Glycemic Index (GI) – Is it overrated?
For anyone living a healthy lifestyle, no matter what goals are trying to be achieved, people should, at least, be aware of the GI of common foods / ingredients.
So what is the Glycemic Index?

The index was originally developed in the early 1980’s solely to aid those suffering from Diabetes. A sharp and dangerous rise in blood sugar could cause serious problems for those who have diabetes. It has now also being used by those looking to lose weight and maintain a steady stream of energy for the athlete.
What is the GI measured against?
Confusingly there are two different measures. One uses white bread as a standard. The other scale uses glucose at the standard, with glucose rated as 100. Fortunately the glucose measure is the most commonly adapted.
So are all foods that measure a high GI bad?
This question mainly depends on your goals. It is not necessary to block all high GI foods. In fact one could manipulate high GI foods to quickly obtain energy or replenish fuel after an extensive workout. The key is once again moderation. Having a high GI food once in a while shouldn’t cause any long term effect to reaching your goal. Also a high GI food may have a low GI Load.
