Healthy Clinical Trial - Intake-dependent Effect of Cocoa Flavanol

Status Completed

Clinical Trial Summary

A randomized, double-masked and cross-over dietary intervention study in healthy young adult males to evaluate the concentration of F-derived metabolites in plasma and urine after single acute intakes of F-containing drinks on four different test days.

Clinical Trial Description

Flavanols (F) are plant-derived compounds commonly present in the human diet. Examples of F-containing foods and beverages are apples, chocolate, tea, wine, berries, pomegranate and nuts. The consumption of F-containing foods and beverages has been associated with improvements in cardiovascular health. In this context, there exists a great interest in describing the absorption, metabolism and excretion of F in humans, as it is thought that F-derived metabolites present in circulation are the mediators of F-beneficial effects in humans. Recently, we described a series of F-derived metabolites in circulation that are present after the consumption of a single acute intake amount of F in humans. A key question, however, is if the metabolites we observed after a single acute feeding are the same as those that occur in individuals who consume F-rich diets on a regular basis. Studies investigating the metabolism of numerous other xenobiotics have shown that the profile of metabolites can greatly vary over time, as well as with the amount of xenobiotic ingested. In this context, and considering that i) the amount of F-consumed from diet greatly varies among individuals, ii) recent epidemiology studies indicate that the vascular protective effects of F diets primarily occur when daily intake of F are relatively high; and iii) there is evidence of an intake amount-dependency on the vascular effects of F in dietary intervention studies; we submit it is important to assess whether or not there are F intake amount-dependent effects on the levels and profile of F-derived metabolites in humans. This study will provide new information concerning the F-derived metabolites that may be responsible for mediating F-beneficial effects in humans. We suggest the information that will be obtained from the outlined work will be particularly timely given ongoing discussion concerning the possible generation of dietary recommendations for F-rich foods. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
