Resveratrol And Pterostilbene, In Red Grapes And Blueberries, Could Boost Immune System
Red grapes and blueberries may be superfoods for your immune system, a new study suggests.
Researchers from Oregon State University analyzed 446 different compounds, to find that only two of them had abilities to boost the immune system: resveratrol, found in red grapes, and pterostilbene, found in blueberries.
The two compounds promote health because they work with vitamin D to increase expression of the CAMP gene, known to play a role in the functioning of the body’s immune system.
Because the study, published in the journal Molecular Nutrition and Food Research, was only conducted in a lab setting and not in humans, more research is needed before saying that consuming the compounds from fruits in diet would have immune-boosting effects. But still, the idea that certain foods could potentially improve the immune system is intriguing, researchers said.
Resveratrol in particular has been fingered in other studies for its potential health benefits, especially on heart health and insulin sensitivity (though research on this is not definitive).
