What is the benefit of olive oil compared to other vegetable oil? Is it any good to prepare all your food with olive oil if you can afford it?
Olive oil is a healthy choice because it is low in saturated fat and high in unsaturated fat. But it is quite expensive and there are other oils that are also good choices.
All oils contain varying proportions of different forms of fat. Saturated and unsaturated fats are the main types.
As well as aiming to cut down on fat, we should also be trying to replace saturates with unsaturates.
There are two types of unsaturated fat, polyunsaturates and monounsaturates. Polyunsaturates, and to a lesser extent, monounsaturates, have been shown to lower blood cholesterol levels and therefore help in reducing the risk of heart disease.
Rapeseed oil, which like olive oil contains mostly monounsaturated fat, is a good and cheaper alternative to olive oil. Sunflower, soya bean and corn oil all contain mostly polyunsaturated fat so are also good choices.
Some oils are labelled as vegetable oil or blended vegetable oils. All of these are also low in saturated fat and are generally cheaper.
But remember, whichever unsaturated oil you use, try to use as little as possible. It can help to measure oil for cooking with tablespoons rather than pouring straight from a container and you can gradually try to reduce the number of spoonfuls you use
