The original inventor of the PepsiCo-owned sports drink Gatorade has died at the age of 80.

The nephrologist Dr J. Robert Cade, who made the drink to rehydrate athletes, died yesterday (27 November) in Gainesville, Florida.

Cade, who was survived by his wife, six children, 20 grandchildren and eight great-grandchildren, first concocted the beverage for footballers to replenish carbohydrates in the form of the sugars sucrose, glucose, and electrolytes.

Other inventions of Cade's have included designs for football gear and gadgets for polio sufferers.
