Re: A few words about Baking Soda
Per Gerson sodium uptake should be greatly minimized for those with cancer. He noticed that it contributes to the inflammation ring around cancer which helps cancer to spread. Sodium bicirbonate is apparently a quick fix of an overacidity problem, and it makes sense more or less just from knowing that our body uses the bicarbonate buffer system. Here's an encyclopedia extract explaining how that works:
***************************************
bicarbonate buffer (first line of defense) which is present in all body fluids is a mixture of carbonic acid H2CO3 and bicarbonate ion (HC03). When a strong acid is added to the bicarbonate ion it combines with it and forms a very weak form of acid - carbonic acid. So basically it's a change from strong acid to the weak. It works the opposite way too. When a strong base is added to the mixture it'll combine with carbonic acid producing water and neutral bicarbonate salt
****************************************
If anything Potassium Bicarbonate would seem a more reasonable choice to me. And I think I've seen someone talking about it. It's also used with vitamin C. Once again it's a quick fix for overacidity problem, there is no way around doing the whole thing of fixing your immune system and the whole body.
