Anti-cancer benefits of vegetables and fruit are emphasized

A diet high in fruits and vegetables, especially organically grown, may protect against cancer and heart disease and may be equivalent, in this context, with each day taking a low dose aspirin, say scientists.

Fruit and vegetables are known to contain high levels of salicylates that the active ingredient of anti-inflammatory is aspirin.

Of vegetarians is now known that a low rate of cancer, as well as higher levels of salicylates in their body. The conventionally grown fruits and vegetables treated with pesticides and which is found on many supermarket shelves has a lower level of salicylates than organically grown.

An evaluation of the potential link between cancer protection and substance found in aspirin, published in the medical journal The Lancet, says that a large number of herbs and spices also are particularly rich in salicylates. This could explain differences in international cancer grades, says the study.

The salicylates in fruit and vegetables may in fact play a greater role in protecting against cancer than the antioxidants which research to date has focused on, say the researchers. Professor Peter Elwood of Cardiff University's medical faculty, who led the investigation, said: "I think this is a very exciting area that needs to be consider reasonable depth.

"Most medical authorities for 20 years said that the antioxidants in fruit and vegetables are responsible for the protective effects. It brings us to us to ask whether the beneficial effects of fruits and vegetables because they contain salicylates, "he said.

Of salicylates, first identified in strawberries at the beginning of the 20th century, it was found that they occur naturally in a wide range of plants.

Their role in reducing the risk of colon cancer was previously studied, although the uptake by the human body from different sources, and the likely dose needed to reduce the impact on health are difficult to measure.
