2. 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.

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

4. 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)

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

6. 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

7. 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)

8. 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
