A blend of fruit juices, including grape, cranberry and blackcurrant, may have benefits for the heart, research suggests.
French scientists tested the blend on pig arteries in the lab, and found it caused artery walls to relax. It remains to be seen whether fruit juices can improve vascular health, they report in a scientific journal. The study adds weight to evidence fruit and veg reduces heart disease risk, says the British Heart Foundation.
The researchers looked for a chemical called polyphenol in fruit and berries. They found the most active fruits included blackcurrant, blueberry, aronia (choke berries), cranberry, lingonberry and grape.
Commenting on the study, Tracy Parker, heart health dietitian at the British Heart Foundation, said: "This research adds more weight to evidence that eating fruit and vegetables is good for us in terms of reducing our risk for heart disease."
