Two thousand years ago, Greek athletes stuffed themselves with honey during training for the great Olympiad, aware that it could boost their energy and performance levels, writes Gloria Havenhand.
Honey contains glucose and fructose, which produce tremendous reserves of glycogen in the liver. The all-important consideration in any feat of endurance is to maintain blood-sugar levels because those with the best stores of glycogen and blood sugar will always emerge from such tests of endurance and races against time as the least exhausted and last to be fatigued.
A teaspoon of honey has 22 calories, whereas the same amount of sugar has 15. But honey is much more valuable and refuels the brain within minutes because it is almost equal parts glucose and fructose. Having a spoonful of unprocessed honey before bed can support your brain function.
