Cola drinks, such as Coca Cola and Pepsi, can cause diabetes and muscle problems ranging from weakness to paralysis, new research has discovered.
The drinks can cause potassium levels in the blood to drop, which can lead to serious muscle problems such as hypokalaemia.
Researchers from the University of Ioannina in Greece discovered that people who drank excessive amounts of cola drinks were liable to suffer problems such as paralysis. The victims made a full recovery after they stopped drinking the colas and were put on potassium drips or supplements.
One of the victims was drinking between two and nine litres of cola a day. The average consumption is less than half a litre a day.
