There is good meat in hamburgers. Why is it still considered unhealthy?

How to judge whether a food is healthy depends on raw materials, cooking methods and so on. The simplest, overnight meal, with meat and vegetables, can this be judged as healthy food? I can't. Just like a hamburger, first of all, the chicken in it is instant chicken, which is not fed normally, but grows up quickly with hormones, and this raw material is unhealthy. Secondly, the meat is still fried, and we dare not draw a conclusion whether the oil is clean or not, but we all know that eating too much fried food is easy to cause cancer. In addition, the fat content of things such as cream added in hamburgers is also very high. After a whole hamburger, high-fat and high-calorie things are not good for people's health. Therefore, just because it contains meat and vegetables, it cannot be concluded that it is a healthy food. Hamburgers can be eaten occasionally to relieve appetite, but it is not recommended to eat more.
