Blue berries have the same worth as that of red wine, according to a group of researchers at Oregon State University. While red wine improves the immune system of a person, the "berries" have also promised the same.

It is the compounds present in the two products that indirectly help maintain good health. Red grapes and red wine contain resveratrol, whereas blueberries have pterostilbene. The activity of human CAMP gene or cathelicidin antimicrobial peptide gene is raised by the two when these blend with vitamin D.

Since, the gene is included in immune function. Therefore, its increased activity boosts the immune.

A total of 446 compounds were examined with an aim to test their potential to improve the immune system. Adrian Gombart said that only the aforementioned two compounds showed a promise in the context.

"Their synergy with vitamin D to increase CAMP gene expression was significant and intriguing. It's a pretty interesting interaction", said Gombart, college of science's associate professor.

It was not for the first time that the impact of resveratrol has been tested. Many studies found it beneficial for cardiovascular health and reducing inflammation. But, the latest study is the first to show `berry-immune' relationship.
