Effects of kiwifruit consumption on energy expenditure, blood sugar and appetite after eating

This study will help us to understand how kiwifruit, a commonly consumed food in New Zealand, influences the way we process foods after eating. This study will also explore whether Chinese (who are more susceptible to type-2 diabetes at the same BMI) and European Caucasian responds differently to kiwifruit consumption. Learning how these mechanisms work could inform future dietary guidelines, which may help people avoid weight gain and poor metabolic health outcomes (e.g. type 2 diabetes).

You will be required to come to the Human Nutrition Unit (Mt Eden) for an initial screening visit (approximately 1 hour) to assess your eligibility. If you are eligible, we will further invite you to attend a 30-minute body composition scan, and two 5-hour Study Visits.

During the Study Visit, we will provide you with test meals, and measure your energy expenditure, blood sugar, and appetite after eating.
 

You may be eligible to take part in this study if you fulfill the following criteria:

• Between 18 - 60 years old.
• Have BMI between 24 - 40 kg/m2 (overweight / obesity).
• Have elevated fasting blood sugar level, but not diabetes. We can test this for you at no cost. 
• European Caucasian or Asian Chinese (more widely, individuals from mainland China, Singapore, Malaysia, Hong Kong and Taiwan). 
• Are willing to have blood taken as part of a clinical study.
• Can eat a wide range of foods (not vegetarian/vegan).

You will receive your individual blood test results, body composition results and up to $170 shopping vouchers as koha.
