Comment: 

It is well known that having a diet which is deemed High GI (Glycaemic Index) can be bad for the health. There are many books on the subject even to help people to maintain a lower GI diet with minimal effort. This can help to lower your chances of being affected by diabetes and heart disease.

There has recently been a review of these theories and also on the quality of data that has been used in the past. Read the research to find out more about how a low GI diet could improve cognitive function and your responses to exercise.
