A practical limitation of the glycemic index is that it does not measure insulin production due to rises in blood sugar. While adding fat or protein will lower the glycemic response to a meal, the relative differences remain. 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. A vegetarian diet which is poorly planned can lead to hyperhomocysteinemia and platelet disorders; this risk may be offset by ensuring sufficient consumption of vitamin B 12 and polyunsaturated fatty acids. Though some more traditional Muslims may keep quiet about their vegetarian diet, the number of vegetarian Muslims is increasing. Additionally, some monastic orders follow a vegetarian diet, and members of the Orthodox Church follow a vegan diet during fasts.

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. Though some more traditional Muslims may keep quiet about their vegetarian diet, the number of vegetarian Muslims is increasing. The former Indian president Dr. Abdul Kalam was also famously a vegetarian.

Many non-vegetarian Muslims will select vegetarian or seafood options when dining in non- halal restaurants. However, this is a matter of not having the right kind of meat rather than preferring not to eat meat on the whole. Followers of Jainism believe that all living organisms whether they are micro-organism are living and have a soul, and have one or more senses out of five senses and they go to great lengths to minimise any harm to any living organism.

Most Jains are lacto-vegetarians but more devout Jains do not eat root vegetables because they believe that root vegetables contain a lot more micro-organisms as compared to other vegetables, and that, by eating them, violence of these micro-organisms is inevitable.

So they focus on eating beans and fruits, whose cultivation do not involve killing of a lot of micro-organisms. No products obtained from dead animals are allowed, because when a living beings dies, a lot of micro-organisms called as decomposers will reproduce in the body which decomposes the body, and in eating the dead bodies, violence of decomposers is inevitable.

Jain monks usually do a lot of fasting, and when they knew through spiritual powers that their life is very little, they start fasting until death. Some Jains do not consume plant parts that grow underground such as roots and bulbs, because the plants themselves and tiny animals may be killed when the plants are pulled up.

While classical Jewish law neither requires nor prohibits the consumption of meat, Jewish vegetarians often cite Jewish principles regarding animal welfare , environmental ethics , moral character, and health as reasons for adopting a vegetarian or vegan diet. A number of medieval rabbis e. Many modern rabbis, by contrast, advocate vegetarianism or veganism primarily because of concerns about animal welfare, especially in light of the traditional prohibition on causing unnecessary "pain to living creatures" tza'ar ba'alei hayyim.

According to Genesis , consumption of meat was prohibited to human beings 1: Some advocates of Jewish vegetarianism, such as Rabbi Abraham Isaac Kook , describe vegetarianism as an eschatological ideal to which all human beings must eventually return.

Jewish vegetarianism and veganism have become especially popular among Israeli Jews. In , Israel was described as "the most vegan country on Earth", as five percent of its population eschewed all animal products. Within the Afro-Caribbean community, a minority are Rastafari and follow the dietary regulations with varying degrees of strictness. The most orthodox eat only " Ital " or natural foods, in which the matching of herbs or spices with vegetables is the result of long tradition originating from the African ancestry and cultural heritage of Rastafari.

I will keep that in mind!! Last edited by mod-anon; at Please use the Quick Reply button instead of Quote Reply. Well I have to say that I have been on NS for a week now and I really am feeling quite good about it! I like the food so far and haven't had any issues. I want to lose 40 lbs and I weighed in Monday and I lost 7!! It is so easy to do this plan I only wish I would have done it sooner. I know some of the weight is probably water but I'll take it! I have been working out about x week drinking lots of water, eating my meals, lots of fruits and veggies.

Feeling really good overall. This is really teaching me portion control. I was def eating way to big portions before. I will keep you posted on next weeks weigh in! Ok, here's my input: I have tried every diet out there-seriously. Nutrisystem was horrible for me. I didn't like the food I rememeber one soup smelled exactly like dog food. I stuck to it for 2 weeks tho and didn't lose anything. I knew that I could not rely on pre-packaged foods and the only way I would be happy and get my healthy foods in would be WW.

It has the highest success rate for people losing and keeping it off, plus it's one that doctors will always recommend. I started in January and down 35lbs already. I can eat and drink what I want-which is the reality of life anyway, not eating pre-packaged foods! My opinion is if you try WW and it does nothing for you, then you din't follow the program exactly how you are supposed to.

Lastly, to lose healthy you should lose no more than 2 lbs a week. Slow but steady winds the race! You can lose fast other ways but it WILL come back. I have lost 7 lbs so far. I did a typo in my previous message of I am happy with this program.

I like the idea of no measuring food out. I know exactly what to eat to get my calories in. I really think this program teaches you portion control so when you do go back to eating the regular foods you know how much you should eat. I have been eating very healthy I also feel very good. I have tried WW before and it didn't work for me.

