altJPNN|A new research carried out by the Swiss scientists has demonstrated that certain types of food containing more fiber can protect lungs against asthma. Researchers say animal study shows that soluble fiber, which comes from fruits and vegetables, can reduce inflammation in the lungs, according to study report published in the journal Nature Medicine. They revealed that the high and low fibre diets altered the types of bacteria living in the guts of the mice. There are two types of dietary fiber from food including insoluble and soluble. Insoluble fiber, from foods like whole grains, cucumbers and broccoli, helps cleanse the bowel, clarified the study researchers from the University of Lausanne. Soluble fiber, which comes from fruits and vegetables, and is broken down by microbes in the intestines, may reduce inflammation in the lungs, they also explained.
The cells of the human body are host of the trillions of microbes that live in and on it. Many evidences show that these bacteria have a significant impact on health. Researchers also found that mice with low-fibre diets became more vulnerable to asthma. “Until recently, asthma was virtually unknown in nations where people eat a lot of soluble fiber," said the immunologist Benjamin Marsland at the University of Lausanne. “In some countries, Burkina Faso, for example, dietary fiber intake is very high and there is no development of allergies whereas in westernized countries we have an intake of dietary fiber is low and the allergies have been increasing," Marsland also noted. The study researchers are also investigating the role of diet in long-term lung inflammation such as COPD, which is set to become the world's third biggest killer. Agency/PT
