Glycemic load may fix the issues the glycemic index brought up but that does make it the most effective way of keeping blood sugar in the healthy range. To control blood glucose levels, a person needs to eat a consistent amount of high fiber carbohydrates throughout the day. Glycemic Load does not teach how to do this. Counting carbohydrate grams is the only real effective way to control blood sugar for someone with diabetes.
For a healthy person, glycemic load is not as important to track. It is best to choose high fiber carbohydrate foods such as whole grain breads/cereals, and fruits/vegetables for someone with and without diabetes. If you are healthy, you do not need to worry about how carbohydrates affect your blood sugar levels. Your only focus needs to be on prevention by maintaining a healthy weight and eating a wide range of nutrient dense foods. This will reduce the risk of a healthy person developing diabetes and other related health problems.
