On Dr. Oz's show yesterday, the subject was ovarian cancer. A doctor recommended three foods that actually prevent the cancer. They are - raw onions, Belgian endive and sea bass.
Well, have you ever priced sea bass? I checked with 2 supermarkets and the first one said they don't carry it because it's too expensive. The second one did carry it frozen and the price was - wait for it - $26/pound. Not going to buy it in the forseeable future unless it goes on sale which I very much doubt.
