Which oil should/shouldn't I use to fry food?

Olive oil is considered to be the healthiest of all of the cooking oils, the problem with olive oil is that it can not take the heat, it has what is called a low smoke level which makes it unsuitable for frying.

Canola oil has long been labeled as the oil of choice because it is high in monounsaturated fat and low in saturated fat which makes it desirable, saturated fats are the "bad fats" and "monounsaturated fats" are the good fats, it also has a high resistance to heat (high smoke level).

Lately however there has been a lot of controversy over Canola oils health benefits. I would recommend doing research on all oils to form your own opinion. 

Peanut oil is considered to be one of the best for healthy deep fryers because it is a natural oil that is high in monounsaturated fat, low in saturated fat and has a good resistance to heat.

Oil is an important part of the healthy fryer puzzle, some types are better than others because of the types of fat they contain. Another very important part of the picture is fat absorption. Regardless of the type of cooking oil used, oil absorption is a critical factor, as you have already guessed less is better.

I hope you have enjoyed this and think twice before reaching for that oil to fry foods.
