Section 8—Nutrition: Eating for Optimal Health

Slide 2

Assess Yourself Complete the appraisal on page 244

Slide 3

Nutrition Essential Nutrients: Body gets from nourishment since it can't produce by any stretch of the imagination, or sufficiently quick Proteins, fats, sugars, vitamins, minerals, and water

Slide 4

Calories Which of the key supplements give calories? Calories: A unit of measure that shows the measure of vitality acquired from a specific sustenance.

Slide 8

Proteins Form vital parts of muscles, bones—likewise blood, compounds, a few hormones, and cell layers Building pieces of protein—amino acids 20 normal—9 are key & 11 can be created by the body Can give vitality to the body 4 calories for each gram

Slide 9

Protein Complete: Individual protein sources are finished on the off chance that they supply ALL of the vital amino acids in satisfactory sums. Exp: meat, angle, poultry, eggs, drain, cheddar, and soy Incomplete: Do not supply the greater part of the key amino acids in sufficient sums. Exp: Plant sources, for example, vegetable and nuts Good wellsprings of most vital amino acids, yet normally low in maybe a couple

Slide 10

Protein Adequate prescribed day by day allow: .36 gram for every pound Or ~ 56g of protein for every day for guys and 46g for females Possible sources: 3 ounces of incline meat, poultry, angle = 20-25g some tofu = 20-25g some dry beans 15-20g some drain or yogurt or 1 ½ oz. of cheddar = 8-12g oats, grains, nuts, and vegetables = ~ 2-4g/serving

Slide 13

Protein Consumed past what we need can be combined into fat for vitality stockpiling or smoldered for vitality needs. 10-35% of your aggregate day by day caloric admission Remember that frequently protein sources are higher in fat as well

Slide 14

Fats Usable vitality Help protect body, pad organs, temperature control Help your body assimilate fat-dissolvable vitamins Flavor/surface to nourishments Acceptable Macronutrient Distribution Ranges (AMDR) 20-35% every day

Slide 15

Fats Major fuel amid rest and light movement Certain fats keep up circulatory strain and advance of solid pregnancy Most fats in sustenance are as triglycerides

Slide 17

Basic Cooking Fats All fats have a similar number of calories. 9 cal/gram Food fats more often than not have both soaked and unsaturated—prevailing sort decides qualities: Saturated: strong at room temperature Unsaturated: fluid at room temperature Saturated: Primarily creature fat—meats, poultry, eggs, spread (d o have imperative unsaturated fats, yet use in littler sums)

Slide 18

Basic Cooking Fats Unsaturated fats: Mostly plant sources Monounsaturated: Many helpful impacts for the body, for example, keeping corridors free from aggravation. Exp: Olive, sesame, shelled nut, avocado oil

Slide 19

Unsaturated Fats (cont) Polyunsaturated: Vegetable oils, for example, soybean, safflower, corn, sunflower. Since dairy cattle, pigs, chickens are all encouraged such a great amount of corn rather than the grass they once ate, we get vast amounts of this as of now.

Slide 20

Fats Omega-3 unsaturated fats Form of polyunsaturated fat Found basically in fish (2+ X/week) Lesser sums in some plant sources (vegetables/nuts) Heart solid advantages Reduce propensity of blood to cluster Inhibit irritation and strange heart rhythms Reduce pulse and danger of heart assault and stroke in a few

Slide 21

Fats Omega-6 unsaturated fats: Form of polyunsaturated fat Some nutritionists prescribe diminishing the extent of Omega-6's agreeable to Omega-3's Sources: corn oil and soybean oil Livestock bolster Used in margarine, serving of mixed greens dressing and mayonnaise

Slide 23

Figure 8.5

Slide 24

Fats and Health Fat 25-35% (AMDR 20-35%) of aggregate day by day calories 7% from immersed fat 10% from polyunsaturated fat 20% from monounsaturated fat Cholesterol Total Cholesterol 200mg/dl or less High Density Lipo-Protein (HDL's) more than 60 mg/dl Low Density Lipo-Protein (LDL's) less than 130 mg/dl

Slide 25

Trans-Fatty Acids Soybeans, corn, sunflower seeds, rapeseed (canola), safflower seeds, cottenseeds pounded Refined with concoction solvents: freshening up specialists and blanches—starts the procedure of the oils great unsaturated fats A little measure of a metal impetus added to the oil—as a rule nickel Hydrogen gas included under high weight and high temperatures End item is plastic/thicker and can hold a shape—not an oil any longer

