Nutritional formula drinks are widely consumed in Asia especially by those having chronic illnesses such as diabetes. Therefore, gauging the impact of nutritional formulas on blood glucose levels is very important. Asia is home to three predominant ethnic groups- Chinese, Malay and Indians. It is still unknown if the blood glucose response to nutritional formulas differs between ethnic groups. Therefore the aim of this study is to observe if there are ethnic differences in the blood glucose response to nutritional formula drinks.
