Clinical Trial Summary

Postprandial hyperglycemia or rapid rise in blood glucose is defined as a blood glucose level>7.8 mmol/L (140 mg/dL) 1- 2 hours after consumption of food. It is associated to the development of diabetes among healthy individuals and a risk factor for the onset and progression of microvascular and macrovascular complications among diabetic patients. In Ramadan, postprandial hyperglycemia is often observed after the iftar (fasting break after sunset). The frequency of eating normally decreases during Ramadan, however, the energy intake remains questionable because dietary practices during Ramadan are influenced by local culture, economic status and individual dietary behaviors. In many Muslim societies including Malaysia, Ramadan has known as a month of feasting. Iftar meals are typically high calorie, carbohydrate-rich and usually sweet food resulting in rapid rise in glucose after the meal. This poses a challenge for the people with diabetes to manage their glucose level. D-allulose (a C-3 epimer of D-fructose) is a rare sugar and reported to have several health benefits, such as suppressing a rise in postprandial glucose levels. There is still a scarcity of research on patients with diabetes. As a result, the current clinical study sought to investigate the effect of supplemental D-allulose on participants with type 2 diabetes who consume real-meal calories during Ramadan iftar.

Description:

D-allulose (a C-3 epimer of D-fructose) is one of the rare sugar types with zero calories, has 70 % sweetness as sucrose, and occur in a small quantities in nature. Extensive basic and clinical studies have reported beneficial outcomes to human health, includes improve hypoglycemia, reduced postprandial hyperglycemia, hypolipidemia, and antioxidant. D-allulose can be taken up to 0.5 g/kg daily will no side-effect on the human body. The U.S. Food and Drug Administration (FDA) has declared that D-allulose is Generally Recognized As Safe (GRAS) for use as a food ingredient and with other sweeteners. Previous clinical studies on D-allulose had shown an effective glucose suppressive effect after the meal, mostly in healthy individuals and pre-diabetics. There is still a scarcity of research on patients with diabetes. As a result, the current clinical study sought to investigate the effect of supplemental D-allulose on participants with type 2 diabetes who consume real-meal calories during Ramadan iftar (breaking fast at sunset). This was a non-randomized intervention study, which involved a single-arm group, and conducted during Muslim fasting month (Ramadan) between 13 April to 12 May 2021. The protocol required continuous 14 days of Ramadan and it was divided into two consecutive periods; began with first 7-day of control period and followed with a consecutive 7-day of D-allulose period. At the D-allulose period, 8.5g of D-allulose was consumed before the iftar meal. The FreeStyle Libre Pro Flash Glucose Monitory system (CFGM) was used to measure the glucose values.

Intervention

Other:
• Control period
first 7 days, participants consumed normal meal during iftar (breaking the fast at sunset) participants did not allow to have added sugar/ sweetness drinks before the iftar meal flash continuous glucose monitoring system (FreeStyle Libre Pro) was used to measure the glucose food diary was used to record the iftar meal

Dietary Supplement:
• D-allulose period
[started after 7 days of control period], participants continued with D-allulose period for 7 days continuously participants consumed 8.5 g of D-allulose, (dissolve in plain water normal) before start the iftar meal participants did not allow to have added sugar/ sweetness drinks before the iftar meal flash continuous glucose monitoring system (FreeStyle Libre Pro) was used to measure the glucose food diary was used to record the iftar meal a questionnaire (multiple choice anwers) was used to record the side effects of D-allulose
