Apples and onions may slash pancreatic cancer risk

Apples and onions may slash pancreatic cancer risk
"A diet rich in flavonols from foods such as onions, apples and berries may cut the risk of developing pancreatic cancer by about 25 per cent...The results, published in the American Journal of Epidemiology, indicate that the benefits may be even more pronounced amongst smokers, with a risk reduction of over 59 per cent...The reason for the apparent added benefits for smokers was presumed to be due to smokers being at an increased risk of pancreatic cancer...The researchers also stated that theirs is the first study to examine prospectively specific classes of flavonols (quercetin, found in onions and apples; kaempferol, found in spinach and some cabbages; and myricetin, found mostly in red onions and berries) and pancreatic cancer risk. "...Of the three individual flavonols, they report that kaempferol was associated with the largest risk reduction (22 per cent) across all participants. The interaction with smoking status was statistically significant for total flavonols, quercetin and kaempferol... the researcher indicated that the anti-cancer effects of these compounds may lie in their ability to the inhibit cell cycle, cell proliferation and oxidative stress..."
