Being vegetarian long-term prevents major illnesses
The benefits of vegetarianism were promoted long ago by Shakyamuni Buddha more than 3,000 years ago. More recently, a medical doctor wrote a book called Why should we be Vegetarian which emphasizes the medical benefits of a vegetarian diet. Following a vegetarian diet in the long-term leads to fewer serious illnesses, and even if you do become ill, it will be more easily treated and you will recover sooner than others.
