Effect of a Pomegranate Extract on Cardiovascular Risk Markers in Overweight Healthy Subjects (POMEcardio)
Effect of an Ellagitannin Rich Pomegranate Extract on Cardiovascular Risk Markers in Overweight Healthy Subjects. A Double-blind, Cross-over, Dose-response, Randomized, Placebo-controlled Trial (The POMEcardio Study)
The investigators objective is to carry out a placebo-controlled, dose-response, randomized clinical trial to assess the effects of polyphenols or derived metabolites on cardiovascular disease risk in overweight adult subjects upon the consumption of pomegranate extract.
The investigators hypothesis is that chronic consumption of a ellagitannin-rich source such as pomegranate extract could decrease serum oxidized-LDL as well as other inflammatory markers. The correlation between the effect exerted and the subjects' microbiota (capacity to produce the ellagitannin-derived metabolites urolithins) will indicate a possible role of urolithins on the effects.

Sperimentale: Pomegranate extract
Crossover and dose-response: Both groups A and B will consume pomegranate extract and placebo. Both groups will also consume two doses of pomegranate extract and placebo. Group A will consume 1 daily capsule of pomegranate extract and group B will consume 1 daily capsule of placebo for 3 weeks. After a wash-out period of 3 weeks, group A will consume 1 daily capsule of placebo and group B will consume 1 daily capsule of pomegranate extract for 3 weeks. After a washout period of 3 weeks, group A will consume 4 daily capsules of pomegranate extract for 3 weeks and group B will consume 4 daily capsules of placebo for 3 weeks. After a washout period of 3 weeks, group A will consume 4 daily capsules of placebo for 3 weeks and group B will consume 4 daily capsules of pomegranate for 3 weeks. |
