‘good fats’
monounsaturated and polyunsaturated fats
‘bad fats’

what is the function of fats?
fats are required for the development and maintenance of cell membranes (which control the transport of nutrients and waste in and out of the cells) as well as acting as a fuel being a source of energy.
how are trans fats created?
through hydrogenation when liquid oil is converted into fat
what affects on health does monounsaturated fats have?
they assist in lowering LDL cholesterol (bad cholesterol) therefore decreasing risk of atherosclerosis and cardiovascular disease.
food sources of monounsaturated fats
olive oil, canola oil, nuts and avocardo
what affects on health does polyunsaturated fats have?
they assist in lowering LDL cholesterol (bad cholesterol) and increasing the HDL cholesterol (good cholesterol), decreasing risk of heart attack and stroke. It also increases elasticity of blood vessels, decreasing risk of blood clots, heart attack and stroke
food sources of polyunsaturated fats
tuna, salmon, nuts, canola oil
what are the two types of polyunsaturated fats
omega3 and 6
what affects on health does trans fats have?
they increase levels of LDL cholesterol and hence increase the likelihood of cardiovascular disease being developed later in life and can also interfere with cell membranes and contribute to high blood glucose levels and potentially lead to type 2 diabetes.
what affects on health does saturated fats have?
they increase levels of LDL cholesterol and hence increase the likelihood of cardiovascular disease being developed later in life
food source of trans fats
processed foods such as pastries, cakes and margarine
food source of saturated fats
animal products and fatty meats like beef chops, wagu, full cream milk, cheese, biscuits
