Effect of a "Fast Food" Diet on the Urinary Excretion of Maillard Reaction Products

Abstract

The impact of a diet consisting mainly of "fast food" on the urinary excretion of glycation compounds compared to a usual diet was studied. 9 volunteers followed a well defined diet, starting with one day of individual diet of choice followed by four days of "fast food" embedded in two day periods of MRP-free diet. 24 h-urine samples were collected and analysed for contents of free Amadori product and pyrraline. Urinary excretion of the glycation compounds decreased by 70% to a basic level as a consequence of the MRP-free diet. The following "fast food diet" lead to an increase in excretion of both lysine derivatives, giving evidence for no significant differences between the urinary MRP contents after the individual diets and the "fast food diet". In summary, our data confirm, that urinary excretion of glycation compounds is affected by the daily diet. Consumption of a "fast food diet" did not lead to an increased urinary excretion of MRPs compared to the diets usually followed by the participants.