Slide 26

Trans-Fatty Acids TFA's connected to coronary illness, diabetes, corpulence (since 1990's—Harvard) The Institute of Medicine at the National Academy of Sciences (2002) "no sheltered level of human utilization… upper admission level of ZERO"

Slide 27

Fats Trans-unsaturated fats and soaked fat raise LDL (low thickness lipoprotein) Unsaturated and monounsaturated may bring down LDL and raise HDL (high thickness lipoprotein) In vast sums trans-unsaturated fats may bring down HDL

Slide 28

Fats Trans fats on sustenance marks by 2006 Can promote trans-fat free with a little measure of trans-fat in the item Watch the fixing names

Slide 29

Trans-Fatty Acids Watch for these things on the nourishment name under fixings: Partially hydrogenated vegetable oil Mono hydrogenated margarine Partially hydrogenated oils Margarine Shortening Vegetable shortening

Slide 30

Carbohydrates Supply vitality to body cells Some phones, for example, those in the cerebrum and different parts of the sensory system and blood utilize carbs for fuel

Slide 31

Carbohydrates Types: Simple Carbs: sugar, nectar, foods grown from the ground (1-2 sugar units/atom) Complex Carbs: Grains, grain items, potatoes, and vegetables (chains of sugar particles) Starches: grains, vegetables, tubers Dietary fiber: grains, organic products, vegetables Refined (handled) Unrefined (entire grains)

Slide 32

During assimilation in the mouth and small digestive tract, starches and twofold sugars separated into single sugar particles—glucose—for ingestion Once glucose in the circulatory system—pancreas discharges the hormone insulin—which permits cells to take up glucose and utilize it for vitality The liver and muscles additionally take up glucose to give sugar stockpiling as glycogen.

Slide 33

Carbohydrates Before preparing: Inner layer of germ Middle layer—endosperm Outer layer of wheat Digest all the more gradually, enter the circulation system all the more gradually, feel full speedier/longer Always search for "entire" as the main word on the fixings list

Slide 34

Carbohydrates After handling: Germ and grain evacuated Leaving boring endosperm (now white flour or may say "advanced") Retain the greater part of the calories of entire grain Much lower in fiber, vitamins, minerals, other gainful mixes

Slide 35

Carbohydrates 55% of aggregate calories (ADMR 45-65%) basic carbs 15% of aggregate calories point of confinement to under 10% included sugars—discharge calories

Slide 36

Dietary Fiber Plant substances that are nondigestible Dietary (present actually in plants) Functional (disengaged from characteristic sources or integrated in a lab and added to a nourishment) Pass through the intestinal tract and give mass to excrement Decreases obstruction, hemorrhoids, and diverticulitis Slows purging of stomach, moderates development of glucose into the blood, lessens retention of cholesterol

Slide 37

Dietary Fiber Recommendations: 38 grams day by day guys; 25 grams for females Americans all in all exclusive devour about a large portion of this sum Processing can expel fiber- - so eat natural products, vegetables, vegetables, entire grains

Slide 38

Table 8.2

Slide 39

Recommended Grams Per Day Based on a 2200 Cal Per Day Fats: 30% of calories for each day 2200 X 30% = 660 calories 660/9 cal/per/gram = 73 grams for every day Proteins: 15% of calories for each day 2200 X 15% = 330 calories 330/4 calories for each gram = 83 grams for each day Carbs: 55% of calories for each day 2200 X 55 =1210 calories 1210/4 calories for each gram = 303 grams for every day

Slide 40

Glycemic Index Theory is that high-glycemic file sustenances are separated rapidly, hence bringing about a fast ascent in glucose Insulin kicks into move the sugar from the blood into the phones where it is required Blood sugar drops Signals hunger Person needs to eat once more

Slide 41

Glycemic Index Low GI = 55 or less Medium GI = 56 - 69 High GI = at least 70 Example: GI database Need more research on sustenances

Slide 42 (USDA) Food direction framework that advances solid nourishment decisions and physical action Choosing an adjust of servings from various nutrition types addresses supplement issues and diminishes endless ailment chance Balancing sustenance decisions and action advances weight administration
