背景1)There are many types of vegetarians.Vegetarians, by today’s definition, are individuals who do not eat meat, and other animal products, such as cheese and yogurt and any part of the egg.2)Reasons of being vegetarians for the present vegetarians: most vegetarians avoid animal products because of health issues(obesity,Diabetes), cultural or religious reasons.3)The battle between vegetarians and non-vegetarians has a long history. And the number of the vegetarians is increasing in today’s society. A study shows shocking results: vegetarian men reduced their risk of early death by 50%! Women vegetarians benefit from a 30% reduction in death.四辩稿Let’s go straight to the point. What the other team has been emphasizing is they believe that vegetarianism is a healthier lifestyle than a normal diet. According to their view, meats have been condemned for the trend to heart disease and various cancers. But is it really that meat causes us to be unhealthy?Chicken and fish in itself have not been shown to cause chronic diseases, but when the chicken and fish are deep fried in partially hydrogenated oil, they become one of the most potent causes of heart disease as they then contain trans fatty acids.The truth of the matter is, food processing and various artificial ingredients, what’s more, the amount of salt, are much more likely to be contributing to health detriments than a healthful steak or lamb shank. While everyone believes meats and dairies have become unhealthy, the truth is quite the opposite. Meat consumption can actually lead to a decreased risk of various medical conditions and can help to maintain weight. So what really harms is the processing of meat, not the meat itself. Secondly, the other team has always mentioned that we can supplement the nutrients with other vegetarian foods. Well, it’s not impossible, but is it really easy to do that? For example, if we need protein, we can eat more beans to supplement the protein, but eating more beans will also bring side effects such as rickets and gall- stone. In fact, eating too much specific kind of food for a long time will bring certain health risks. What we really need is a balanced diet, especially for college students. Teenagers need more nutrition to keep normal development. And most of the nutrition come from some microelements, which are rich in meat but fewer in vegetables. When we can eat meat directly to get these nutrients, why do we have to waste time looking for other foods to replace the meat when we still don’t know its side effects.Thirdly, the other team also believe that vegetarianism is on behalf of kind of sympathy for animals. They believe that animals have lives ,then what about the plants? They can kill or eat plants casually, what about the lives of plants? Do they think animal life is nobler than plants? According to the natural selection, some of the creatures on the earth will inevitably become food for other creatures. Appealing in the name of sympathy for stopping eating meat is too hypocritical. If so, I believe that there is nothing in the world that we can eat because everything has lives just in different ways. The difference between our human beings and other animals lies in our feelings and wisdom. Human will begin to pursue spiritual progress after already meeting our basic survival needs. This is the development trend of human civilization. Therefore, it is our consistent opinion to treat animals in a humanitarian, gentle manner. We agree that animal feeding conditions and slaughter conditions should be improved to reduce animal suffering, but we don’t think we can give up eating meat just because of so-called sympathy for animals.What’s more, If everyone becomes a vegetarian, the fish-farmer and pig or cattle raisers will lose their jobs, because people no longer need fish, pork, beef and other kind of meat. No meat life will make many industries disappear, such as animal husbandry, breeding industry, food processing industry and even many catering services. All these industries will go bankrupt and it will bring massive loss to the economy of the country. Some people will say that we can use the production of vegetarian products to fill the gaps in these positions but they have overlooked how large the scale of the meat industry chain is.In summary, vegetarianism is not really worthy of our promotion. Everyone can choose the eating diet they like, but when we want to promote it as a healthy lifestyle, it needs more science evidence to support. It isclear that vegetarianism doesn’t have enough. Our college students, because of shallow experience, we are a group that is more impulsive and blindly follow the trend. It is obviously not a mature decision to advocate vegetarianism for this group.1.