In Britain, bowel disorder is suffered by about 120,000 people. In this kind of disorder, intestines can become painfully inflamed and this leads to vomiting, diarrhoea and weight loss.

Scientists have stated that this condition can be improved by certain types of soluble fiber as they can avoid the bacteria from sticking to the gut's walls and this can lead to a reduction in the progress of the disease.

A marked effect from soluble fiber from plantain and broccoli was found and they are already known as 'superfood' for its abilities to fight cancer and prevent furring of arteries.

The lab study was led by Prof Jonathan Rhodes, a gastroenterologist at Liverpool University.

A common type of E coli bacteria to lab-grown bowel lining 'microfold' cells was added by Rhodes and his team, after this soluble fiber from various vegetables and fruits were taken and tested the cells with them.

Prof Thodes said,"Soluble fibre might have a beneficial effect by blocking adhesion to the intestinal lining of potentially harmful bacteria."

The effect is being looked in people by a clinical study that is now underway.
