Parts of the body are replaced every twenty-four hours, other parts less often.
Scientists tell us that the whole body is replaced every seven years. Every move you make destroys cells which nature has to replace. Isn't it reasonable then to conclude that if a man should fail to eat enough lime for his body-building, his bones would suffer. If he does not get enough iron his blood will suffer, and so on.
I am definitely convinced that most of the actual physical ailments are caused by a deficiency of the mineral elements in the body.
Phosphorus and potash are necessary to the human welfare. These elements are in the husk of the wheat and the husk is taken off in making flour, and the flour is mostly starch.
The person who lives mostly on white bread will suffer from lack of phosphorus and potash.
Phosphorus also is found in the skin of an apple, so if you peel an apple you do not get the phosphorus.
