A group of scientists at the University of Lausanne in Switzerland had came out to reveal through the experiment they carried out on mice that the high and low fibre diets altered the types of bacteria living in the guts of the mice.
Good bacteria which can munch on soluble fibre, the type found in fruit and
vegetables, were found to flourished on the high-fibre diet and they in turn produced more short-chain fatty acids which is the type of fat, absorbed into the blood.
Accordingly, the scientists said 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.
Their report argued that a dietary shift away from fibre in favour of processed foods may be involved in rising levels of asthma.
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 fibre.
Consumers are encourage to try and go for foods that are high in fibre against the ones that are low in fibre. High fibre foods are good for the overall benefits of the body from lowering high blood pressure to diabetes and many more.
