Fibersol^®-2, resistant maltodextrin (RMD), a soluble source of dietary fibre (DF) is a mixture of oligosaccharides (glucose units DP ≥3) with an average molecular weight of 2,000 Daltons. Resistant maltodextrin was evaluated in three human studies (1, 2 and 3). In Study 1, 20 subjects, in a cross-over design experiment, were fed 300 g rice, with or without 5.7 g (5.2 g TDF) RMD in green tea. During the 120- min postprandial period, insulin and glucose levels were significantly lower in the group consuming RMD, at 15-, 30- and 60- min, compared to the group without RMD. In Study 2, 13 subjects evaluated in a cross-over design experiment, were fed a food-franchise fast meal consisting of a hamburger, French-fries, and a non-calorie carbonated beverage with or without 10 g of RMD (9.0 g TDF). Blood insulin levels were significantly lower at the 30- min post-prandial period, among subjects consuming RMD, compared to subjects not consuming RMD. Blood triacylglyceride levels were significantly reduced among subjects consuming RMD, as measured over a 6- hr period. In Study 3, 12 overweight males with hyperlipidemia were fed 30 g of RMD per day (27.0 g TDF), 10 g per meal, for three months. Although total weight did not significantly decline after three months, 73.7 ± 3.4 kg vs. 73.0 ± 3.3 kg in these individuals, body fat was significantly reduced from 27.7 ± 0.9 to 25.9 ± 1.0%. The area of visceral fat and subcutaneous fat viewed and measured by computed tomography was reduced after three months, and reduced significantly in five subjects, who had initial visceral fat areas above 100 cm², from 139.0 ± 15.7 cm² to 118.2 ± 13.3 cm², an approximate 15% reduction. In summary, the evidence of physiological changes in humans fed RMD in one-time meals and over an extended period continues to support its efficacy as a source of DF for better human health.
