Diet

Organic food where possible, but that I know that can get expensive
No caffeine (black tea or coffee) but as much green or white tea as you can drink in a day (I have around 3 cups usually)
Lots of water
No milk, I've switched to soy milk, but butter and other dairy is ok
Eggs are ok
No margarine
No alcohol – for now!
Unprocessed wheat (no white bread, pasta or rice, you want the heavy stuff – if it feels like a brick it's probably perfect) You can easily get this kind of bread at the supermarket, eg proper rye bread
Protein (lean meat, fish, tofu etc) x 2 day
As many veggies and fruits as you can eat – try to eat as many different coloured ones as you can (my naturopath said try and eat a rainbow each day) If you have or can get a juicer they are great for getting massive quantities of fruits/veggies in one hit
Whole grains, nuts
Berries
Bananas are very high in potassium (muesli with a tablespoon of LSA powder from the health food store, a chopped banana and sultanas sprinkled on top is a very good breakfast under this regime and my boys are even eating it voluntarily!)
Natural oils (eg olive etc)
Use 'wet' cooking (steaming, poaching) where possible and avoid charcoal
We're only human and everyone needs a sugar fix every now and then. Really dark chocolate (at least 70% cocoa content) actually has some medicinal properties. Look for recipes with cocoa instead of chocolate.

From what I've read, this is basically a low GI diet, but with a few differences, eg all fruit and veggies are great. I stuck to this absolutely religiously for a year during my treatment – I never let myself even consider 'cheating' and I can honestly say it enabled my body to cope - with chemo in particular. It still made me feel totally crap and the nausea was horrendous on the chemo days, but I was pretty ok in between which I put down to my supplements and diet.

The longer I've been off my intensive treatment, and the better I feel in body and mind I find I no longer need some of these supplements - and have definitely lapsed diet wise in a few areas! I do try and maintain a healthy lifestyle though with everything in moderation. In terms of supplements, as a maintenance schedule I take a multivitamin, Omega 3 and spirulina.
