The Effects on Glycemic and Insulinemic Responses by Fruit Consumption

The health benefits of fruits and their importance in a healthy diet have long been known. Several intervention studies have included the promotion of fruit as part of the healthy diet and epidemiologic evidences have demonstrated that a diet rich in fruits is associated with the reduction in the risk of many chronic diseases, including type 2 diabetes. Such beneficial health effects of fruits could be attributed to the presence of dietary fiber, micronutrients (vitamins and minerals), antioxidants and phytochemicals found in them. However, up to our knowledge, no study has investigate the time-course effects on the co-ingestion of fruits with other food product on postprandial glycaemic response (GR) and insulinaemic response (IR). The time-course effect will be examined in this study in order to determine its optimal effect on GR and IR. The investigators also aimed to compare the effects of varying micronutrients content in fruits on GR and IR.
