Some people think everyone should be a vegetarian，because we do not need to eat meat to have a healthy diet. To what extent do you agree or disagree？
People have different views about whether being vegetarians or vegans is more beneficial for human beings. Some people believe that being a vegetarian is better since meat is helpless for people to stay healthy：I doubt this statement as people have right to choose whether to be a vegetarian or not and meat is a regular part of our diet.
Although leading a low carbon life and being a vegetarian is quite popular in our society，it does not mean everyone should only eat vegetables in their daily diet. Actually，to some groups of people，a single dietary structure will even injure their fitness. For instance，children growth may be affected by unbalanced diet and some people may be allergic to plants like caraway and celery. Also，if a pregnant woman refuses to take any meat，her baby would suffer from malnutrition to a high degree.
Meanwhile，it is well- recognized that meat provide a wide range of nutrients that are difficult to obtain in adequate quantities from vegetables and fruits. Insufficient intake of those nutrients will produce negative health problems，such as poor growth. People cannot keep fit without any meat foods. Meat is high in protein and other essential nutrients，and these nutrients are hardly to find alternatives in plant source foods. Therefore，a diet with a good combination of meat and vegetable is thought to have considerable value.
In brief，not all people should be a vegetarian and balanced diet will be the best choice for individuals.
