Brief summary

It is important to bring the blood glucose levels of those with type 2 diabetes mellitus (T2DM) back to normal levels as this can stop the condition from worsening and prevent other conditions that are related to T2DM from developing. One way to maintain healthy blood glucose level is the use of the glycaemic index (GI), which ranks food according to how the body responds to its carbohydrate content. Low GI foods corresponds to low increase in blood glucose levels. Calamansi is a citrus that is believed not to induce an increase in blood glucose levels. Since beverages from calamansi are available and diabetes is a health concern in the community, it is important to investigate the effect of consuming this drink. Finger prick blood were tested in order to obtain the blood glucose levels for calculating the GI for the calamansi drink.
