Which is healthier, KFC or McDonald's? Why?

None of them are good, because they can't tell who is good and who is bad, but they are harmful to human body. Whether it is fried, fried or roasted, it is equally unhealthy and has no benefit to the human body. The only advantage is that they are regarded as a snack food when others are free. Of course, we can't completely reject it, but we should try to avoid its temptation. In short, not eating is the healthiest.
