The organoleptic characteristics of fructose and sucrose have no differential influence on their consumption by healthy subjects.
Fructose and sucrose have different organoleptic characteristics. We studied their net impact on the rate of sugar consumption in 8 healthy families. Each family, consisting of the two parents and their 1 to 4 children, received the two sugars in a randomised cross-over blind random design. Each sugar was given for a period of one month preceded by an adaptation period of 15 days. We found no significant difference between the amount of fructose or sucrose consumed (2232 +/- 1361 vs. 2260 +/- 1272 g/family/30 days, respectively). All the subjects consumed only moderate amounts from the two sugars (17.9 +/- 8.5 vs. 18.1 +/- 7.7 for fructose and sucrose, respectively). There were no correlations between either the number or the age of children in a family and the consumed quantities per subject. The palatability of the tested sugars were comparable to a lesser or greater extent: 4 families found fructose similar to their usual sugar (sucrose) while the others found it different. Fructose was well tolerated by all the subjects without any gastro-intestinal disturbances. We concluded that fructose and sucrose were nearly equally accepted and consumed in comparable amounts by normal healthy subjects. Thus, the type of sugar used has no effect on the rate of its consumption. Several factors, independent of flavour, might contribute to the development of sugars preferences.
