Fried food may be bad as they say

Since I was young, frying food was already a part of our culture. Until now fried foods are dominating the dining table in our country. In our home we usually fry fish, chicken, pork and sometimes even vegetables like eggplant and okra (lady finger).

This question is nagging my mind since a long time ago. If fried food is bad for the health then why are people still frying their food? Take the case of the fried chicken, it is one of the favorites here. You can check KFC for proof of that.
