If the body has the intelligence to produce a disease, it is capable of reversing the process to return to health once the cause is removed. Disease is a compensation or reaction to a wrong committed. The body holds on to the disease in order to survive in the face of the violation of a natural law which continues to be committed. The longer the body has had to be in a survival mode the longer it will take to return to health. The only limitation to the body's return to health is the limitations we put on the body, both out of ignorance and indifference.
All diseases are curable by the body by adhering to natural healing-principles.
Some people find themselves diseased, change to a natural living lifestyle and do not gain total health, some even die of the disease. The disease process had such a momentum going that not enough time was available for the sick, toxic, inefficient body to utilize the newly introduced nutrients and energies for reversing the disease before the disease killed the body. Remember it is the body's action or utilization of the nutrients for healing, not the nutrients' action on the body. A person may spend years tearing their body down and filling it with toxins, so an immediate healing is impossible. It is doubtful if anyone can become totally healthy within one year no matter how dedicated one is to healthful living and eating.
