associated Press reports.
"This does provide a direct link for the way immune cells work with
the sort of things we eat."
This broken-down fibre was found to "profoundly affect immune cell
function", Prof. Mackay said, and without it the immune cells appeared
more likely to go awry.
Autoimmune disease refers to disorders in which a person's immune
system mistakenly attacks part of the body, causing inflammation. "When
(immune cells) go bad they cause inflammatory diseases, so asthma,
rheumatoid arthritis, inflammatory bowel disease." Prof. Mackay said.
A lack of dietary fibre could also be behind the rise in type 1
diabetes, he said.
The research suggests that having a healthy diet rich in fruits,
vegetables, grains, nuts and seeds would reduce a person's risk of
autoimmune disease.
It also helped to explain why food supplements that affect the
balance of gut bacteria were known to reduce the symptoms of some
inflammatory conditions.
Prof. Mackay said dietary fibre, or roughage, was otherwise known to
reduce the risk of cardiovascular disease and certain cancers plus it
ensures you will be regular.
