MORRIS PLAINS, NJ--(Marketwired - Jul 28, 2016) - Two new research studies conducted by Professor Gary Frost and his team from Imperial College London, and funded by Diabetes UK, have shown three major beneficial effects of BENEO's chicory root fiber Orafti®Synergy1 (oligofructose-enriched inulin) in reducing the risk of diabetesi ii. The first effect helps pre-diabetic people to lower energy intake and enhance weight loss. The second assists pre-diabetic adults reduce fat content in their liver and muscle tissue and the third effect of chicory root fiber is in improving insulin secretion after a meal. Researchers concluded that (fermentable) chicory root fibers have unique metabolic effects that are of particular benefit to people at risk of diabetes.
With approximately 415 million diabetic people worldwide and predictionsiii that these numbers will rise dramatically in the coming years, the new findings are of significant relevance. Prevention strategies specifically targeted to people in a pre-diabetic state -- at the onset of developing diabetes -- are urgently needed. Diet and lifestyle changes aimed at weight loss are known to be effective but they are difficult to sustain over the long-term due to a compensatory increase in appetite and food intake. With this in mind, Professor Frost and his team explored the potential of Orafti®Synergy1 in diabetes prevention (as these chicory root fibers have shown in earlier research to reduce appetite as well as food intake and to promote weight loss in overweight adults).
In the first parallel-design study that took place over an 18 week time period, one group of 20 pre-diabetics consumed 30g of Orafti®Synergy1 daily and a control group of 19 pre-diabetics consumed a non-fermentable fiber. Both groups lost approximately 5% of their body weight during the first 9-week weight loss period (as anticipated and supported by regular dietary counseling), however the Oraft®Synergy1 group showed a sustained and significantly greater weight loss in the following 9-week weight-maintenance period (where no further support was given). This could have resulted from the significantly greater reduction in food intake observed: after 9 weeks of Orafti®Synergy1 supplementation, participants consumed about 270 kcal less in an ad libitum meal test.
This is the first time that regular Orafti®Synergy1 supplementation has been confirmed as enhancing a traditional calorie-restricted lifestyle program, in the pre-diabetic population, leading to greater weight loss.
In addition, the results showed that Orafti®Synergy1 led to a greater reduction in body fat percentage, with significant reductions in liver fat and soleus muscle fat. Liver fat is known to be a risk factor in metabolic diseases like diabetes mellitus, thus the observed lowering effect of Orafti®Synergy1 on liver fat in pre-diabetic people, independent of weight loss, provides an additional benefit in diabetes prevention.
The second study confirms the beneficial effects of Orafti®Synergy1 on weight loss and energy intake in the pre-diabetic population. Improvements in insulin response were observed with regular Orafti®Synergy1 supplementation over a six week period. In this cross-over design study, 34 participants with impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) consumed up to 30g Orafti®Synergy1 daily, or a non-fermentable fiber as control. In pre-diabetic participants with impaired fasting glucose (IFG), Orafti®Synergy1 supplementation significantly reduced fasting insulin and insulin resistance. A meal tolerance test in a subgroup of 13 participants further revealed that the chicory root fiber enhanced early insulin secretion after a meal without changes in total insulin secretion, and increased early GLP-1 secretion in comparison with the control.
Anke Sentko, Vice President Regulatory Affairs and Nutrition Communication at BENEO: "The results of these studies is exciting news for pre-diabetics. We know that chicory root fibers help people eat less, naturally. These new results however, stress the impressive potential of Orafti®Synergy1 as a tool in diabetes prevention strategies -- moving it beyond just the realm of enhancing weight loss. With its mild, sweet taste chicory root fiber can be easily integrated into a person's daily diet."
