Fruitarianism may be adopted for different reasons, including ethical, religious, political, medical, environmental, cultural, aesthetic, economic, and health reasons. There are many varieties of the diet. Some people whose diet consists of 75% or more fruit consider themselves fruitarians.
Some fruitarians will eat only what falls (or would fall) naturally from a plant: that is, foods that can be harvested without killing or harming the plant. These foods consist primarily of culinary fruits, nuts, and seeds. According to author Adam Gollner, some fruitarians eat only fallen fruit.[unreliable source?] Some do not eat grains, believing it is unnatural to do so, and some fruitarians feel that it is improper for humans to eat seeds as they contain future plants, or nuts and seeds, or any foods besides juicy fruits. Others believe they should eat only plants that spread seeds when the plant is eaten. Others eat seeds and some cooked foods. Some fruitarians use the botanical definitions of fruits and consume pulses, such as beans, peas, or other legumes. Other fruitarians' diets include raw fruits, dried fruits, nuts, honey and olive oil, or fruits, nuts, beans and chocolate.
Fruitarianism is also referred to by some as the 80-10-10 diet. This particular form of fruitarianism was created by Dr. Douglas Graham, an unlicensed chiropractor and former athlete. This diet was originally developed through his work with athletes, as a way to boost performance through use of high energy foods. In the 80-10-10 diet, daily calories are broken up so that 80% of calories comes from complex carbohydrates, 10% come from fat, and 10% from lean protein. Of the 80% that is complex carbohydrates, at least 75% of this should come from fruits. Graham claims that it is possible to thrive on a diet of fresh fruit and vegetables, with the occasional supplements of nuts and seeds, because fruits and vegetables naturally contain small amounts of fat and protein. The promise is that by following a 80-10-10 diet, the experience of a person’s body will be transformed, and allow them to thrive in new ways. The strong belief of this diet’s capability to transform the body is shared among many fruitarians. These beliefs lend to tremendous spiritual like feelings leading many to adopt fruitarianism not just as a diet, but as a lifestyle.
Some fruitarians of the Judeo-Christian faiths believe, based on Genesis 1:29, that fruitarianism was the original diet of humankind in the form of Adam and Eve. They believe that a return to an Eden-like paradise will require simple living and a holistic approach to health and diet. Some fruitarians wish, like Jains, to avoid killing anything, including plants, and refer to ahimsa fruitarianism. Some fruitarians say that eating some types of fruit does the parent plant a favor and that fleshy fruit has evolved to be eaten by animals, to achieve seed dispersal. For some fruitarians, the motivation comes from a fixation on a utopian past, their hope being to return to a past that predates an agrarian society, to when humans were simply gatherers. Another common motivation is the desire to eliminate toxicity within the body. For others, the appeal of a fruitarian diet comes from the challenge that the restrictive nature of this diet provides.
Fruitarians boast many benefits to following this strict diet, the main one being the simplicity of the diet itself as it requires minimal meal preparation. As those meals each contain large quantities of fruit, another result of this diet is the stomach stretching to be able to accommodate the large volume of watery, fibrous fruit. Benefits to the body include the improved quality of excrement no body odor, decrease in skin oiliness, significant drop in body fat, reduction of mucus in the body, heightened sense of smell and taste, improvement in appearance of nails, no build-up of film on teeth, increase in oxygen absorption, improvement of sleep quality, faster recovery from workouts and improvements in athletic ability. There is also research that shows because fruits are packed with vitamins and anti-oxidants, including vitamin C and beta-carotene, consumption of fruit can reduce risk of cancer as well as other chronic diseases.
In 1979, Professor Alan Walker, a Johns Hopkins University paleoanthropologist, reported that preliminary studies of unmarked tooth enamel in early hominoids suggested that pre-human ancestors apparently had a diet of mostly fruit. Walker said, "I don't want to make too much of this yet. But it is quite a surprise."
In 1971, a short-term study by B. J. Meyer was published in the South African Medical Journal describing how lipid profiles and glucose tolerances improved on a particular fruitarian diet. An earlier 1971 study by Meyer tested a 45-year-old teacher who claimed she had eaten only fruits for the past 12 years, who was found to be in "excellent health". In a further trial in the study, body weights of overweight subjects showed a tendency to "level off" at the "'theoretically ideal' weight". In 2014, a study was done by Lorenza S. Colzato, Amnelies M. de Haan and Bernhard Hommel to test the affect Tyrosine (an amino acid found if fruits and vegetables like apples and carrots) had on cognitive control and creativity. Participants were given doses of Tyrosine and then asked to complete creativity tasks.The study found that Tyrosine helps to stop processes that negatively impact cognitive control resources, and that it promotes convergent (deep) thinking. Because convergent thinking tends to require more cognitive top down control, the findings of this study suggests that Tyrosine can facilitate control-hungry creative operations, hence the foods a person consumed may affect the way they think. Therefore, the supplementation of Tyrosine or Tyrosine containing diets, such as a fruitarian diet, may promote convergent thinking, supporting creative processes.
