Changing diet may reduce asthma symptoms
People with asthma may be able to improve their symptoms by changing their diet, according to a new study.
Previous evidence has shown that gut bacteria have a significant impact on the immune system. In a new study from the University of Lausanne in Switzerland, researchers examined how changes in diet affected the bacteria living in the guts of mice. Their findings showed that a high-fiber diet allowed gut bacteria to produce certain fatty acids which led to more resistance to lung irritation, a symptom of asthma. When the mice were fed a low-fiber diet, they showed less resistance to lung irritation.
If a high-fiber diet has similar effects in humans, people with asthma may benefit from eating high-fiber foods such as fruits, vegetables and whole grains, scientists said. However, it is unknown how much fiber and what specific sources would improve asthma symptoms in humans.
The researchers said additional studies are being conducted to investigate the role of diet in reducing lung inflammation.
