What I find most interesting is a certain correlation of “The Gerson Therapy” with a Japanese system of healing called “Macrobiotics”. I have very little knowledge of the the birth of and history of Macrobiotics, but I know their core principal is to achieve a balance between sodium and potassium. They claim the the perfect ration is 7:1 potassium to sodium. Outside that ratio there are health related disturbances across the spectrum of health.
So how does this relate to Gerson Therapy? Gerson Therapy is totally plant based, no animal protein and hardly any plant protein. You can survive about 10 weeks without any protein, by then any store of essential amino acids will be used up. In most western diseases there is too much sodium and too little potassium to balance the ratio. Exactly why I do not know, but when you remove protein from your diet the excess sodium will be flushed from the system. A urine test would show high levels of sodium. And in combination of plants high in potassium the intra and inter cellular fluid ratios are re-balanced.
The ratio of potassium to sodium can go the other way and produce other health problems, and it is conceivable that you could have high sodium to potassium ratios in one part of your body and the opposite situation in some other part. But again the key is to temporarily deplete protein so that the system can equalize. If animal fats are also a player in maintaining this imbalance, I do not know but can only speculate possibly.
While this seems to be the main mode of action, the detox of other undesirables is important as well.
