'Low-fat diet reduces prostate cancer risk'

Scientists from the University of California claim the discovery is the first of its kind in a mouse model that closely mimics human cancer and are now carrying out similar trials on men - the findings of which may affect life insurance policies.
The team focused their research on fat from corn oil, which is made up primarily of omega-6 fatty acids (polyunsaturated), of which high levels are found in baked and fried goods.
One group of mice was fed a diet with about 40 per cent of calories coming from fat - an amount researchers say is typical in men eating a western diet - while the other group was fed 12 per cent of their calories from fat.
The research revealed more than a 27 per cent reduction in incidence of prostate cancer in the low-fat diet group.
"We didn't know what to expect in terms of the role of reducing dietary fat in preventing prostate cancer," said study senior author William Aronson.
"We think this is an important finding and we are presently performing further studies in animal models and conducting clinical trials in men."
According to Cancer Research UK, prostate cancer is the most common form of the disease in men in the UK, representing a quarter of all new cases.
