Ehret was a founder of vitalism in dietetics, and pioneer of Ehretism. He claimed to have discovered that the human body is an "air-gas engine" that is powered exclusively by oxygen and that a diet consisting of fruits, starchlessvegetables and edible green leaves ("herbs"), which he dubbed 'mucusless' foods, is the optimum food for human consumption. Ehret maintained human health was determined by the state of the milieu interior, a term and principle espoused earlier by Louis Pasteur. He attempted to demonstrate that mucusless foods were the key to peak health and produced a treatise entitled The Mucusless Diet Healing System.
In 1887, aged 21, he graduated as a Professor of Design from a college in Baden, and was drafted into the military only to be discharged after 9 months of service, because of heart disease. After studying in Frankfurt, he then taught there at a technical school for 15 years. At 31, he was diagnosed with Bright's disease (inflammation of the kidneys) by Dr Gustav Riedlin, and pronounced incurable by 24 of Europe's most respected doctors. He visited several sanitariums in Europe to learn holistic methods and philosophies including the Sebastian Kneipp sanitarium.
In 1899, he traveled to Berlin to study vegetarianism, and where he visited 20 vegetarian restaurants, and the Lebensreform co-operative at 'Eden', a vegetarian fruit colony in Oranienburg. He took a course at a university of medicine, physiology and chemistry, and explored natural healing, and later, courses in naturopathy, physical culture, anti-medicine, magnetic healing, mental healing, Christian Science and reform movements. Still without health, he went to Nice, in France, where he adopted a fruit and milk diet, with mixed results, as he was still unsure about fasting which he had heard about but was unfamiliar with.
After returning to Germany, he reverted to "good eating". The next winter, he took a trip to Algiers in northern Africa with a French bicyclist, called Peter  where he experimented with fasting and a fruit diet. In a desperate attempt to end his health problems, Ehret decided to stop eating, and was surprised to find that he did not starve, but gained in strength and vitality. Due to his new lifestyle, Ehret claimed to have cured himself of his diseases and to be able to perform feats of physiological strength, including a 1000 mile bicycle trip from Algiers to Tunis which he undertook with the trained athlete in under 14 days. Returning to Germany, his sister discouraged him from continuing with fasting. In 1909, Ehret wrote his article denouncing the "Metabolic Theory".
On a separate journey through southern France to northern Italy where he walked continuously for 56 hours, he eventually reached the island of Capri (which Anita Bauer, Ehret's stated secretary, later claimed Ehret regarded as "the isle of the blessed"), with a follower born in 1881 called "Mr B." which some Ehretists believe was Paul Bragg. They then took a boat to Egypt, traveling on to Palestine, Turkey, Rumania, Hungary and Austria, to practice his system. He also allegedly travelled to Persia and India.
Arrival in America
On 27 June 1914, just before World War I, Ehret departed from Bremen for the United States to see the Panama Exposition and sample the fruits of the continent. On 6 July 1914, he disembarked from the transatlantic George Washington on Ellis Island. He then travelled to California, which was of special interest to him, since it was undergoing a horticultural renaissance due to botanists like Luther Burbank, who later paid tribute to Ehret. At the time, the University of California, owned the world's largest collection of rare fruits. The war prevented him returning to Germany so he settled in Mount Washington, where he prepared his manuscripts and diplomas in his cultivated eating gardens.
Benedict Lust distributed the books of Ehret, Kneipp, Kuhne, Just, and Engelhardt in the United States including "Kranke Menschen" which was a best-seller. Ehret worked at Lust's Yungborn Sanitarium for 5 years. Dr. Carl Schultz, a pioneer of naturopathy in California, owned two sanatoriums and teaching institutes. Ehret continued the trend by opening a sanatarium in Alhambra, California, before embarking on a lecture tour. His course on The Mucusless Diet Healing System, became a book of 25 lessons for his students, and later, his most important book. Ehret also developed and marketed the Innerclean Herbal Laxative.
Just two weeks after he completed The Mucusless Diet Healing System, on October 9, 1922, he finished a series of four lectures on Health Thru Fasting and the grape cure, at the Assembly Room of the Angeles Hotel on 5th and Spring Street, where "at least a hundred persons were unable to secure seats". After leaving the building, between 11:00 pm and 11:30 pm, Ehret, aged 56, fell, sustaining a fatal blow to his skull. According to Ehret's business partner and publisher, Fred S. Hirsch D.N.S., he was walking briskly on a wet, oil-soaked street during foggy conditions when he slipped on the curb and fell backward onto his head. Hirsch did not actually witness the fall but found Ehret lying on the street.
