Fruits, vegetables and whole-grains might be an unlikely treatment for asthma according to animal studies.
Tests on mice, published in the journal Nature Medicine, showed that a high-fibre diet could reduce inflammation in the lungs. The extra fibre changed the nutrients being absorbed from the gut, which in turn altered the immune system. The researchers argue the shift to processed foods may explain why more people are developing asthma.
The airways are more sensitive to irritation and more likely to become inflamed in people with asthma. It leads to a narrowing of the airways that make it harder to breathe. However, a possible solution may lie in another organ, the gut, and the bacteria which live there.
The cells of the human body are vastly outnumbered by the trillions of microbes that live in and on it. There is growing evidence that these bacteria have a significant impact on health.
