Vitamins and Minerals May Lower Bladder Cancer Risk
An international team of researchers recently collaborated on a study which found that various vitamins and minerals may significantly reduce the risk of bladder cancer. The team was led by researchers from the Cancer Council Victoria in Australia.
The findings of the study were published in the December 2009 issue of the journal Cancer Causes and Control.
For the study, the researchers used a 121-item food frequency questionnaire to determine dietary intakes of various vitamins and minerals among 322 people with bladder cancer and 239 healthy individuals.
Among mature adults, high intakes of carotenoids, vitamin D, thiamin, niacin, and vitamin E were all linked to reductions in bladder cancer risk.
More specifically, participants with the highest intakes of vitamin E (at least 193.4 milligrams per day) had a 34% reduction in bladder cancer risk.
When the researchers looked at results for heavy smokers, they found that the highest intakes of vitamin E, carotenoids and niacin were associated with a 42%, 38% and 34% reduction respectively in bladder cancer risk.
Bladder cancer is most common among mature adults. This study shows that increasing dietary intakes of vitamins and minerals may be especially effective at reducing bladder cancer for that demographic.
The researchers noted that B group vitamins like thiamin and niacin and antioxidants like vitamin E showed the strongest protective effects.
Some foods high in B- vitamins include bananas, potatoes, whole grains and even beer. Vitamin E can be obtained through a number of dietary sources such as sunflower seeds, almonds and spinach.
