1Major Functions of Dietary Fat
energy source at rest, Insulation, protective layer around organs, metabolism of “fat soluble” vitamins: A,D, E, K
2Saturated Fats
solid at room temperature, animal foods and tropical oils, elevates blood cholesterol levels (LDL)
3Unsaturated fats
liquid at room temperature, from plant sources and fish (except when you eat animal foods with unsat.), lowers blood cholesterol (LDL), raises HDL ((Omega 3 and fatty acids from fish))
4Sources of Saturated Fats
beef, pork, dairy products, palm oil, coconut oil
5Source of unsaturated fats
avocado, olives, peanuts, soybeans, corn oil, safflower oil, sunflower oil, fish (omega-3)
6Reccomended Dietary Intake of Saturated Fats
Less than 10%
7Reccomended Dietary Intake of Unsaturated Fats
Less than 20%
8How many calories per gram in fats?
9
9Artificial fats in foods
sorbitol, olestra, simplese
10Health Risk of High Fat Diet
Artery Disease (fatty build up), diabetes, colon or rental cancer, high calories = excess body fat
11Cholesterol
waxy substance found oily in animal products and produced in the liver. Necessary for cell membranes and nerve linings and hormones
12High Density Lipoproteins (HDL(Fats carrying protein))
carries cholesterol away from body to be extrected (good)
13Low Density Lipoproteins
Carries cholesterol into the body and sticks to vessels (bad)
14Measurement of Blood Cholesterol by blood sample
requires 12 hour fasting
15Blood Cholesterol level Reccomendations
Less than 300 mg per day; (HDL 70, LDL 130)
16Average Blood Cholesterol level in American Diet
600-800 mg
17Factors that Elevate Blood Cholesterol
High amounts of saturated or trans fats in diet; increasing LDL
18Factors that Elevate Blood Cholesterol (2)
Exercise, Not Smoking, Unsaturated oils in diet; elevate HDL
19Hydrogenation
when an unsaturated fat "corn oil" is turned saturated (Food processing technique that partially hardens the plant oil, changing an unsaturatd fat to saturated and resulting in trans fat raising your LDL)
20Partially Hydrogenated
corn oil has been chemically altered from good to bad
21Trans fatty acids
Found in commercially prepared foods with partial hydrogenation
22Examples of Trans fatty acids
cookies, crackers, french fries, microwave popcorn (increases LDL)
23Protein
From a combo of 23 amino acids (functional units of proteins)
24Major Functions of Proteins
Formation of body tissues (muscles, hair, skin, nails) and blood clotting and hormone production
25Essential Amino Acids
9-10 of the 20 These amino acids cannot be made in the body and must be supplied in the diet
26Non Essential Amino Acids
10 of the 20 These are made in the body
27What is needed for the functions of Protein to occur in the body?
All 20 amino acids at the same time within the body
28Complete Food Sources of Amino Acids (Contain all 10 Essential AA's)
Animal Foods (Fish, poultry, meats, eggs, dairy, soybean (tofu))
29Incomplete Food Sources of Amino Acids (Lack certain in Essential AA's)
Any single plant food, vegetables, grains, nuts
30Reccomended Dietary Intake of Protein
15-20% of total calories
31Calories per gram in Protein
4
32Bio Zone Diet
Higher % of Protein (40% of protein, 40% of carbs, 20% of fat)
33Amino Acids Supplements
Expensive Options but not necessary with balanced diet
34Branched Chain Amino Acids
Leucine, Isoleucine, Valine
35Branched Chain Amino Acids Benefit
Help Decrease exercise induced muscle damage, increase muscle recovery, reduce fatigue (higher intensity)
36Time to have branched chain Amino Acids
30 minutes post exercise
37Post exercise branched chain amino acids
15 grams idealy whey protein (quicker uptake) and atleast 2-3 grams of LEucine for any benefit (Roasted Peanuts, Lean beef, chicken breast, tuna, salmon, turkey)
38Vegetarian Diet for Amino Acids
Has to mix and match to get all essential amino acids (Example, peanut butter sandwhich (Bread1-5 , Peanut Butter 6-9))
