Oligofructose health benefit, weight loss by Ray Sahelian, M.D.
Oligofructose is a subgroup of inulin. Inulin and oligofructose are naturally occurring dietary components that are becoming increasingly important as Americans’ desire to boost dietary fiber intake. Inulin also is recognized as a prebiotic ingredient that supports the natural, healthful bacteria in the lower GI tract.
Loss of weight with supplementation
Weight loss during oligofructose supplementation is associated with decreased ghrelin and increased peptide YY in overweight and obese adults1,2,3

Rodent studies show that oligofructose promotes weight loss, stimulates satiety hormone secretion, reduces energy intake, and improves lipid profiles. Our objective was to examine the effects of oligofructose supplementation on body weight and satiety hormone concentrations in overweight and obese adults. This study was a randomized, double-blind, placebo-controlled trial. Forty-eight otherwise healthy adults with a body mass index (in kg/m2) > 25 were randomly assigned to receive 21 g oligofructose per day or a placebo (maltodextrin) for 12 wk. There was a reduction in body weight with oligofructose supplementation. Independent of other lifestyle changes, oligofructose supplementation has the potential to promote weight loss and improve glucose regulation in overweight adults. Suppressed ghrelin and enhanced PYY may contribute in part to the reduction in energy intake.
Cargill has announced that it has expanded the GRAS
(Generally Recognized As Safe) status of its Oliggo-Fibe0 brand of inulin and
oligofructose products through an independent evaluation by a qualified
scientific expert. The expansion gives food and beverage manufacturers the
freedom to add inulin and oligofructose ingredients to an even broader variety
of consumer-friendly food brands. The expanded GRAS status permits the Oliggo-Fiber
inulin and oligofructose line of products for general use in foods at levels
consistent with current good manufacturing practice. Oliggo-Fiber inulin was
previously deemed GRAS by an expert panel of independent and qualified
scientific professionals for use in a list of specified foods, but the “general
food use” approval opens doors for other food formulation opportunities. Oliggo-Fiber
inulin, known as the “invisible fiber,” can be incorporated into almost any food
or beverage without affecting taste or texture. Cargill is an international
provider of food, agricultural and risk management products and services. With
149,000 employees in 63 countries.
