If you suffer from asthma, you may want to think about what you are eating. If fruits, vegetables, and whole-grains are on the list, you are on the right path! These foods are foods that provide the nutrition we require for healthy living anyway, but according to animal studies, they can also be used as a treatment for asthma.
According to the journal, Nature Medicine, it was reported that a high-fibre diet could reduce inflammation in the lungs caused by asthma. The extra fiber being consumed altered the nutrients being absorbed which also boosted the immune system. Researchers say that processed foods may offer an explanation for why more people are developing asthma than ever before.
A group of researchers at the University of Lausanne in Switzerland reported, “the high and low fiber diets altered the types of bacteria living in the guts of the mice. Bacteria which can munch on soluble fibre, the type found in fruit and vegetables, flourished on the high-fibre diet and they in turn produced more short-chain fatty acids – a type of fat, which is absorbed into the blood. These fatty acids acted as signals to the immune system and resulted in the lungs being more resistant to irritation. The opposite happened in low-fibre diets and the mice became more vulnerable to asthma. A dietary shift away from fiber in favor of processed foods may be involved in rising levels of asthma.”
The report said, “In recent decades, there has been a well-documented increase in the incidence of allergic asthma in developed countries and coincident with this increase have been changes in diet, including reduced consumption of fiber.”
Dr. Benjamin Marsland, one of the researchers, said, “some of the differences caused by high-fibre diets have already been observed in people by comparing diets in Europe and Burkina Faso. There’s a very high probability it works in humans, the basic principle of fibre being converted to short-chain fatty acids is known. But we don’t know what amount of fibre would be needed and the concentrations of short-chain fatty acids required might be different. It is early days, but the implications could be far reaching.”
