It makes perfect sense from an internal medicine point of view to fast to heal heart disease, at least from my perspective.
Much of the heart disease stems from an overload of calcium, a heavy lack of magnesium and boron, and inadequate hydration to flush calcified materials out of the arteries. Surrounding damage or foreign particles in the vascular system is a normal part of the immune system, with white blood cells isolating the foreign element by surrounding and calcifying it (mummification of a sort).
The thing about water balance is kind of simple, here's the business end for the heart:
* Magnesium : among many other things, calms a racing heart by allowing the muscle cells and controlling nerves to relax
* Calcium : regulates the speed of the heartbeat in combination with magnesium, and maintains heart muscle strength
* Zinc : Vital in the reproduction of heart muscle tissue, as it's used at the DNA reproduction level while sleeping. It also maintains healthy nerve function in combination with magnesium.
* Boron : Supports health function via hormone regulations and a water-softening effect inside intracellular fluid. It is a mineral that helps one retain water, calcium and magnesium.
* Sodium : An electrolyte, it helps hydrate your cells
* Potassium : A binder and alkiline salt rich in green and yellow vegetables, and is best in a 4:1 ratio with sodium, theoretically
* Iodide/Iodine : A major regulator of hormone production and levels, and a powerful detoxifier, helps eliminate unwanted organisims like viruses and non-helpful bacteria and fungi (yeasts)
The immune-system process is completely independant of oxylate-formation, from what I understand. Oxylates are technically when excess minerals cannot be cleared by the kidneys or they are simply too imbalanced with their compatriots (fx, there is a balance between zinc and iron, between zink and copper, between selenium and iodine, between calcium and magnesium, between potassium and sodium...).
All of those balances effect heart health and strength. So the question boils down to..
What's in the water, and can your body absorb it? (proper vitamin D3 status, study on it. It speeds the absorbtion of all vital minerals from the intestinal track).
I believe it is important to do your study first, plan ahead and eat green and homecooked before an extended fast, and to eliminate outside factors as much as possible. which is... well, almost completely after the book- but the simplest, most important part is keeping a good alkiline salt (body-native salts) balance and being patient. :)
A supervised, well-informed water-fasting plan can save a life. I have a question though.. In cases where there isa massive bodyload of candida/yeasts and toxins to dump, and when the liver spills a lot of bile from squeezing these baddies out of the body tissues, isn't it vital to have anabsorbant in the intestines like calcium bentonite? That should.. I believe, ease the heartburn that sometimes happens? I would not reccommend it to anyone without being prepared with a kilo or so of Epsom Salt
in store to balance the calcium-mangesium ratio properly.
Anyways, down-the-hatch :)
