Yes different people has different perception of good diet.

But from my research and reading from those who are cured, theres a general rule to follow and that is they avoid sugar, flour, condiments, aritificial flavourings and other toxic food.

You can follow a cooked or raw diet, although raw will let you see results faster.
But the key thing is help the body to detox by avoiding toxic food during that 2-3 mths period and also provide the right nutrition.
