In the past, people usually ate meat but in the present people tend to eat more vegetables and some of them become vegetarians. Because of the increase of vegetarian in the world, so we will compare vegetarians to normal diet in four topics.
First, we are talk about the nutrient. Vegetables are rich in nutrient such as amino acids, sugar, mineral, starch. These nutrients can change into the substance or the energy for body needed, but you must use various types of vegetable to get all complete nutrition because each type of vegetable contains nutrients insufficient for the body's need. Unlike the normal diet that received enough nutrient for body's need. People should not be eating vegetarian is pregnant women and children in the age of growth.
Second, the topic will be related to the disease. Vegetarian tend to live longer because a vegetarian diet decrease mortality rate from cardiovascular disease than meat-eaters, who get more saturated fat intake, and a vegetarian diet also helps lowering blood pressure, prevent hypertension, and thus reduce the risk of stroke. However, saturated fats can help strengthen the immune system and the nervous system. And vegetarian diet may receive inadequate nutrition if they do not eat enough vegetables to provide essential nutrients.
Third, It is about morality. Vegetarians think that it is cruel and unethical to kill animals for food because it can feel stress, fear and pain like a human. In the United States, they kill about 35 million cows, 115 million pigs, and 9 billion birds for food each year but meat eater doesn't think like that. Meat eater thinks eating meat is the natural part of the circle life and actually plant that vegetarian eat is the one type of living thing too.
In our opinion vegetable is good for health and normal diet is good for health too. If you eat it appropriately you will get all of the essential nutrients for life. If you want to live longer, you should not forget to exercise and get more sleep. You will have a good health.
