What should my daily diet include to help me combat kidney cancer.?

Read the excellent books: Beating Cancer With Nutrition by Pat Quillen, and How to Prevent and Treat Cancer with Natural Medicine by Mike Murray. Both are full of the kind of info you are looking for, and much more.
Good luck and God bless!

Go to Alibris.com for copies if you can't find one locally.

do you have kidney cancer? just drink a lot of water, just plain water to keep your kidneys flushed of toxins.

antioxidants like vit E ,C

Lots of vegetables, and go for lower protein, the kidneys do better on a vegetarian type diet as excess protein must be filtered by them. You also do not want to go into a kertosis type condition as this is also very hard on the kidneys.
Also avoid alcohol, coffee, soda, and orange juice, all very hard on the kidneys,
drink cranberry juice and water and herbal tea or milk
I had problems with my kidneys when I was 20 and the problems went away about a year after I became vegetarian at 21 or 22 and did not return.

I think I not understand? Is this a now thing or you saying as a preventative???
Eat good well balanced diets. Real food just moderate proportions. Drink Fruit and Vegetable Juices.
Remember; A happy Heart is a Healthy Heart.
This holds true in ALL health. Our own attitude does affect our heath. All I know to say. IF, you already have the Cancer write I try to explain the best cure. Works for some, not for others. But, you not hear it from the Amer. Can Society. They too busy making money!

to my knowledge, you should drink 1,5 l of horse-tail tea daily (one tea spoon of plant infused in 1l of hot water) during the day; take small sips; it is very effective (both i and my mother are using it)
