Using glycaemic index (GI) is not a foolproof method of achieving optimal glycaemic control.
Limitations of using glycaemic index (GI)
So, is it ok to focus on glycaemic index alone?
"Relying and focusing on GI alone is not a foolproof method to achieving optimal glycaemic control. Focusing on GI alone could lead to your diet being high in fat and calories, and being unbalanced," says Ms Kala Adaikan, Senior Principal Dietitian from the Department of Dietetics at Singapore General Hospital, a member of the SingHealth group.
This is because GI does not consider total macronutrient intake. It is the total amount of caloric intake that leads to weight gain and increased insulin resistance, and makes it harder to achieve optimal glycaemic control. In addition, it may increase your risk of heart disease.
Monitoring the total amount of carbohydrates you consume has a far greater and positive impact on overall blood glucose control than focusing on GI alone. Try not to exceed your carbohydrate requirements for the day.
