Study of the urinary and faecal excretion of Nε-carboxymethyllysine in young human volunteers

The dietary habits of the adolescent population with a high intake of snack and fast foods mean that they consume a high rate of which in turn leads to the development of different degenerative disorders. There are few studies available on MRP absorption and metabolism. We investigated the effects of a MRP-high and a MRP-low diet on carboxymethyllysine (CML) intake and excretion in 11–14 years adolescent males. In a 2-period crossover trial, 20 healthy subjects were randomly assigned to two groups. The first group consumed the MRP-low diet for 2 weeks, observed a 40-day washout period, and then consumed the MRP-high diet for 2 weeks. The second group received the diets in the reverse order. Subjects collected urine and faeces on the last 3 days of each dietary period. The consumption of the MRP-high diet led to a higher CML input ( P
