A study was mentioned in the Times a few days ago. This claimed that people who ate more fruit and veg were found to be more likely to have slower progression. A short piece of the article is below.
'Men from the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) study were asked to list the vegetables, fruits, nuts, seeds, meat and dairy they ate each day.
The team split the men into groups based on the amount of plants they ate. The group that ate the most consumed an average of nearly two more servings of fruits and vegetables, about one more serving of whole grains and one less serving of dairy each day than the group that who ate the least.
The scientists then measured how long it took for the disease to progress in any way. Of the 2,000 men taking part, 190 experienced some form of progression with their cancer during the period of the study.
The men with the highest levels of plants in their diets were found to have a 47 per cent lower likelihood of the disease progressing further when compared with those who ate the least amount of plants.
The researchers said that larger-scale studies were needed to inform policy and recommendations for those receiving a cancer diagnosis.'
I keep meaning to look for more information but haven't got round to it.
