Fats by: Hanna, Letizia, Bella

Fats • Fats contain three kinds of atoms: carbon, hydrogen and oxygen • A fat molecule is made out of four molecules joined together. One is glycerol attached to to it are three molecules called fatty acids.

Macrnutrients • Macronutrients are enviromental substances used for energy, groth. . . • Those are needed in large amounts • Carbohydrates (55%), Fats (30%), Proteins ((15%)

Function of Fats • • Provide energy Absorb and store vitamins Fat can be stored for subsequent use Fats help maintain a constant body temperature (thermal insulation)

Sources of saturated Fats Animal based products: dairy foods: butter, milk, cheese meat palm oil, coconut milk and cream, cooking magerine big amounts of saturated • Manufactured and packaged foods: fats are linked with heart diseases and high blood • fatty snack foods (chips) cholesterol levels (solid at • fried and high fat foods ( pizza, room temperature) hamburgers) • cakes, muffins, pastries, pies • sweet and savoury pastries Saturated fats raise your LDL cholesterol level • •

Sources of unsaturated Facts Polyunsaturated fats: • omega-3 fats (fish) • omega-6 fats (oils, soybean oil, nuts) Monusaturated fats: • found in olive oil, avocados, nuts) Unsaturated fats lower LDL and raise HDL colesterol important for a healthy diet help reduce risk of heart disease and lower cholesterol levels when they replace saturated fats in the diet

Trans Fats • • unsaturated fats that act like saturated fats increase the level of "bad" (LDL) cholestrol decrease the level of "good" (HDL) cholestrol found in processed foods (butter, magerine) 7

Cholesterol • found in food (eggs) and in blood • important function in our body, but having high levels of the wrong cholesterol type in the blood increases the risk of heart disease (saturated fats) • LDL: low density lipoprotein (bad cholesterol) carry lipids from liver to other areas • HDL: high density lipoprotein (good cholesterol) carry lipids from organs to the liver for recycling • VLDL: very low density lipoprotein are even more critical than LDL 8
