Polyunsaturated fat

Polyunsaturated fat is a ‘good fat’ of the unsaturated kind, but should still only appear minimally in the diet (constituting approximately no more than seven per cent of the diet.) There are two main features of polyunsaturated fat; omega-3 and omega-6 (essential fatty acids). Sources of such fat are sunflower oil, salmon, nuts, mackerel and wholegrains. Polyunsaturated fat has been shown to lower blood cholesterol levels and consequently help reduce the risk of heart disease, while improving brain health, vision and strong bones.
