wow... kidney infection... ouch, well what ever you do, do not take the anti-biotics.
If you are getting big time reactions, then it might be that you are detoxing very fast. Or perhaps the candida is eating the sugar, because oranges have alot of sugar. My suggestion would is this... go raw. Eat foods that do not cause a reaction in your body. So if apples dont cause a reaction, then eat them. If celery doesnt cause a reaction then eat celery. In the end the idea is to eat fruits and veggies that dont cause reactions, while allowing you to still detox.
I would also limit my meals a day to one or two. One at lunch, and the other around 5 pm. This gives the body about 18-19 hours without food processing... kinda like a mini fast. While making sure to get enough distilled water... hard water could be the cause of your kidney infection. Eat only enough till your hunger is quenched. Then as time goes on and you start to feel better start adding more and more different foods.
But do not go back to cooked foods... they are not healing. Stick to fruit as 80% of the diet and the rest easily digestable veggies. Nuts, beans, and grains all have enzyme inhibbitors and cause problems in the raw food diet. I do not trust them even soaked, or sprouted. I think they should be used much like herbs, only to return the body back to balance... not as food. Keep on following MH, and use what god gave you... to figure out what you need by what god gives us. So if you crave sweets, eat fresh sweet fruit. If you crave salt, then eat sodium fruit like tomatoes. If you crave crunch... get some celery. If you crave carbs like bread... eat avocados and bananas... both are high in fat. Never eat things that are unbalanced... like chocolate. This contains flour, dairy, sugar, and a whole load of stuff all mixed together to make something that is not balanced. This causes problems in the body.
Also start sun gazing, dry brushing, and getting lots of time out doors. These are excellent ways to reconnect with nature. Because that is the root of all disease... disconnecting from God, which is disconnecting from ourselves.
