Scientists have created what they claim is a fruit cocktail with an ideal blend of 13 different juices that can lower one's risk of heart disease and stroke.
The "super smoothie" cocktail contains grapes, apples, blueberries and strawberries - and it tastes good. However, there are exotic additions like lingonberry and acerola, a red cherry-like fruit that has 30 times more vitamin C than orange juice.
The final ingredient of the smoothie is aronia, or chokeberry, an American blackberry once described as the "healthiest berry in the world", say the French scientists.
Blends of 13 different purees and juices were analysed in a laboratory for their effects on pig arteries. But, the finished recipe was selected after tests by 80 volunteers, the Daily Mail reported.
In tests, heart artery walls relaxed when they were exposed to the fruit juice cocktail.
The scientists say in a human, this would boost the flow of blood to the heart and ensure it got a healthy balance of nutrients and oxygen.
