You're right about sugar, it's the worst food for everybody but especially for those who have cancer. But we still also have to watch out for carbs and food that has high glycemic index. The bad thing about sugar and carbs is the high glycemic index that they have (not all of them), it rises the blood sugar and the insulin wich is very good food for cancer cells! It's very important that you also know the right food combinations because carbohydrates are not metabolized always in the same way, it depends on what other food you combine them with. With the right combinations you can lower the glycemic index! Women with cancer, especially when in treatment need to have high protein intake and always many veggies, lots of water and carbs with low glycemic index. One trick is to eat whole grain pasta, rice, bread bc the fibers lower the glycemic index. Also protein (meat, fish, chicken) and veggies do that bc of the extra fibers. One of the tricks that she taught me was to have a small meal/snack every 3 hours so I don't get so hungry and eat junk food. Also there are many sweet products with stevia or other sweetener. Anyway you should find a good nutritionist that understands you and can help you. Mine was very helpful, bc she made me weekly diet according to my taste and the family weekly diet too, so it wasn't so hard to follow. I don't want to be a smartass and let me tell you that when I was in the middle of my chemo (I was having 4 medicines weekly, for 5,5 months, it was hard), I couldn't follow the diet. I mostly ate soups, tea, bananas and porridge. Hope I helped you. Can't really tell you about certain products since I live in Greece! Sorry for the long sheet.
