Yes! Vitamin C is the most important nutrient from the list of home remedies for kidney infection. It supports your immune system in combating against infection and increases the level of acid at the kidneys which will destroy the bacteria that trigger the development of infection as well.
You can consume 1 – 2 grapefruits, oranges, broccoli, potatoes, peppers, sprouts, tomatoes, strawberries and kiwi... every day. If you are taking supplement of vitamin C, you should ask your doctor for the advice.
I also agree with Ofonorow. Cranberry juice is very helpful in treating kidney infection, just 1 unsweetened glass of cranberry juice every day is enough (if you drink too much, the risk of having kidney stones as this fruit contains oxalate will increase).
