I've talked to Kay about this before, and I'm hoping she'll chime in here. A friend told me he had seen discussion of the green on potatoes (solanine), in which one of the writers mentioned a toxic substance in green tomatoes as well. I just received a copy in the mail, and it's from the "solutions" section of Organic Gardening, Nov/Dec., '97 issue. OG quotes Dr. Rod Bushway, professor of food science at the U. of Maine, as saying "Green tomatoes contain a glycoalkaloid called tomatine, which disappears as the tomato ripens." (there is also a recommendation that you not trim away the green and eat the rest of the potato, but discard the whole thing to be safe.) Any reactions? Margaret