Some Ehretists have doubts about the official cause of Ehret's death, including his 1920s German publisher Carl Kuhn who questioned whether Ehret's fall was an accident. Ehret's powerful healing successes along with his influential and radical new lifestyle challenged the medical and agricultural industries, and his writings on religion and family were regarded as contentious. In the decades following Ehret's death, Fred Hirsch had many legal battles with the medical authorities, over the word 'mucus', and the Innerclean laxative.
In "What Really Happened To Arnold Ehret?", Sylvia Saltman recorded October 21, 1927 as the date of Ehret's death. Saltman claimed Hirsch's wife Lucile, had recounted to her that a mystery lady, possibly Anita Bauer, the stated author of the biography about Ehret called The Story Of My Life, accompanied Ehret and Hirsch, that evening. Saltman concluded that Ehret had slipped in his new shoes on spilled car-oil in the street on the foggy night. In slight contrast, Benedict Lust, who was Ehret's American publisher prior to Fred Hirsch, maintained that Ehret was "hastily making his way to the railroad station to board the train for his home in the Los Angeles suburbs." and wearing a pair of new dress shoes which caused him to slip as a result of his unfamiliarity with the footwear.
Another theory was that Ehret was in fact with Los Angeles medical doctor John Dequer that night but suffered heart problems due to coffee drinking. However, Ehret denounced coffee, as well as alcohol and tobacco, as "poisons" in his writings, even though in his visit to Egypt, he noted people who smoked and drank coffee heavily, yet ate a light vegetarian diet, were not suffering the illnesses of western Europeans.
The day after, Hirsch ordered a medical report, conducted by the Los Angeles County Coroner's office, which confirmed a basal fracture of the skull as the cause of death, and Ehret was cremated at Forest Lawn Cemetery, Glendale, Los Angeles, his ashes preserved in a bronze acorn on Coleus Terrace. The death certificate was archived in the Hall of Records at the Los Angeles County Recorder's Office.
For 65 years, Fred and Lucille Hirsch published Ehret's literature and the torch symbol found on Ehret's books became the logo of the Ehret Health Club. In 1979, the Ehret Literature Publishing Company Inc, in New York, inherited Ehret's publications and archive of unpublished German manuscripts on nature cure, natural diet, physiology, history, philosophy, religion, metaphysics, spirituality and Nietzsche including The Ascona Lectures and About The Healthy Human. A 5 stanza poem entitled "Ehretism", also in the archive, has appeared at the Breathairean Ensemble website.  A photograph of Fred Hirsch with Albert Einstein also appears in the archive.
In 2002, Dr Ludwig Max Fischer, Professor of German at Willamette University in Salem, Oregon, and a follower of Ehret's teachings, translated Ehret's Kranke Menschen from old German into English. The new book featured new photos of Ehret, Ehret's birth certificate, his death certificate and the advertisement in the Los Angeles Times of 8 October, advertising the final 'free lecture'.
Views on disease
Ehret claimed that pus- and mucus-forming foods were the cause of human disease, "schleimlose" (slime-free) foods were the key to human health and "fasting (simply eating less) is Nature's omnipotent method of cleansing the body from the effects of wrong and too much eating." The term mucus, a glyco-protein acid, derives from the Greek "myxa". In 1812, William Cullen referred to mucus as 'butyraceous matter' and in 1877, Gustav Schlickeysen referred to a mucus layer beneath the human skin in Obst Und Brod. It was later termed 'mucin' by Dr. Teofilo De La Torre in the 1950s, 'mucous' by Morris Krok in the 1960s, 'impacted fecal matter' by Norman Walker in the 1970s  'mucoid matter' by Robert Gray in the 1980s, and 'mucoid plaque' in the 1990s. In the 2000s, Daniel Reid re-introduced the term 'mucus'. Gray further noted the distinction between healthy and unhealthy mucus, and how certain substances left an internal residue which the body suspended in mucus, in contrast with a fruitarian diet.
