What are sunflower, soya, sesame and corn oils all examples of? 

Polyunsaturated fatsFat can be divided into two main groups - saturated and unsaturated. Saturated fat is found in lard, butter, hard margarine, cheese, whole milk and anything that contains these ingredients, such as cakes and pastries. Its also the white fat you can see on meat and underneath poultry skin.No more than 1/3 of our total fat intake should come from saturated fats. Trans Fats (Hydrogenated Vegetable Oils) are also found in processed foods like pastries, cakes and biscuits. Eating too much saturated fat is associated with increased blood cholesterol concentrations and an increased risk of heart disease.

Eating less helps to minimise the risks it poses to heart health. Unsaturated fats are healthier fats, generally found in plant foods such as fruits, seeds, nuts and vegetables. They can be divided into Polyunsaturated (PUFA) and Monounsaturated (MUFA) and each should provide around 1/3 of our fat intake. - Polyunsaturated fats include: Sunflower, soya, sesame, and corn oils - Monounsaturated fats include: Olive and rapeseed oils.
