Forks for eating were not in widespread usage in Europe until the early modern period , and early on were limited to Italy. We looked at two plans from eDiets — one that offers support alone, and another with meal delivery. When possible, rich hosts retired with their consorts to private chambers where the meal could be enjoyed in greater exclusivity and privacy. The term " dessert " comes from the Old French desservir , "to clear a table", literally "to un-serve", and originated during the Middle Ages. Support is available through phone counseling, weekly e-classes with a dietician and tracking tools. Marzipan in many forms was well known in Italy and southern France by the s and is assumed to be of Arab origin. Its production also allowed for a lucrative butter export from the 12th century onward.
Rates of self-reported Seventh-day Adventists SDA were less than half of those of the general population, and, among SDA, vegetarians had lower rates of diabetes than non-vegetarians. Among possible explanations for a protective effect of vegetarian diet are the Lower BMI of vegetarians and higher fiber intake, both of which improve insulin sensitivity.
The relationship between vegetarian diet and bone health remains unclear. According to some studies, a vegetarian lifestyle can be associated with vitamin B 12 deficiency and low bone mineral density. The China-Cornell-Oxford Project ,  a year study conducted by Cornell University , the University of Oxford , and the government of China has established a correlation between the consumption of animal products and a variety of chronic illnesses, such as coronary heart disease , diabetes , and cancers of the breast , prostate and bowel see The China Study.
A British study of almost 10, men found that those who gave up meat were almost twice as likely to suffer from depression as people on a conventional balanced diet. The study found that the committed vegetarians studied had a higher average depression score compared to others. A vegetarian diet may help reduce the risk of Alzheimer's disease, as the most important dietary link to Alzheimer's disease appears to be meat consumption, with eggs and high-fat dairy also contributing.
Western vegetarian diets are typically high in carotenoids , but relatively low in omega-3 fatty acids and vitamin B Protein intake in vegetarian diets is lower than in meat diets but can meet the daily requirements for most people.
Proteins are composed of amino acids , and a common concern with protein acquired from vegetable sources is an adequate intake of the essential amino acids , which cannot be synthesised by the human body. While dairy and egg products provide complete sources for ovo-lacto vegetarian , several vegetable sources have significant amounts of all eight types of essential amino acids, including lupin beans , soy ,  hempseed , chia seed ,  amaranth ,  buckwheat ,  pumpkin seeds  spirulina ,  pistachios ,  and quinoa.
A study found a varied intake of such sources can be adequate. Vegetarian diets typically contain similar levels of iron to non-vegetarian diets, but this has lower bioavailability than iron from meat sources, and its absorption can sometimes be inhibited by other dietary constituents. However, the American Dietetic Association states that iron deficiency is no more common in vegetarians than non-vegetarians adult males are rarely iron deficient ; iron deficiency anaemia is rare no matter the diet.
According to the United States National Institutes of Health , vitamin B 12 is not generally present in plants and is naturally found in foods of animal origin. The recommended dietary allowance of B 12 in the United States is, per day, 0. Plant-based, or vegetarian, sources of Omega 3 fatty acids include soy , walnuts , pumpkin seeds, canola oil , kiwifruit , hempseed , algae , chia seed , flaxseed , echium seed and leafy vegetables such as lettuce, spinach , cabbage and purslane.
Purslane contains more Omega 3 than any other known leafy green. Olives and olive oil are another important plant source of unsaturated fatty acids. Plant foods can provide alpha-linolenic acid which the human body uses to synthesize the long-chain n-3 fatty acids EPA and DHA. While the health effects of low levels of EPA and DHA are unknown, it is unlikely that supplementation with alpha-linolenic acid will significantly increase levels.
Calcium intake in vegetarians and vegans can be similar to non-vegetarians, as long as the diet is properly planned. Non-dairy milks that are fortified with calcium, such as soymilk and almond milk can also contribute a significant amount of calcium in the diet.
Vitamin D needs can be met via the human body's own generation upon sufficient and sensible exposure to ultraviolet UV light in sunlight. Vitamin D 2 , or ergocalciferol is found in fungus except alfalfa which is a plantae and created from viosterol , which in turn is created when ultraviolet light activates ergosterol which is found in fungi and named as a sterol from ergot.
Any UV -irradiated fungus including yeast form vitamin D 2. Claims have been made that a normal serving approx. There have been many comparative and statistical studies of the relationship between diet and longevity, including vegetarianism and longevity. A metastudy combined data from five studies from western countries. Regular meat eaters had the base mortality rate of 1.