Not to say other people wouldn't have success For me though I think this is the way to go right now. I am doing it for 3 months and then going on maintenenance. Actually NS has lots of recipes and stuff for when you do maintenance to keep you within the calorie limits also.

So far this is the only thing I have tried where I actually am losing every week and at a healthy loss of about 2 lbs a week!

Good luck to you! Last edited by lam; at Iam, I'm not surprised that you're happy with NutriSystem. What's not to be happy about? It's something new and exciting and you're losing weight! It's probably like a vacation too, from having to fix a meal from scratch. Here comes the big however. The truly important thing is the long term result. I remember when Oprah Winfrey was on NutriSystem. It was played up as the greatest thing going.

After being on it for a long time, she came out on stage one day looking really great thin waistline etc. A lower glycemic response usually equates to a lower insulin demand but not always, and can improve long-term blood glucose control [11] and blood lipids. The insulin index is also useful for providing a direct measure of the insulin response to a food. The glycemic index of a food is defined as the incremental area under the two-hour blood glucose response curve AUC following a hour fast and ingestion of a food with a certain quantity of available carbohydrate usually 50 g.

The AUC of the test food is divided by the AUC of the standard either glucose or white bread, giving two different definitions and multiplied by The average GI value is calculated from data collected in 10 human subjects.

Both the standard and test food must contain an equal amount of available carbohydrate. The result gives a relative ranking for each tested food. The current validated methods use glucose as the reference food, giving it a glycemic index value of by definition. This has the advantages of being universal and producing maximum GI values of approximately For people whose staple carbohydrate source is white bread, this has the advantage of conveying directly whether replacement of the dietary staple with a different food would result in faster or slower blood glucose response.

A disadvantage with this system is that the reference food is not well-defined, because there is no universal standard for the carbohydrate content of white bread. GI values can be interpreted intuitively as percentages on an absolute scale and are commonly interpreted as follows:. A low-GI food will cause blood glucose levels to increase more slowly and steadily, which leads to more suitable postprandial after meal blood glucose readings.

A high-GI food causes a more rapid rise in blood glucose level and is suitable for energy recovery after exercise or for a person experiencing hypoglycemia. The glycemic effect of foods depends on a number of factors, such as the type of starch amylose versus amylopectin , physical entrapment of the starch molecules within the food, fat and protein content of the food and organic acids or their salts in the meal — adding vinegar , for example, will lower the GI.

In general, coarse, grainy breads with higher amounts of fiber have a lower GI value than white breads. While adding fat or protein will lower the glycemic response to a meal, the relative differences remain.

That is, with or without additions, there is still a higher blood glucose curve after a high-GI bread than after a low-GI bread such as pumpernickel. Fruits and vegetables tend to have a low glycemic index. The glycemic index can be applied only to foods where the test relies on subjects consuming an amount of food containing 50 g of available carbohydrate.

Carrots were originally and incorrectly reported as having a high GI. This has been refuted by brewing industry professionals, who say that all maltose sugar is consumed in the brewing process and that packaged beer has little to no maltose present. Dietary replacement of saturated fats by carbohydrates with a low glycemic index may be beneficial for weight control , whereas substitution with refined, high glycemic index carbohydrates is not.

Several lines of recent [] scientific evidence have shown that individuals who followed a low-GI diet over many years were at a significantly lower risk for developing both type 2 diabetes , coronary heart disease , and age-related macular degeneration than others.

Postprandial hyperglycemia is a risk factor associated with diabetes. A study shows that it also presents an increased risk for atherosclerosis in the non-diabetic population [30] and that high GI diets, high blood-sugar levels more generally, [31] and diabetes [32] are related to kidney disease as well. Conversely, there are areas such as Peru and Asia where people eat high-glycemic index foods such as potatoes and high-GI rice without a high level of obesity or diabetes.

A study from the University of Sydney in Australia suggests that having a breakfast of white bread and sugar-rich cereals, over time, can make a person susceptible to diabetes, heart disease, and even cancer.

The American Diabetes Association supports glycemic index but warns that the total amount of carbohydrate in the food is still the strongest and most important indicator, and that everyone should make their own custom method that works best for them.

The International Life Sciences Institute concluded in that because there are many different ways of lowering glycemic response, not all of which have the same effects on health, "It is becoming evident that modifying the glycemic response of the diet should not be seen as a stand-alone strategy but rather as an element of an overall balanced diet and lifestyle.

A systematic review of few human trials examined the potential of low GI diet to improve pregnancy outcomes. Potential benefits were still seen despite no ground breaking findings in maternal glycemia or pregnancy outcomes.
