Transcript

  • 1. Fat is the most concentrated source of food energy, and has 9 calories in
  • 2. Unsaturated Fat: Liquid at room temperature; ALSO KNOWN AS OIL Examples: canola oil, olive oil, vegetable oil, etc. Saturated Fat Solid at room temperature Examples: lard, butter, shortening.
  • 3. Fat consumption for a standard 2,000 calorie diet… *No more than 66 grams TOTAL FAT. *No more than 30% of total calories should come from fat. *No more than 10% or 22 grams saturated fat *No more than 20% or 44 grams monounsaturated and polyunsaturated fat
  • 4. CALORIES FAT: FROM STEP 1: Grams fat per serving multiplied by 9 STEP 2: Divide by total calories Honey3: Multiply by 100 to give percentage STEP Grahams: Serving = 2 crackers Calories = 130 Protein = 2 grams Carbs. = 21 grams Fat
  • 5. Cholesterol…. Cholesterol is NOT fat, but a “fat-like” substance present in all body cells. It contributes to the digestion of fat and the absorption of fat soluble vitamins. Cholesterol is manufactured by the body mostly in the liver!
  • 6. All animals make cholesterol… ANY animal food or animal food bi-product including red meat, poultry and fish, will ultimately raise total body cholesterol. Foods high in cholesterol include: Egg Yolks
  • 7. LDL’s and HDL’s Cholesterol circulates in the blood in chemical “carriers” called lipoproteins….. There are two major kinds of lipoproteins: LDL’s (Low-Density Lipoprotein) = LOSERS HDL’s (High-Density Lipoprotein) = HEROES
  • 8. Low-Density Lipoproteins LDL’s are BAD for our bodies! = LOSERS! LDL’s take cholesterol from the liver to wherever it is needed in the body. Because of LDL’s - excess amounts of cholesterol can build up in artery walls leading to heart disease, stroke and even death!
  • 9. High-Density Lipoproteins HDL’s are GOOD for our bodies! = HEROES! HDL’s carry excess cholesterol back to the liver – keeping it from causing artery cholesterol buildup
  • 10. Fatty Acids: *Organic acids units that make up fat… Saturated / Unsaturated Polyunsaturated Monounsaturated Trans Fatty Acids
  • 11. Saturated and Unsaturated Fatty Acids Raises the level of LDL cholesterol in the bloodstream! Food sources: meat, poultry skin, whole-milk dairy products, tropical oils-coconut oil, palm oil, and palm kernel oil.
  • 12. Polyunsaturated Fatty Acids Lowers TOTAL blood cholesterol – including both LDL and HDL levels! Food sources: many vegetable oils, such as corn oil, soybean oil and safflower oil. Soy beans and oil Safflower and oil Corn oil
  • 13. Monounsaturated Fatty Acids Lowers LDL cholesterol and Raises HDL cholesterol! Food sources: Olives, olive oil, avocados, peanuts, peanut oil and canola oil.
  • 14. Hydrogenation: The process in which missing hydrogen atoms are added to an UNSATURATED FAT (oil) making it more firm in texture forming a new fatty acid called Trans Fatty Acid containing many of the same properties as saturated fats.
  • 15. Fat in Food… Invisible Fat: Fat that is not easily seen in foods… Visible Fat: Fat that can be easily seen…