The study reported the numbers of deaths in each category, and expected error ranges for each ratio, and adjustments made to the data. However, the "lower mortality was due largely to the relatively low prevalence of smoking in these [vegetarian] cohorts". Out of the major causes of death studied, only one difference in mortality rate was attributed to the difference in diet, as the conclusion states: In Mortality in British vegetarians ,  a similar conclusion is drawn:.
British vegetarians have low mortality compared with the general population. Their death rates are similar to those of comparable non-vegetarians, suggesting that much of this benefit may be attributed to non-dietary lifestyle factors such as a low prevalence of smoking and a generally high socio-economic status, or to aspects of the diet other than the avoidance of meat and fish.
The Adventist Health Studies is ongoing research that documents the life expectancy in Seventh-day Adventists.
This is the only study among others with similar methodology which had favourable indication for vegetarianism. The researchers found that a combination of different lifestyle choices could influence life expectancy by as much as 10 years.
The researchers concluded that "the life expectancies of California Adventist men and women are higher than those of any other well-described natural population" at The life expectancy of California Adventists surviving to age 30 was The Adventist health study is again incorporated into a metastudy titled "Does low meat consumption increase life expectancy in humans?
Statistical studies, such as comparing life expectancy with regional areas and local diets in Europe also have found life expectancy considerably greater in southern France, where a low meat, high plant Mediterranean diet is common, than northern France, where a diet with high meat content is more common.
A study by the Institute of Preventive and Clinical Medicine, and Institute of Physiological Chemistry looked at a group of 19 vegetarians lacto-ovo and used as a comparison a group of 19 omnivorous subjects recruited from the same region. The study found that this group of vegetarians lacto-ovo have a significantly higher amount of plasma carboxymethyllysine and advanced glycation endproducts AGEs compared to this group of non-vegetarians.
According to studies by the Permanente Journal and the National Institute for Health NIH , vegetarian diets are affordable and can help reduce health risks like high blood pressure, cardiovascular disease, and cholesterol levels. A plant based diet has the potential to lower the risk of heart disease as well as reducing the amount of medications prescribed in instances of chronic illness. A change to a plant based diet, or vegetarianism, has had dramatic positive effects on the health of patients with chronic illnesses, significantly more than exercise alone .
Vegetarian diets have been studied to see whether they are of benefit in treating arthritis , but no good supporting evidence has been found.
Certain alternative medicines , such as Ayurveda and Siddha , prescribe a vegetarian diet as a normal procedure. Maya Tiwari notes that Ayurveda recommends small portions of meat for some people, though "the rules of hunting and killing the animal, practiced by the native peoples, were very specific and detailed".
Now that such methods of hunting and killing are not observed, she does not recommend the use of "any animal meat as food, not even for the Vata types". The human digestive system is omnivorous , capable of consuming a wide variety of plant and animal material. The American Dietetic Association has presented evidence that vegetarian diets may be more common among adolescents with eating disorders.
At the same time the association cautions however, that the adoption of a vegetarian diet may not necessarily lead to eating disorders, rather that "vegetarian diets may be selected to camouflage an existing eating disorder". Vegetarianism is associated with increased risk of depression, anxiety, and somatoform disorder, although causality cannot be established.
Various ethical reasons have been suggested for choosing vegetarianism, usually predicated on the interests of non-human animals. In many societies, controversy and debate have arisen over the ethics of eating animals. Some people, while not vegetarians, refuse to eat the flesh of certain animals due to cultural taboo , such as cats, dogs, horses or rabbits. Others support meat eating for scientific, nutritional and cultural reasons, including religious ones.
Some meat eaters abstain from the meat of animals reared in particular ways, such as factory farms , or avoid certain meats, such as veal or foie gras. Some people follow vegetarian or vegan diets not because of moral concerns involving the raising or consumption of animals in general, but because of concerns about the specific treatment and practises involved in the raising and slaughter of animals, i.
Others still avoid meat because meat production is claimed to place a greater burden on the environment than production of an equivalent amount of plant protein. Ethical objections based on consideration for animals are generally divided into opposition to the act of killing in general, and opposition to certain agricultural practices surrounding the production of meat.
Princeton University professor and animal rights activist Peter Singer believes that if alternative means of survival exist, one ought to choose the option that does not cause unnecessary harm to animals.
Most ethical vegetarians argue that the same reasons exist against killing animals in the flesh to eat as against killing humans to eat, especially humans with cognitive abilities equal or lesser than the animals in question. Singer, in his book Animal Liberation , listed possible qualities of sentience in non-human creatures that gave such creatures the scope to be considered under utilitarian ethics , and this has been widely referenced by animal rights campaigners and vegetarians.
Ethical vegetarians also believe that killing an animal, like killing a human, especially one who has equal or lesser cognitive abilities than the animals in question, can only be justified in extreme circumstances and that consuming a living creature for its enjoyable taste, convenience, or nutrition value is not a sufficient cause.
