She told me that I must replace certain key body minerals like potassium with organic sources. Also, you can get supplements at the healthfood store. Take Calcium citrate, the most assimilable form. Later when you're well, get calcium paired with magnesium. Right now, as kidneys are still weak, magnesium is not good for you.
Liquid potassium is better than capsules or tablets.
Use 'Mineral broth' products like Dr. Bronner's or Dr. Jensen's amino broths. They are like soy sauce, a source of salt for your cooking, but full of minerals. And avoid anything acid. Pepsis, cokes, Sodas, full of citric acid, pickles, and all canned or pasteurized tomato products, which lets out Italian foods. Also avoid pasteurized cylinders of citrus juices.
