Two years ago I had an ulcerative colitis flare up that just wouldn’t end. I was trying to avoid needing to start a new drug that I was scared of, and I got pretty invested in the idea of alternative treatments. I researched one in particular, the specific carbohydrate diet. For reasons that I won’t take the time to explain as they’re not exactly relevant to this discussion, it recommends treating ulcerative colitis by cutting out all sugars except for glucose. This is why I know how difficult it is to completely avoid sugar. The list of permissible foods is not very long. I’m not sure why your suggested diet includes cutting out meat, but trying to do so in addition to the restrictions outlined by the specific carbohydrate diet seems almost impossible.
I’ve pulled out the book I have on the diet to help argue my case. It is called Breaking the Vicious Cycle by Elaine Gottschall. Gottschall is the woman who developed this diet.
Rice and all other carbohydrates aren’t allowed because all carbohydrates break down into simple sugars in the small intestine.
The allowable proteins listed in the book include: beef, lamb, pork, poultry, fish, eggs, natural cheeses, homemade yogurt, dry curd cottage cheese. So cut out meat from that and I guess there are still a few sources of protein, but it’s very difficult. Almost all commercially available protein shakes are VERY heavy in sugar. For beans, the book says the following are permissible: dried white (navy) beans, lentils, split peas, dried legumes (but only if prepared according to some very specific instructions outlined in the book), lima beans, string beans. Not permitted are garbonzo beans, bean sprouts, soybeans, mungbeans, fava beans. Milk is banned.
The sugar in apples is indeed different from sugar in candybars. But if tumors feed on sugar as you say, and we’re trying to starve the tumor, it doesn’t make a difference if the sugar comes from an apple or a candybar. Glucose is allowed in the SCD, so many fruits are permissible in this diet, but I don’t know whether this is true of the diet you are promoting.
I have to add that following this diet means preparing ALL your own food, since almost all pre-prepared foods have added sugars. I should hope any cancer patient following this diet would have a lot of help from loved ones, as I can’t imagine them having the energy to do all that work themselves.
And don’t discount the nausea associated with some of these illnesses; it can be nearly impossible to force yourself to eat foods you want sometimes, let alone foods complying with this very difficult diet.
I ended up deciding against using the SCD for my ulcerative colitis because it was so much effort for a treatment that isn’t even proven to work. But before making that decision I drove myself almost insane with the pressure of trying to make sure all my foods were “safe” according to this very restrictive diet. Having to be so paranoid can have some very bad effects on one’s quality of life too.
