Having thought a bit more about the diet John used to prescribe, I think it varied a bit depending on the severity of the cancer - for Gunner, he wasn't allowed any protein except 2oz of lamb's liver per day (that was for a 62lb dog); no salt in any form (even cucumber's weren't allowed as apparently have some sodium in them); only grains allowed were oats, to be made into biscuits just using water; no mushrooms (but all other veg OK and had to be organic); carrot juice VERY good and had to be given several times daily - as much as he would drink; sprouted wheat and alfalfa also VERY good and given daily. No fat of any kind. Only bottled mineral water to be given to drink and for making the oat biscuits (NO tap water, ever!) - and sodium content to be checked so one very low in sodium to be used (some are quite high).My dog Sal was on the raw liver, too - but I didn't remember a quantity being mentioned. We had organic carrot juice, too.
Obviously this diet is pretty restrictive so you wouldn't keep a dog on this for ever, just for duration of treatment then ease some other things in. To make up for the low protein, Gunner was given a B12 injection every day by John. He also had liquid potassium every day and Vitamin C powder (ascorbic acid) was to be added daily to his food; also given Nicatinamide tablets (a form of Vitamin B3 - this particular form causes the blood vessels to expand so helps circulation - but causes something like a hot flush - which obviously you can't see in a dog but did used to make Gunner pant! I think that effect is lessened if they're given with food) And given pancreatic enzyme capsules several times daily (derived from pigs) - so quite a lot more involved than just the CV247, so hopefully this info. will be given out with the sachets (as I'm sure all these supplements can be obtained quite easily) - obviously the Hungarian vet who worked with John would know all the precise details of this.
I know the diet was based on the Gerson Therapy used to cure cancer in humans - lots of info. on that on the net - Max Gerson's book " A Cancer Therapy: Results of 50 Cases" talks in depth about the diet in one or two chapters and his reasons for it (John lent me his copy at the time to read) but there may be more books out now for anyone who wants to really go in depth into the reasons for it.
Fascinating insights here from Mandy re the souce of the diet idea. I remember from the waiting room that those pets that stuck to John's diet were the ones getting better the quickest - so it's worth working at the diet.
After the cancer emergency was over we added a pasta and yogurt meal into the mix and that was just fine - and she never looked her age - right to the day she died aged 16.
