Many people all around the world simply love fried and junk food. Even though, nowadays, most of you avoid this kind of food, some of them simply cannot imagine a day without this food. You should know that frying is not healthy and it is better to start cooking, because this way you will prevent the development of harmful substances.
When frying, most people use the same oil twice or even more times, for preparing many different dishes. This is not healthy, and if you do it very often it can lead to appearance of carcinogen-acrolein. That is why it is necessary to avoid consuming hot dogs, sausages and other products made from the worst kind of meat.
Also you must never use animal based oils when frying. Instead you can use coconut oil, because it is one of the healthiest oils and it has many great advantages. Coconut oil has very few calories, therefore it is very good for people who want to lose weight.