Within 14 months, Ehret fasted for 126 days without food. He had completed a fast of 21 days, one of 24 days, one of 32 days, and one of 49 days which he commenced on 26 June 1909 at Kastan's Panoptikum (waxworks), in Cologne under the watch of a notary from the Royal Court. In 1909, he fasted, in total, for 105 days. In 1910, he wrote an article for a German vegetarian magazine about his 49-day fasting experience, which gained the public's interest, and which later appeared in his book Lebensfragen (Life Questions).
Having denounced the nitrogenous-albumin metabolic theory in 1909, Ehret learned of a contemporary, Thomas Powell M.D., in 1912, who concurred with his belief that "grape sugar" (simple sugars in fruits and vegetables) was the optimum fuel source, body building material and agent of vitality, for humans, not protein rich foods. Powell had set out his beliefs in the book "Fundamentals and Requirements of Health and Disease", published in 1909. Ehret claimed alkaline foods, which were also mucusless, formed the natural diet of humans. His findings about food values and pH values, were supported by chemist, Julius Hensel, and Swedish chemist, Ragnar Berg. In 1911-1912, Ehret conducted seminars and conferences in Germany, Switzerland and Monaco, about his discoveries, gaining support from Dr. Katz, the owner of a natural healing center in Stuttgart who wrote about Ehret in Lebeskunst magazine in 1911.
Along with his sister, Ehret was brought up as a Roman Catholic. He believed in God, but took issue with the Church because of its dietary requirements in a letter to the Pope, and subsequently quit the Church, though his faith in God remained. After his death, the Archdiocese of Los Angeles, who was aware of his writings on Jesus, wrote to Fred Hirsch to confirm he would ban Catholics from reading Ehret's religious writings, if published. Prior to this, Ehret was popular with the bishop and the Catholic fraternity, due to the strong tradition of fasting within the Church.
According to Hirsch, in Ehret's unpublished book about Jesus, and letter to the Pope, Ehret described his belief that Jesus had not died on the cross, but had been taken down alive and revived with herbs and ointments. Ehret believed his proposed diet led to absolute communion with God.
The Mucusless Diet Healing System (MDHS) consists of various kinds of raw and cooked fruits, starchless vegetables and edible green leaves, to re-alkalize the body and build new blood. It uses a combination of long and short-term rational fasts, menus that progressively change to non-mucus-forming foods, and colonic irrigation.
Ehret believed that by using his transition diet system, any serious practitioner could move away from mucus-forming foods to non-mucus forming foods, especially using mineral-rich organic produce. However, he recommended caution and rationality during the transition program, since too rapid detoxification could lead to various illness symptoms depending on the individual's constitutional weaknesses and approach to the system. When toxemia or mucus entered the blood circulation system too quickly or where food combining was not followed, elimination of toxins and assimilation of nutrients, could be hindered. This was later affirmed by Jethro Kloss and Henry Bieler.
Ehret asserted that the body was an air-gas engine, not dependent on food for energy, and that the body was not designed to utilize mucus-forming foods, offering the equation Vitality = Power − Obstruction (V = P − O) to demonstrate this. Ehret also claimed the lungs were the pump in the body while the heart acted as a valve, with the blood controlling the heart - a concept also mentioned by Dr M. J. Rodermund in 1904. Ehret further believed that white blood cells were the result of ingesting mucus-forming foods.
Ehret maintained new tissue was built primarily from simple sugars in fruits, not metabolised from protein and fat-rich foods. Ehret only favored nuts and seeds during transition to the ideal fruit diet, and even then, only "sparingly", condemning high-protein and fat-rich foods, as "unnatural"; further writing that "no animals eat fats" and "all fats are acid forming,even those of vegetable origin, and are not used by the body" Later editions of his Mucusless Diet Healing System published by Fred S. Hirsch, claimed nuts were "mucus-free". Ehret specifically renounced meat, eggs, milk, fats, cereals, legumes, potatoes and rice, whilst recognizing the transitional value in some of these. Ehret, citing Ragnar Berg, noted that fats and proteins were acid-forming and were to be consumed in moderation, as did Ehret's contemporary Otto Carque.
In 2009, Harvard Medical Doctor, David L. Duffy wrote: "A study in the Journal Of Clinical Endocrinology and Metabolism finds that 'A diet that is high in protein and cereal grains is metabolized in a way that produces residue with an acidic pH. This may increase calcium excretion and weaken bones.' I believe it may also inhibit the release of oxygen from the red blood cells to the body."
Ehret believed a fruitarian diet was the ideal diet, however he was unable to demonstrate the long term viability of this diet, due to his sudden death.
