I can become a vegetarian not a vegan

I am confused between vegetarian and vegan so I clarified two notions through the search engine. According to Google, vegetarians do not eat fish, meat, or poultry, however, they can eat eggs and dairy. Vegans also do not eat meat, but they can not eat eggs and dairy. In this sense, I can consider becoming a vegetarian because I can eat dairy food and eggs even if I can not eat meat. Eating a proper amount of meat is good for health. On the other hand, eating too much meat can cause bad diseases in the body. Even if vegans and vegetarians can not eat meat, they are different. Vegetarians can supplement nutrients that can be gained from meat through eggs and dairy.
