Demystifying the Fats Caitriona Lordan Dietitian

Saturated Fat 17% reduction in CVD No effect on risk of dying

Saturated Fat Different types of saturated fatty acids Some but not all implicated in cholesterol elevation Myristic, Palmitic and Lauric increase LDL cholesterol Stearic has no effect

Butter Myristic acid 12%(increases LDL) Palmitic acid31%(increases LDL) Stearic acid11%(no effect) Other SFAs11% Alpha linolenic 1%(no effect) Oleic acid24%(decreases LDL) Palmitoleic 4% (decreases LDL) Linoleic 3% (decreases LDL)

Rapeseed oil Palmitic 4%(increases LDL) Stearic 2%(no effect) Alpha linolenic10% (no effect) Oleic 61%(decreases LDL) Linoleic21% (decreases LDL)

Olive oil Palmitic7.5-20%(increases LDL) Stearic0.5-5%(no effect) Alpha Linolenic0-1.5%(no effect) Oleic 55-83%(decreasesLDL) Linoleic3-21%(decreases LDL)

What about Coconut oil??? Myristic14-18%(increases LDL) Palmitic % (increases LDL) Lauric45-48%(increases LDL) Stearic5%(no effect) Oleic6-8.2%(decreases LDL) Linoleic1-2%(decreases LDL)

Saturated Fat Causes endothelial damage Increases platelet activity but Omega 3 fatty acids suppress platelet aggregation