In his writings, Herbert Shelton claimed Ehret had admitted in a public lecture that he had little experience or understanding of fasting. Shelton also claimed Ehret made no distinction between mucus and pus, even though Ehret explained blood vessels can be obstructed with mucus-forming foods, which decompose, ferment and degenerate into pus.
Johnny Lovewisdom claimed that Shelton claimed that Ehret enjoyed coffee, wine and cigarettes, and that coffee drinking caused his demise. In "Lebensfragen", Ehret described his use of coffee, alcohol and cigars, prior to his detoxification path, and use of meat, during his early dietary experiments. Lovewisdom also maintained that Ehret promoted grains, nuts and seeds as ideal foods, even though Ehret described them as part of "The Destructive Diet Of Civilization".
In his writings, Ehret differentiated his method from natural hygiene (orthopathy), naturopathy, rawfoodism,vegetarianism, the mineral supplement movement, and other systems, since his knowledge of disease and other concepts contrasted with theirs. Natural hygienists have criticized Ehret for renouncing nuts and seeds as ideal foods, whilst advocating other foods in transition such as sauerkraut. Rawfoodists have criticized Ehret's use of cooked foods, which are applied selectively, in his transition program.
Another common criticism is that a diet low in protein and carbohydrates, would lead to a drop in blood sugar, causing decreased insulin sensitivity, leading to a state of excitability.
Mucusless diets were critiqued in the book "Diet and Die" by Carl Mamberg in 1935.
Ehret was criticized by Herbert Shelton who did not distinguish between natural and unnatural mucus, unlike Robert Gray. Shelton however recognized that cereals and pulses caused an "acid ash".
Ehret believed that microbialpathogens thrive by the ingestion of certain foods, an idea which is not universally accepted.
Unlike medical practitioners today, who believe white blood cells are important components of the immune system, Ehret believed that white blood cells are caused by consuming mucus-forming foods, and as waste materials, poison the blood.
Potential symptoms associated with detoxification and fasting may include: nausea, rapid weight loss, decreased motor control, vitamin deficiency, mineral deficiency, tooth loss, hair loss, bone loss, muscle loss, organ damage, hyper-ventilation, mental imbalance, pH imbalance, bulimia, hunger, cravings, obsessions and isolation.
Ehret encouraged those new to detoxification and fasting to consult with experts who understood fasting and his system.,
Some Ehretists believe Fred Hirsch embellished the 1954 edition of Ehret's Mucusless Diet book, and later editions have been modified. Other published versions of Ehret's books may also have been updated.
Earlier Spanish editions of Ehret's books contained various translation errors such as using the word legumes instead of vegetables.
The autobiography "The Story Of My Life (as told to Anita Bauer)" is regarded by some Ehretists as fictional.
References to Innerclean, the herbal laxative product marketed by Ehret in the United States, were later removed from Ehret's writings due to government objections to using books in product promotion.
Ehret's early 20th-century views on religion, the Church, Catholicism, homosexuality, motherhood, eugenics, modern science, conventional medicine, alternative medicine, the agriculture industry and the pharmaceutical complex, invited criticism from those factions, which Ehret rebuffed in his books and articles.
In 1992, Octavi Piulats, a professor of philosophy at the University of Barcelona, and doctor of philosophy at the Goethe University Frankfurt, documented Ehret's critique of conventional physiology and naturalism, and how ancient Egyptian medicine, considered mucus, along with a series of astral and demonic influences, as the source of the disease, in Ehret: O La Pasion Por El Naturismo. In 1994, German magazine Stern published a review of a best-selling book by Helmut Wandmaker, who had been inspired by Ehret. In 1995, Pablo Cazau, a psychology Professor at Favaloro University, Buenos Aires, wrote about Ehret and Lezaeta, in the article El Naturismo: Una comparación con la cura psicoanalítica. In 1998, Gordon Kennedy documented Ehret in his book Children Of The Sun.

Eventually the current system of capitalism would be rendered useless and the Earth's people would return back to the mythical 'Garden of Eden', one of the universal paradise myths shared by many divergent cultures." http://breathairmusic.com/physiological/faq.html Breathairian Ensemble Website - Faq, An Introduction to the Mucusless Diet Healing System by Professor Spira
^Still Ehret After All These Years, Gordon Kennedy, Just Eat An Apple, 2000s: "Hirsch also explained that the authorities were also upset by Ehret's essays on sex and motherhood, something they felt prudish post-Victorian America was not prepared to hear, much less accept."
