What is it that you are trying to address with diet? The iron overload or something else.

The best thing for hemochromatosis is to get the phlebotomies to keep the iron levels (fe) around 50 -70. Beverages with tannins can help reduce the absorption of iron from your food. So having tea or wine with meals could help. Vitamin C increases the absorption. But you are best served by getting regular phlebotomies.
