Black Rice Anthocyanin in Mixed Meals: Influence on Postprandial Glycaemic and Lipid Responses Among Healthy Individuals

Singapore24 participantsStarted 2019-09-16

Plain-language summary

The diabetes epidemic is a pertinent concern globally. The prevalence of this metabolic disease among adults had been disclosed by the World health Organisation (WHO), reporting a total of 422 million diabetic adults and 3.7 million diabetic deaths in 2016, with Asian countries contributing more than 60% of the world's diabetic population. Due to its economic and social repercussions, preventive strategies are implemented at a population level. The implementation of a diet low in glycaemic index (GI) has been widely adopted as part of diabetes management strategies to prevent and control Type 2 Diabetes Mellitus (T2DM) as the consumption of food with low GI has shown to improve glycaemic control, lipid profile, and reduce systemic inflammation. Other strategies include adopting an active lifestyle and the consumption of functional foods. In lieu of this, the composition of food products may be altered by incorporating edible plant-based functional components with carbohydrase-inhibiting properties. Black rice has been proposed as a viable source of functional ingredients, namely anthocyanins, not only because of its potential benefits to health that has been established by numerous in-vitro studies, but also it is easily sourced for in Asia as it is widely cultivated. In this study, black rice anthocyanin-fortified bread serves as a replacement to white bread as the staple to the subject's diet, in a mixed meal setting. The fortified bread is hypothesised to improve glycemic responses over white bread, offering a lower GI food alternative to the conventional staple.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
