Effects of Polyphenols on Iron Absorption in Iron Overload Disorders.

"After 6 hours of fasting, each patient will eat a complete meal course, containing 40 mg of iron, at two different days (wash-out period: 3 days between each meal).~During each meal, each patient will receive, two capsules containing polyphenols or two placebo capsules (cross-over methodology). The meal in which each patient will receive either polyphenol or placebo will be randomized.~The diet consists of :~* Starter: duck gizzard salad.~* Main course: black pudding and pasta.~* French cheese.~* Fruits: kiwi fruit.~This diet contain approximately 40 mg of iron, with low polyphenol intake. Patients will be asked to eat the whole gizzard and black pudding to ensure the highest iron intake.~At the end of the meal, blood samples will be collected at 0 minute, 30 minutes, 1 hour, 2 hours, 3 hours and 4 hours, to assess serum iron level, in order to measure the area under the curve of iron kinetic."