According to nutritionists, adults must be careful not to follow a fruit-only diet for too long, a fruitarian diet is not suitable for teens, and a fruitarian diet is wholly unsuitable for children.
Fruitarianism is more restrictive than veganism or raw veganism. Maintaining this diet over a long period can result in dangerous deficiencies, a risk that many fruitarians try to ward off through nutritional testing and vitamin injections. The Health Promotion Program at Columbia University reports that a fruitarian diet can cause deficiencies in calcium, protein, iron, zinc, vitamin D, most B vitamins (especially B12), and essential fatty acids.
Despite the fact that fruits are healthy and provide a source of carbohydrates, they have very little protein, and because protein can’t be stored in the body like fat and carbohydrates, fruitarians need to be careful that they consume enough protein each day. When the body doesn’t take in enough protein, it misses out on amino acids, which are essential to making body proteins which support the growth and maintenance of body tissues. Consuming high levels of fruit also poses a risk to those who are diabetic, or pre-diabetic due to the negative affect that the large amounts of sugar in fruits has on blood sugar levels. These high levels of sugar means that fruitarians are at high risk for tooth decay. Another concern that fruitarianism presents is that because fruit is easily digested, the body burns through meals quickly, and is hungry again soon after eating. A side effect of the digestibility is that the body will defecate more frequently. Additionally, the Health Promotion Program at Columbia reports that food restrictions in general may lead to hunger, cravings, food obsessions, social disruptions, and social isolation. The severe dietary restrictions inherent in eating strictly low-carb or fruitarian regimes also carry the serious risk of triggering orthorexia nervosa.
Vitamin B12, a bacterial product, cannot be obtained from fruits. According to the U.S. National Institutes of Health "natural food sources of vitamin B12 are limited to foods that come from animals." Like raw vegans who do not consume B12-fortified foods (certain plant milks and breakfast cereals, for example), fruitarians may need to include a B12 supplement in their diet or risk vitamin B12 deficiency.
Growth and development issues
In children, growth and development may be at risk. Some nutritionists state that children should not follow a fruitarian diet. Nutritional problems include severe protein-energy malnutrition, anemia and deficiencies including proteins, iron, calcium, essential fatty acids, raw fibre and a wide range of vitamins and minerals.
Some notable advocates of fruitarianism, of diets which may be considered fruitarian, or of lifestyles including such a diet, are:
- August Engelhardt,
- Arnold Ehret,
- Raymond W. Bernard, and
- Essie Honiball adhered to a fruitarian diet for some time.
- Actor Ashton Kutcher told USA Today that his pancreas levels went "all out of whack" after following a fruitarian diet in preparation for his role as Apple CEO and onetime fruitarian Steve Jobs, in the film Jobs. Jobs died of pancreatic cancer.
Others such as Ross Horne and Viktoras Kulvinskas appeared to only describe the fruitarian diet. Some, like Johnny Lovewisdom, experimented with different diets, including juicy fruitarianism, liquidarianism (juices only), vitarianism (fruit, vegetables, raw dairy) and breatharianism.
Others like author Morris Krok, who at stages during his life, lived "only on fruits", allegedly advised against a diet of "only fruit", although it was subsequently reported that Krok's diet consisted of "just fruit", with dietary practices of fruitarians as varied as definitions of the term 'fruitarianism'. Diet author Joe Alexander lived for 56 days on juicy fruits.
- Idi Amin, the Ugandan military dictator, became a fruitarian in Saudi Arabia during his exile there.
- Mohandas Karamchand Gandhi, better known as Indian political and spiritual leader Mahatma Gandhi, sustained a fruitarian diet for 5 years. He apparently discontinued the diet and went back to vegetarianism due to pleurisy, a pre-existing condition, after pressure from a Dr. Jivraj Mehta.
- Ben Klassen, white supremacist, founder of the Creativity Movement, and author of The White Man’s Bible, advocated a fruitarian diet to include fruits, vegetables and nuts.
- Steve Jobs, who supposedly named his company Apple because he was experimenting with a fruitarian diet.