^"They said that because of his crazy ways, he died from one dire deficiency or another; or that he was in an auto accident and his body just couldn't repair itself because calcium was absent from his bones! Fred Hirsch was with him the night he died... October 21st, 1927; a "pea soup" foggy Los Angeles night, so thick you couldn't see beyond the end of your arm. The Professor had just finished the last of a series of four free lectures on "Health Through Fasting", his Grape Cure, overcoming all the body's ailments through the pure and the natural and eschewing all animal and dairy products, astounding the Medical Doctors and helping people from all walks of life... in the Assembly Room of the Angelus Hotel at Fifth and Spring Streets, when a woman approached and once more pressed him into "having a glass of orange juice" at a nearby restaurant to discuss some nonsensical possible reduction of her cost for a forthcoming Course if she brought in "two or three others".", "What Really Happened to Arnold Ehret?", Sylvia Saltman, Vegetarian World Magazine (USA, 1977)

^"Ehret, always a gentle, compassionate man, would hear her out and possibly grant her wish; Fred felt it was unfair to the others who had paid in full (a handful of lectures cost $100 - a stiff rate for the mid-twenties). The free lectures filled the hall every evening and the enrollment response was excellent! Fred was saying no, nix, let's go home, Professor - as he pulled his collar up against the chill eleven o'clock night, but Prof. Ehret agreed and the search for an open restaurant started. The lady, butterfly-like was darting in and out of doorways up ahead. She's now calling from what seemed way across Olive Street. "This way, Professor, hurry, he'll stay open for us! Come on!" Autos around that time "leaked" a lot of oil, and they were presently on a driveway leading into the White Garage on Olive Street - on wet, slippery oil-soaked pavement, shuffling carefully, walking slowly." "What Really Happened to Arnold Ehret?", Sylvia Saltman, Vegetarian World Magazine (USA, 1977)
^"Fred is slightly ahead and turns to take the elbow of Prof. Ehret, the man who saved his life some five years before...... and so they were out in this fogbound night. Fred turns to reach for Ehret's elbow and doesn't see him. He looks down, the Professor is lying on his back by the curb. They had found a driveway through the thick atmosphere, but he was wearing brand new shoes and his foot slipped on some spilled car-oil and down he went without a sound, the base of his head striking the point where the curb met the driveway. The lady was summoned from across the way to call for help. Fred dropped by his side to give first aid. In those days ambulances had only the driver abroad and no life-saving equipment. But it came quickly from nearby Police Dept. Emergency Hospital located at 3rd and Hill. The doctor waiting to receive them took one quick look and said, "This man is dead.....". Fearing ridicule from "non-believers" and to clear all mystery surrounding the unfortunate death of his beloved friend and mentor, a grieving Mr. Hirsch ordered an autopsy, the results of which are available for scrutiny to this day at the L.A. County Hall of Records. Ehret officially died of a basal fracture of the skull." "What Really Happened to Arnold Ehret?", Sylvia Saltman, Vegetarian World Magazine (USA, 1977)
^"Upon leaving the lecture hall, Professor Ehret was hastily making his way to the railroad station to board the train for his home in the Los Angeles suburbs. He was wearing a pair of new shoes for the first time. The street was poorly lighted. In stepping off the curb, he lost his balance, falling backward and striking his head on the stone curbing. A few minutes after the fall he breathed his last, never regaining consciousness. The autopsy revealed a basal fracture (fracture at the base of the brain) of the skull."

^Eternal Youth Life Journal 1947-1985, Johnny Lovewisdom, International University of the Natural Vitalogical Sciences, "Professor Arnold Ehret preached a mucusless diet while ever a great coffee drinker and chain smoker, living only 56 years. He was accompanied by a close friend, John De Quer M.D., after having his usual 6 cups of coffee when he collapsed walking in the street, dying of apoplexy or heart disease, and not by an accident as his publishers claim. Dr Herbert Shelton thought it was due to coffee, wine and tobacco he freely used, beside a lack of protein. His Mucusless Diet Healing System advocates the use of walnuts, pecans, whole wheat toast, Swedish Rye Krisp, Zweiback toast and Cottage cheese".
