1. FAT

3. We Need Fat Dietary fat is one of three macronutrients (along with protein and carbohydrates) that provide energy for your body Fat is essential to your health because it supports a number of your body's functions Some vitamins, for instance, must have fat to dissolve and nourish your body (fat soluble)

4. We Need Fat Fat provides flavor and texture to help prevent food from being bland and dry Provides back-up energy if blood sugar supplies run out (after 4-6 hours without food) Provides insulation under the skin from the cold and the heat

5. Fat Guidelines Age GroupTotal Fat Limits Children ages 2 - 330% - 35% of total calories Children and adolescents age 4 - 18 25% - 35% of total calories Adults age 19 and older20% - 35% of total calories

6. Box 17 WHAT IS YOUR UPPER LIMIT ON FAT FOR THE CALORIES YOU CONSUME? Total Calories per DaySaturated Fat in GramsTotal Fat in Grams 1,60018 or less53 2,000*20 or less65 2,20024 or less73 2,500*25 or less80 2,80031 or less93 *Percent Daily Values on Nutrition Facts Labels are based on a 2,000 calorie diet. Values for 2,000 and 2,500 calories are rounded to the nearest 5 grams to be consistent with the Nutrition Facts Label.

8. Fat Guidelines – Trans Fat You should try to avoid trans fat completely The American Heart Association recommends limiting trans fat to no more than 1 percent of your total daily calories For most people, this is less than 2 grams a day at the most !!!

9. Fat Guidelines – Bottom Line Although amount of fat is important, more about “types” of fat than amount Choose healthy fats Limit saturated fat Avoid trans fat

10. Saturation Types of Fat - Saturation A saturated fatty acid has no double bonds A monounsaturated fatty acid has one double bond A polyunsaturated fatty acid has two or more double bonds

12. Saturated Fats Solid at room temperature Found in Beef and pork fat Coconut oil Palm kernel oil Whole milk ButterCheese Cocoa butter

13. Saturated Fat Saturated fat may increase your risk of heart disease and type 2 diabetes Replace saturated fats with healthier monounsaturated fats and polyunsaturated fats, found in olive oil, canola oil, vegetable oils, lean poultry, and unsalted nuts and seeds

14. Monounsaturated Fats Liquid at room temperature Have 1 (mono) double bond Found in: Olive oil Canola oil Peanut oil Cashews

15. Polyunsaturated Fats Liquid at room temperature Have more than 1 (poly) double bond Found in: Canola oil Corn oil Soybean oil Safflower oil Sunflower oil Cottonseed oil

16. Shape of Fats Unsaturated fats have kinky, fluid and flexible chains – easier to break down Saturated fats have straight and rigid chains – harder to break down – they buildup in your arteries Shape affects health

17. Trans Fats

18. Cis fatty acids have hydrogens located on the same side of the double bond Trans fatty acids have hydrogens located on opposite sides of the double bond

20. Hydrogenation When hydrogen is added to a mono- or polyunsaturated fat, a liquid oil becomes solid at room temperature. =

21. Hydrogenation Benefits of hydrogenation Makes fats more stable, with longer shelf-life Alters texture of foods (flaky pie crusts) A cheap alternative to using butter or perishable oils for food manufacturers

22. Hydrogenation Negatives of hydrogenation/trans fats: Makes unsaturated fat (good) act like saturated fat in the body (bad) Like saturated fat, trans fat causes LDL (bad) cholesterol to go up Trans fats ALSO lower HDL (good) cholesterol “Trans” fats may be more detrimental to heart health than naturally-occurring saturated fats

24. Label Tricks! There are 3 servings in 1 bag! Serving size: 3 tbsp (makes 4 cups popped) When providing nutrition info, they give you info for 3 tbsp, but only 1 cup popped (instead of 4) 180 calories/serving (540 in a bag) 13g fat/serving (39g in a bag) 2.5g sat. fat/serving (7.5g in a bag) 5 Grams Trans Fat Per Serving! (15g in a bag)

25. Does This Have Trans Fat? Yes it does! We’ll see how in a minute!

26. Trans Fat Labeling January, 2006: Trans Fat Labeling Required by Law Here’s the tricky part: FDA food labeling rules make it possible for consumers to exceed their maximum recommended daily intake of trans fats even if they eat only foods labeled "zero trans fats" per serving. How?

27. Trans Fat Labeling According to the FDA, a product claiming to have “zero trans fat” can actually contain up to a half gram of trans fat per serving ! So they make the serving size smaller!!! Read the ingredients! “Hydrogenated = Trans Fat”

28. Does This Have Trans Fat?

29. Where Are Trans Fats Found? MargarinesShortening Pie Crusts and Pie Crust Mixes Tortillas and tortilla chips Potato chips Flavored popcorn Commercial cookies, cakes

30. Where Are Trans Fats Found? DoughnutsCrackersGranolaPastries Biscuit, muffin and cake mixes Fried foods (French fries, fried chicken)

31. Should Trans Fats Be Banned?

32. Essential Fatty Acids These are fatty acids the body can’t make; they must be consumed in the diet to meet the body’s needs. Help regulate cell function Regulate blood clotting, inflammation, vasodilation/constriction

33. Omega 3 and Omega 6 Fatty Acids Omega 3 means the first double bond is 3 carbons back from the methyl end of the chain Omega 6 means the first double bond is 6 carbons back

34. Linolenic Acid Omega 3 (Linolenic Acid) A member of the Omega 3 fatty acid family Used to make EPA and DHA These reduce the risk of heart disease, hypertension, arthritis, cancer Found in flaxseed oil, canola oil, fatty fish (salmon, tuna, mackerel), leafy greens, soy, beans, walnuts

35. Omega 6 (Linoleic Acid) A member of the Omega 6 fatty acid family Found in vegetable oils, some nuts

36. Essential F.A. Deficiency It is possible to have a deficiency of linoleic and linolenic acids Symptoms include: Flaky, itchy skin Growth retardation Poor wound healing Depression?
