So don't expect to preform to your maximum capabilities without a regular supply of carbohydrates. The best carbohydrates are those that are also packed with vitamins and minerals. They are important for your general health and are an important part of the enzyme processes that allow the energy contained in the carbohydrates to be released. Sugar, soft drinks, fruit juice, honey, jam, topping, lollies etc are carbohydrate foods too, but contain very little vitamins and minerals. We now know that these basic assumptions were wrong - different carbohydrates are digested at different rates, which have to be determined by scientifically testing each food item individually.
Some carbohydrates are better than others at different times of the competition.
It all has to do with how quickly they are digested to release glucose. Carbohydrate foods with a high GI rapidly release the glucose so are best to eat when you need energy fast. During the game - have foods with a high GI to give you a quick energy boost. Drink plenty of fluids before, during and after the game. If this is not possible, try to have a high carbohydrate snack one to two hours before you tee off.
