The Mucusless Diet Healing System was written by Arnold Ehret, who at the age of 31 was pronounced incurable of Brights disease.

His major symptoms were mucus and albumin in the urine with kidney pain. Thus he concluded that the best diet for healing should be free from both mucus and albumin and he later went on to study vegetarianism, naturopathy, medicine, and physiology.

He tried various dietary approaches with limited success until he embarked on short fasts while on a fruit diet in Northern Africa, and began gradually to experience a major increase in vitality.

He then undertook longer fasts in conjunction with what he termed a mucusless diet and was able to completely cure himself. Following this he began lecturing and writing about his discoveries.

Mucusless Diet Healing System Basics
Ehrets basic philosophy was that every disease is related to a mucus-clogged system that is the result of the accumulation of undigested and unnatural food substances, commencing in childhood. He believed that vitality depends on removing these obstructions.

Ehret stated that there is only one cause of disease which is overeating and eating the wrong kind of food. He thought that fruit was the perfect food and along with some green leafy vegetables was all that was required in order to attain optimal health.

Ehret devised a mucus-free transition diet for dieters who would like to follow his approach in order to reagin their health and vitality, but find the strict diet too limiting, he actually warns dieters against sudden dietary changes because this can lead to an excessive release of toxins that the body will not be able to eliminate effectively. He recommended two meals daily that should be based primarily on fresh fruit and vegetables, cooked or raw as well as small amounts of raw nuts.

Ehret was convinced that fasting is the key to attaining optimal health and recommended starting his program with a two or three day fast. He also advocated undertaking longer fasts of up to forty days once the dieter has gone through the transition diet. He believed that the first meal of the day should be delayed as much as possible because this extends the short daily overnight fast.
