I don't know much as I am new on this forum, just joined the beginning of March. I haven't gone through tx yet either, but here goes. My hands and feet swell, so I stay away from salt. Also, I eat meat, but I try to stay away from fried foods. I really don't know the reason other than they're greasy and maybe harder on the liver than other foods. As far as the cooking oil, I think peanut oil, virgin olive oil. You know what? As far as what kind of oil, I don't know.