肉类不一定致癌Meat Probably Doesn't Cause CancerOne of the most touted reasons to steer clear of meats — particularly those high in saturated fats — is the alleged increased risk of cancer and heart disease. Not only were cases of cancer, heart disease, AND obesity much lower during decades like the 1950s — where meat was a staple of every mealtime — recent research has shown that both saturated fat and cholesterol actually pose benefits to the body. According to Authority Nutrition, cholesterol is an essential molecule and yes that includes both HDL (or "good cholesterol") and LDL (otherwise known as "bad cholesterol"). "When we get a lot of cholesterol from the diet, the liver just produces less of it instead, so the total amount doesn't change much. In fact, in about 70% of people, cholesterol has negligible effects on cholesterol in he blood. In the other 30% (termed hyper-responders), there is a mild elevation in LDL cholesterol, but HDL (which is protective) also goes up." Authority Nutrition goes on to note that saturated fats can be beneficial by "decreasing risk of stroke" and results from studies and data collection have aggregated to show that saturated fats do not have an impact on cancer risks and heart disease.2.Don't oppose carnivorism and vegetarianism. Isn't it veganism must be carnivorous? We do not advocate eating meat every day, but we do not advocate eating meat at all.3.Bad for some special group of people, like teenagers and the sports men.1)Teenagers need more nutrition to keep normal development. And most of the nutrition comefrom some microelements, which are rich in meat but fewer in vegetables. And lacking of those microelements is bad for the normal growth and development of the teenagers.2)The sports lovers do a lot of physical exercises, so they need more energy than ordinary people.And meat will provide a great deal of calories that the sportsmen needed. However, vegetables can not provide so many nutrition for these people who need a lot of energy in a short time. 4.Vegetarianism Does Not Necessarily Help With Weight Loss素食主义并不有助于减肥Many people have taken to vegetarianism not for political reasons, but for weight loss reasons, as vegetarianism has been touted as a great weight loss regimen. This is not necessarily the case. In fact vegetarianism can actually lead to weight gain.The reality is that you don't necessarily have to be healthy to be a vegetarian. You just have to exclude meat (and dairy as well if you are a vegan). My ex boyfriend the vegetarian had a steady diet of vodka, tofurkey, hash browns, and Oreos (which are completely vegan, by the way) to support his vegetarian lifestyle. In other words, he wasn't in the best of health. Vegetarianism and veganism do not provide the same satiation that a diet including meat does. Because meats provide complete proteins as well as fat, you will feel fuller longer. In fact, met actually can aid in a weight-loss program and even expedite benefits gained during exercise. According to Men's Health, "When you eat, your body has to expend calories to digest the food. Protein causes this inner fire to burn the hottest, followed by carbohydrates, followed by fat. Animal proteins increase thermogenesis more than vegetable proteins, so the best calorie-burning foods are lean meats. So eat some protein at each meal—build your dinner around lean chicken, beef, or pork. That way, you're burning the most calories through digestion at the end of the day, when your metabolism is slower."5.Not Eating Meat Is Bad For The EnvironmentI can empathize with those who are put off by the idea of eating meat due to both their love of animals, and the abhorrent conditions of some (some not all) farming industries. The fact of the matter is, however, notonly do we currently have a choice of selecting meats and dairy products that are from farming industries that allow "free-range" and do not include the use of hormones or GMOs, but to eschew killing cattle for meat production would actually be detrimental to our environment. Yes, that's right, the methane produced from livestock is more potent than the deadly gas known as carbon monoxide. Moreover, soy and tofu products have always been regaled in vegetarianism (I don't know if there's a single person that orders tofu without a self-important grin plastering their face. Hey, I've been guilty of it myself) but tofu production actually exacerbates environmental harm. According to a study from Cranfield University, "Switching from British-bred beef and lamb to meat substitutes imported from abroad such as tofu and Quorn would increase the amount of land cultivated, raising the risk of forests being destroyed…The researchers concluded: ‘A switch from beef and milk to highly refined livestock product analogues such as tofu could actually increase the quantity of arable land needed to supply the UK.'"。
