Everyone should be become vegetarian because they not do no need to eat meat to have a healthy diet. Do you agree or disagree?

The rapid and widespread rise in the number of people with serious illnesses, that making people today more aware of health. Many people think that the staple food in the daily diet should be vegetables and fruits. I agree with this view but besides that you have to add other necessary nutrients from animal meat.

One of the striking benefits of vegetarianism is reduce the incidence of diseases such as cancer, diabetes, cardiovascular disease.Because a vegetarian diet is associated with a higher consumption of fiber, folic acid, vitamins C and E, magnesium, unsaturated fat, and countless phytochemicals that help vegetarians have lower cholesterol, being thinner, having lower blood pressure. Equally vegetarianism helps you spare a lot of money. The plant are cheaper than the meat food products. To illustrate this, you spend $10 for food, with this cost you can buy consist of carrot, salad, tomato, cucumber, orange or apple while you just buy 1 kg pork or poultry for the same money.

Though the advantages of being a vegan are very obvious but just eat vegetable and fruit not enough energy for activities daily. Meat is a very efficient deliverer of protein. Because the muscles of animals and humans share the same components, eating animal tissue is an easy way to get this necessary nutrient. Athlete's diet contains very meat because it firms muscles and provides energy for the body. Furthermore, meat is made up a specialty and usual meal of some nation. For example, Svið which a dish from Iceland, cook by lamb or Grilled turkey is a traditional dish served Thanksgiving at America and Canada.

It seems to me that, the vegetarian are good tendency but daily diet should be combination of foods that the people can eat to get the full nutrients.
