Rapeseed oil
Rapeseed oil is extracted from the black seeds of the yellow-flowering rape plant. Rapeseed oil is unsaturated fat and high in monounsaturated fat, making it a healthier type of oil. It is rich in Vitamin E and Omega 3,6, and 9 fats.
It is available as refined and unrefined. In the UK, oil labelled 'vegetable oil' is usually refined rapeseed oil. Unrefined rapeseed oils are labelled 'cold-pressed', 'premium', 'virgin' or extra virgin' and have a delicate nutty flavour.
Rapeseed oil is great for frying, but it is important to use as little oil as possible and cook at lower temperatures.

Saturated fats
Saturated fats are normally solid at room temperature, for example, red palm oil, lard or beef dripping. They generate fewer aldehydes when heated but might carry other risks.
Coconut oil is extremely high in saturated fat. The refined version is the best of all to cook with.
