Peulvruchten tegen borstkanker*

Uit een grootschalig onderzoek blijkt dat peulvruchten zoals bonen en linzen bij regelmatige consumptie, 2x per week, de kans op borstkanker wel met 24% kan verlagen.  

Beans and lentils may reduce breast cancer risk

People with breast cancer should include beans and lentils in their diet, say researchers after finding that high levels of these dietary flavonols are associated with a decrease in breast cancer.
Dietary flavonols, the most common of which are quercetin and kaempferol, have previously been reported to reduce cancer. Dr Clement Adebamowo and colleagues therefore investigated the effect that of foods rich in these, such as tea, onions, apples, string beans, broccoli, green pepper and blueberries would have on the risk of breast cancer.
They analysed data for 90,630 premenopausal women aged between 26 and 46 years, over an 8-year period, during which time 710 cases of breast cancer were recorded.
Overall, flavonol was not associated with the risk of breast cancer. The individual flavonols kaempferol and quercetin were also not found to protect against the cancer.
However, when flavonol-rich foods were looked at in detail, the results showed that women who consumed beans or lentils twice a week were 24% less likely to develop breast cancer than women who consumed them less than once a month. A comparable effect was not seen for the other food types.
“While we found no overall association between intake of flavonols and risk of breast cancer, the protective effect evidence with bean or lentil intake merits further evaluation,” the researchers summarise in the International Journal of Cancer.
However, further research is needed to "clarify the flavonoid content of foods and their bioavailability," they say.