^"In Egypt, we saw a race of people of extraordinary strength and endurance, living on scanty vegetarian diet mostly, but with two supposedly bad habits - cigarette smoking and drinking strong coffee; yet we saw not a single nervous or toxemic person.

^"Excessive consumption of mucoid forming foods and inadequate levels of intestinal lactobacteria are the principal causes of a toxic colon. The fewer mucoid forming foods you eat, the better the health you will be able to attain. Superb health can never be attained as long as a highly mucoid forming diet is being eaten. Dairy products whether, milk, butter, cheese, cottage cheese, cream, yoghurt, kefir, ghee, and whey, along with flesh products – meat, fish, fowl and eggs, are the most mucoid forming of all foods. Soy beans are the most mucoid forming of all plant foods. Vegetarians who include soy products in their diet are paying pricely homage to the utterly false and highly injurious idea that their bodies cannot do without animal products. Vegetables and fruits are virtually free of all mucoid forming activity. They are Nature's purest foods."

^"Due to our poor eating and drinking habits, stress, pollution, intake of drugs, inappropriate medications and smoking etc, over time the colon may become impacted with a great deal of uneliminated matter which actually hardens and adheres to its walls. This is sometimes referred to as mucoid plaque and quite probably it affects every single person eating a standard Western diet.", Susie Miller & Karen Knowler, Feel-Good Food: A Guide To Intuitive Eating, The Women's Press, 2000, ISBN 0-7043-4546-3, page 34
^"In order to protect itself from the chronic toxic irritation caused by eating meat, fish, dairy, and cereal products, the colon secretes large quantities of mucus to entrap toxic particles before they damage the colon's sensitive lining. When this occurs at every meal, every day, ever week, throughout the year, as is common in Western diets, the colon ends up secreting a constant stream of mucus, which accumulates and gets impacted in the folds of the colon. This results in a narrowing of the passage through the colon and a constant seeping of toxins into the bloodstream by osmosis. When the impacting of toxic mucus in the colon reaches a critical pressure, it causes a pocket to balloon outward through the colon lining, causing a condition called diverticulosis. Colitis and cancer are the next stages of colon deterioration caused by these conditions." Daniel Reid, The Tao Of Health, Sex & Longevity, Simon and Schuster, page 60
^"Mucus is a normal body secretion. All mucous membranes continually secret mucus as a means of keeping the surfaces moist and lubricated. Ingesting any food, or even water, will give rise to an increased level at the back of the mouth of a healthy lubricating type of mucus. These facts are often presented as disproving the validity of the mucus theory. Yet it is easy to distinguish healthy mucus from mucus formed as a reaction to toxicity. Healthy mucus is clear and slippery. Unhealthy mucus is cloudy, thick and sticky and this is the type of mucus produced by mucus forming foods.", Robert Gray, The Colon Health Handbook, Emerald Publishing, 1991, page 30
^"Without a sufficient thyroid output, the metabolism slows down. Food is incompletely burned, and the result is like smoke or soot as compared to a clean-burning flame. This internal smoke or soot is handled in the same way smoke or soot from the outside is handled. The body generates mucoid material to hold the undesired substances in suspension.", Robert Gray, The Colon Health Handbook, Emerald Publishing, page 36

He achieved this by following his own Mucusless Diet Healing System, i.e. a Herbivore/Vegan diet using foods that remove the undigested animal residues he calls "mucus" that gives the white blood cells their characteristic white color from their phagocytosis of Animal/Dietary Cholestrol in their "house cleaning" sanitary body maintenance duties."

Neither are the number of calories ("heat units" by calorimeter tests), reasonable basis for selecting a proper diet. My over forty years of observation, experiences and research have proven conclusively to me that fruits and vegetables have all the tissue salts needed, and that the presence of actually well known ingredients in sufficient quantity are the energy and life supporting ingredients which make them the superior of all other foods, when the debris (mucus) from the "mucus-rich" foods is eliminated.", Professor.

Wei, Inner Traditions / Bear & Company, 2009, The Mucusless Diet, page 186, "Through the alkaline diet, you can create a mucus-free environment internally in the body. This is what we are trying to achieve. In other words, the less we build up mucus, which inflames the body, the more the body is going to function properly. If you look and feel your body, when you eat a lot of the animal products your body just swells up because the inflammation is taking place within the body. In other words, the blood vessels get coated with cholestrol, which increases the size or the tightness of the body to neutralize the acid that is flowing through the blood."