Another common view is that humans are morally conscious of their behaviour in a way other animals are not, and therefore subject to higher standards. McMahan stated that cognitively disabled human do not possess the same rights as non-disabled humans. While mentally disabled people were in the past often treated with extreme brutality, with the progression of morality most people understand that the rights of the cognitively disabled still include a right to life and kind treatment.
Increasingly, as moral philosophy progresses further, people understand that, outside of survival situations, denying the right to life to animals with equal or greater cognitive abilities than mentally disabled humans is an arbitrary, discriminatory practice based on habit and desire as opposed to logic.
Opponents of ethical vegetarianism argue that animals are not moral equals to humans and so consider the comparison of eating livestock with killing people to be fallacious. This view does not excuse cruelty, but maintains that animals do not possess the rights a human has. One of the main differences between a vegan and a typical vegetarian diet is the avoidance of both eggs and dairy products such as milk, cheese, butter and yogurt.
Ethical vegans do not consume dairy or eggs because they state that their production causes the animal suffering or a premature death. To produce milk from dairy cattle , calves are separated from their mothers soon after birth and slaughtered or fed milk replacer in order to retain the cows milk for human consumption. A dairy cow's natural life expectancy is about twenty years.
In battery cage and free-range egg production, unwanted male chicks are culled or discarded at birth during the process of securing a further generation of egg-laying hens. Ethical vegetarianism has become popular in developed countries particularly because of the spread of factory farming , faster communications, and environmental consciousness.
Some believe that the current mass demand for meat cannot be satisfied without a mass-production system that disregards the welfare of animals, while others believe that practices like well-managed free-ranging and consumption of game, particularly from species whose natural predators have been significantly eliminated, could substantially alleviate the demand for mass-produced meat. Ancient Greek philosophy has a long tradition of vegetarianism. Pythagoras was reportedly vegetarian and studied at Mt.
Carmel, where some historians say there was a vegetarian community , as his followers were expected to be. Roman writer Ovid concluded his magnum opus Metamorphoses , in part, with the impassioned argument uttered by the character of Pythagoras that in order for humanity to change, or metamorphose , into a better, more harmonious species, it must strive towards more humane tendencies. He cited vegetarianism as the crucial decision in this metamorphosis, explaining his belief that human life and animal life are so entwined that to kill an animal is virtually the same as killing a fellow human.
Everything changes; nothing dies; the soul roams to and fro, now here, now there, and takes what frame it will, passing from beast to man, from our own form to beast and never dies Therefore lest appetite and greed destroy the bonds of love and duty, heed my message! Never by slaughter dispossess souls that are kin and nourish blood with blood! Jainism teaches vegetarianism as moral conduct as do some major  sects of Hinduism.
Buddhism in general does not prohibit meat eating, while Mahayana Buddhism encourages vegetarianism as beneficial for developing compassion. Sikhism    does not equate spirituality with diet and does not specify a vegetarian or meat diet. Theravadins in general eat meat. In the Theravada canon, Buddha did not make any comment discouraging them from eating meat except specific types, such as human, elephant meat , horse, dog, snake, lion, tiger, leopard, bear, and hyena flesh  but he specifically refused to institute vegetarianism in his monastic code when a suggestion had been made.
In several Sanskrit texts of Mahayana Buddhism , Buddha instructs his followers to avoid meat. Christians have always been free to make their own decisions about what to eat; however, there are groups within Christianity that practice specific dietary restrictions for various reasons.
Surviving fragments from their Gospel indicate their belief that — as Christ is the Passover sacrifice and eating the Passover lamb is no longer required — a vegetarian diet may or should be observed. However, orthodox Christianity does not accept their teaching as authentic. Indeed, their specific injunction to strict vegetarianism was cited as one of the Ebionites' "errors". At a much later time, the Bible Christian Church founded by Reverend William Cowherd in followed a vegetarian diet.
They have also sponsored and participated in many scientific studies exploring the impact of dietary decisions upon health outcomes. Additionally, some monastic orders follow a vegetarian diet, and members of the Orthodox Church follow a vegan diet during fasts. The association grew in prominence during the 19th century, coupled with growing Quaker concerns in connection with alcohol consumption, anti-vivisection and social purity.
The association between the Quaker tradition and vegetarianism, however, becomes most significant with the founding of the Friends' Vegetarian Society in "to spread a kindlier way of living amongst the Society of Friends. According to Canon Law , Roman Catholics are required to abstain from meat defined as all animal flesh excluding water animals on Ash Wednesday and all Fridays of Lent including Good Friday.
