Is It Healthy to Eat at Home?

I have read somewhere that it might be healthier to eat at home instead of eating out. I know that it sometimes might not be possible to always eat at home especially if you work, but on the other hand it might be worth to make sure that you eat a home-made meal as often as it is possible. Even though I like to eat out from time to time, I also like to eat at home. When I cook at home, I have an opportunity to choose exactly those ingredients for my meals that are healthy. I do not use a lot of oil or grease in my kitchen. Probably this is one of the reasons my meals are healthier. I cannot have control over what I eat when I eat out, but from time to time I do not mind eating something that is less healthy but might be tastier than things that I cook at home.
