Fructose absorption

Abstract: Fructose found in modern diets as a constituent of the disaccharide sucrose is absorbed by a well-characterized absorptive system integrating enzymatic hydrolysis of the disaccharide and transfer of the resulting two monosaccharides through the apical membrane of the epithelial cell. The increasing use of high-fructose syrups and crystalline fructose prompted new studies aimed at the determination of the absorptive capacity for free fructose in the human gut. Results indicate that the capacity for fructose abs… Show more

“…Although the conclusions we draw from this study rest on the assumption that fructose and glucose differentially affect glucose and insulin levels, there is a large body of evidence that supports this assumption (for reviews see Riby et al, 1993;Tappy and Le, 2010).…”

“…The glycaemic index value for fructose (16) was half the mean value of four studies, (32AE 2) (Foster-Powell & Brand Miller, 1995), which may be because of a higher than normal prevalence of malabsorption among our subjects. It is well known that fructose is poorly absorbed (Riby et al, 1993). In a series of 103 subjects given 50 g oral fructose in water, 26 (25%) experienced symptoms (Truswell et al, 1988).…”

“…The 13 different test meals consisted of the drink alone; 25, 50 and 100 g carbohydrate portions of white bread; 25, 50 and 100 g glucose (Bio-Health, Dawson Traders Ltd., Toronto, Ontario, Canada); 25, 50 and 100 g sucrose (Redpath Sugars, Division of Redpath Industries Ltd., Toronto, Ontario, Canada); 25 and 50 g fructose (Sweeten Less, Maximum Nutrition Inc., Toronto, Ontario, Canada); and 50 g fructose plus 50 g glucose. Fructose alone was not given at the 100 g dose because it was considered that this dose was likely to cause symptoms of malabsorption (Riby et al, 1993). The tests were grouped into 5 blocks: drink alone, glucose, fructose, sucrose and bread.…”

“…Also, diets rich in free or total fructose (considering its presence in other carbohydrates) can be highly prejudicial, inducing obesity, diabetes, dyslipidemia and insulin resistance [7]. This is of special relevance for people suffering from fructose intolerance, which may be partially prevented with the simultaneous ingestion of glucose [8], being envisaged a glucose/fructose ratio equal or greater than one.…”

“…Among the healthy indexes used in association studies of diet and chronic diseases [9] two are common: the glycemic load (GL), which quantifies the overall glycemic effect of a portion of food [7,[9][10][11][12] and the fructose-intolerance (FI) index, mainly for people suffering from fructose malabsorption [8]. In fact, these indexes can be more useful nutritional concepts than the chemical classification of carbohydrates, since they may allow a better understanding of the relation between physiologic effects of carbohydrate-rich foods and health [10].…”
