Coca-Cola is working with scientists at the University of East Anglia in a bid to prove that Coke can combat anaemia.
The soft drink company believes the fizzy drink could encourage the release of greater levels of iron from food, which is then absorbed into the body.
Iron deficiency is the cause of anaemia, a common condition where the body doesn't generate enough red blood cells.
The university is conducting clinical trials in which 16 volunteers are fed pizza with Coke, Diet Coke and mineral water. The iron levels in their blood are measured before and after they consume the products.
