Compound Found in Blueberries Rivals Resveratrol for Colon Health
Researchers from the National Kaohsiung Marine University in Taiwan recently found that an extract from the Indian kino tree called pterostilbene may be more effective than resveratrol for improving colon health. Their findings were published in the March 2011 issue of the Journal of Agricultural and Food Chemistry (JAFC).
For the study, mice were exposed to a compound that is known to induce tumor formation in the colon (azoxymethane). They were then divided into two groups. One group was given a pterostilbene supplement and the other group received a resveratrol supplement.
When the researchers compared the two groups, they found that while both compounds provided cancer prevention effects, the pterostilbene was more effective at reducing the response to the azoxymethane compound.
The mice who received the pterostilbene saw decreased inflammation and increased expression of various antioxidant enzymes.
Pterostilbene is found in blueberries and grapes. Previous animal studies have shown its potential to lower cholesterol and triglyceride levels and to protect against cognitive decline.
The results of this study, however, should in no way undermine the benefits of resveratrol which has been shown to provide significant heart health benefits, lower inflammation and reduce the risk of Alzheimer's.
