Loved or hated, the humble oat could be the new superfood for cancer patients as international shows a diet rich in fibre could significantly reduce radiation-induced gut inflammation.
Conducted by the , and the , the preclinical found that dietary oat bran can offset chronic gastrointestinal damage caused by radiotherapy, contradicting long-held clinical recommendations.
Gastroenterology and oncology researcher UniSA’s says the research provides critical new insights for radiology patients.
“Cancer patients are often advised to follow a restricted fibre diet. This is because a diet high in fibre is believed to exacerbate bloating and diarrhoea – both common side effects of radiotherapy,” Dr Stringer says.
“Yet, this advice is not unequivocally evidence-based, with insufficient fibre potentially being counterproductive and exacerbating gastrointestinal toxicity.
“Our study compared the effects of high-fibre and no-fibre diets, finding that a fibre-free diet is actually worse for subjects undergoing radiotherapy treatment.
“A diet without fibre generates inflammatory which are present for a long time following radiation, resulting in increased inflammation of the digestive system.
“Conversely, a fibre-rich diet decreases the presence of cytokines to reduce radiation-induced inflammation, both in the short and the long term.”
Intestinal issues following radiotherapy are problematic for many cancer survivors.
“In Europe, approximately one million pelvic-organ cancer survivors suffer from compromised intestinal health due to radiation-induced gastrointestinal symptoms,” Dr Stringer says.
“This is also commonplace in Australia and around the world with no immediate cure or effective treatment.
“If we can prevent some of inflammation resulting from radiation simply by adjusting dietary fibre levels, we could improve long-term, and possibly life-long, intestinal health among cancer survivors.”