Canon Law also obliges Catholics to abstain from meat on the Fridays of the year outside of Lent excluding certain holy days unless, with the permission of the local conference of bishops, another penitential act is substituted. The restrictions on eating meat on these days is solely as an act of penance and not because of a religious objection to eating meat.
Since the formation of the Seventh-day Adventist Church in the s when the church began, wholeness and health have been an emphasis of the Adventist church, and has been known as the "health message" belief of the church. Obedience to these laws means abstinence from pork, shellfish, and other animals proscribed as " unclean ". The church discourages its members from consuming alcoholic beverages , tobacco or illegal drugs compare Christianity and alcohol.
In addition, some Adventists avoid coffee , tea , cola , and other beverages containing caffeine. The pioneers of the Adventist Church had much to do with the common acceptance of breakfast cereals into the Western diet, and the "modern commercial concept of cereal food" originated among Adventists.
His development of breakfast cereals as a health food led to the founding of Kellogg's by his brother William. In both Australia and New Zealand , the church-owned Sanitarium Health and Wellbeing Company is a leading manufacturer of health and vegetarian-related products, most prominently Weet-Bix.
Research funded by the U. National Institutes of Health has shown that the average Adventist in California lives 4 to 10 years longer than the average Californian. The research , as cited by the cover story of the November issue of National Geographic , asserts that Adventists live longer because they do not smoke or drink alcohol, have a day of rest every week, and maintain a healthy, low-fat vegetarian diet that is rich in nuts and beans.
He cites the Adventist emphasis on health, diet, and Sabbath-keeping as primary factors for Adventist longevity. Though there is no strict rule on what to consume and what not to, paths of Hinduism hold vegetarianism as an ideal.
However, the food habits of Hindus vary according to their community, location, custom and varying traditions. Historically and currently, those Hindus who eat meat prescribe Jhatka meat,  while some Hindus believe that the cow is a holy animal whose slaughter for meat is forbidden. Some followers of Islam, or Muslims, chose to be vegetarian for health, ethical, or personal reasons. However, the choice to become vegetarian for non-medical reasons can sometimes be controversial due to conflicting fatwas and differing interpretations of the Quran.

Jenny Craig has a good track record for short-term weight loss up to one year. In a UC San Diego clinical trial of dieters funded by Jenny Craig , Jenny Craig clients lost 11 percent of their initial weight after 12 months, compared with 3 percent weight loss by those who were dieting on their own.
The "doctor-designed" Bistro M. The price is a cut above the competition, too. The plan tries to help you avoid a weight-loss stall out by varying the daily calorie intake between 1, and 1, By eating a little more some days and a little less on others, you'll supposedly prevent your body from becoming used to the same number of calories every day.
While no university studies support the theory that varying caloric intake aids weight loss, the high quality of the food and the relatively large portion sizes have been praised by Health magazine, Dr. Phil and The New York Times. Some plan users have complained of a lack of choices and menu flexibility compared to other plans, but a company spokesman says they offer more than entrees and can make substitutions to accommodate allergies and food preferences.
It's a reasonable price for well-made food with slightly faster average weight loss than with Jenny Craig. This meal-delivery service, endorsed by Marie Osmond and Dan Marino, emphasizes foods with a low glycemic index. The underlying premise is that controlling blood sugar levels leads to weight loss. The heat-and-eat prepared meals and snacks contain roughly 55 percent "good" carbs, 25 percent protein, and 20 percent fats; like Jenny Craig, you add fruits, vegetables and dairy.
Support is available through phone counseling and online chat rooms. There's plenty of research showing that following a diet of 1, to 1, calories a day, such as Nutrisystem, can cause weight loss. For example, a study by the Obesity Research Center at St. Luke's Roosevelt Hospital in New York found that postmenopausal women who followed a 1,calorie plan for 16 weeks lost an average of 21 pounds. For a meal-delivery diet system, Nutrisystem is more economical than Jenny Craig. Although today's program is not as stringent as the original liquid fast Medifast launched decades ago, the low-fat, relatively low-carb plan is designed to bring about rapid weight loss by coaxing your body into a "fat-burning state" known as ketosis.
The 70 meal replacement choices include shakes, bars, soups, pudding, oatmeal, chili, pretzel sticks, cheese puffs, and scrambled eggs. If you can stick with it, a diet of 1, calories a day can certainly induce rapid weight loss. A common concern with such low-calorie diets is that you'll quickly regain the weight, but in a small clinical trial recently published in the journal Experimental Biology , after 10 months, only about one in five people regained all the weight they had lost.
Choose this more extreme plan only if quick weight loss is your priority. Within hours of posting a seven-second video of their son learning to walk, Whitney and Adam Dinkel were flooded with messages.
