That is because and work out a fair testing assessment of the glycemic indexes out of dinner constantly have fun with 50 g away from offered carbohydrate from inside the for every single dinner. You could eat two times as of several carbohydrates inside the a food one to, such as, has a good glycemic directory out-of 50 than one which has actually good glycemic index off one hundred and also have the exact same blood glucose response.
Fundamentally, sample foods is provided to several anybody, certain that have diabetic issues, other people rather than, inside the portions containing 50 g away from available carbohydrates.
