I think Iron is a problem if your disease has progressed to the point where you are not processing the iron. At that point you would probably be advised by your doctor about your diet. Eating watermelon and apples should be fine for you if that is not your situation.
My doctor said I can eat everything I like. Particularly fruits and veggies. I don't think it is tx or hep C itself that restricts the diet, it is all other problems that people might have (BP, acids etc)
I think some HCV patients have issues with iron storage, but certainly not all of them. For that reason, it might be a good idea to avoid *supplemental* iron; that is, extra iron in vitamins, etc. I wouldn’t think dietary iron found in foods is an issue, as Spectda posted above.
If there is any doubt an ‘iron studies’ blood test will resolve the question,
I think you should eat natural sources of iron like fruits and veges because you sure don't want to and iron deficient anemia to your symptoms along with the kinds of anemia we get with the tx. I think Bill is right about not taking vitamins with "ADDED" iron because that would put extra strain on your liver. The liver likes to process "natural" stuff... that's what it was made to do in the first place.
