A safe detox diet?

Options
I've done this once before, a week of detoxing and felt amazing afterward! I haven't been eating clean for the past few weeks and feel like a short detox would do me & my body good!

I don't want to do any of the pills or drinks you buy... just good natural food.

The one I did last time focused on rehydrating your body (which I need to do) and starting with fluids and adding foods each day... it went something like this:

Day 1: Only fluids - (fruit/vegetable juice, vegetable broth, no soda or caffeine)
Day 2: Day 1+ fruits when you are hungry
Day 3: Day 1+ Day 2 + raw vegetables
Day 4: Day 1 + Day 2 + Day 3 + one cooked meal of vegetables and boiled brown rice
Day 5: Day 1 + Day 2 + Day 3 + Day 4 + add beans & lentils (but not with rice b/c it can slow digestion)
Day 6: Day 1 + Day 2 + Day 3 + Day 4 + Day 5 + Live yogurt/sheeps milk and you can replace brown rice with a wholegrain
Day 7: Day 1 + Day 2 + Day 3 + Day 4 + Day 5 + Day 6 +add a fresh fish

I could do this one again... but I'm curious what other detox plans have been followed. Any ideas?
