1 The Exchange System By Aimee Clem, R.D. Graduate Student, Nutrition Central Washington University
2 The Exchange System: What is it? Food classification methodCreated for diabetics by ADA & ADATrack Calories, CHO’s, PRO, FATHealthy way of eatingFoods are placed into food groups based on chemical composition.For instance, in the FGP, what is in the dairy group? Well, eggs and cheese are high protein and are therefore in the meat group in the exchange system.3. Can be a healthy, balanced way of eating for most people.
3 Athlete Nutrition Awareness of macronutrient composition Allows dietitian/nutritionist to estimate Calorie and macronutrient intakeDiet analysisCustomize meal plans…of athletes to perform diet analysis #1…what are macronutrients?…for athletes and clients
4 Foods in the Exchange System Divided by chemical composition re:MacronutrientsSpecified portions of foods in each group are exchangeable with the other foods in that groupWhat are macronutrients? Each svg. Has about the same amt. of CHO, PRO, FAT and overall kcal; for this reason any food within the same category can be exchanged/traded for another food in that group, in the right portion size…because they have similar chemical makeups, meaning similar amounts of macronutrients; helpful in maintaining a varied diet
5 Food Groups Foods classified into 6 groups: Starch Fruit Milk VegetablesMeat/meat substitutesFatList examples of each
6 Starch Group 15 g carbohydrate 3 g protein 0-1 g fat 80 Calories Examples:½ Cup oatmeal1 Avg. slice bread½ English muffin½ Hot dog/hamburger bun½ Cup corn/peasRemind them of their maps!
7 Fruit Group 15 g carbohydrate 0 g protein 0 g fat 60 Calories Examples:1 small banana1 ¼ Cups strawberries½ Cup orange juice¾ Cup fresh pineapple
8 Milk Group 12 g carbohydrate 8 g protein 0 g fat (for non-fat milk) 90 CaloriesExamples:1 Cup non-fat milk1 Cup soy milk2/3 Cup fat-free, artificially sweetened yogurt
9 Vegetable Group 5 g carbohydrate 2 g protein 0 g fat 25 Calories Examples:½ Cup cooked spinach1 Cup baby carrots1 Cup diced tomatoes1 Cup cucumbers
10 Meat/Meat Substitutes Very lean: 35 Cal, 7g PRO, 1g FATLean: Cal, 7g PRO, 3g FATMed fat: Cal, 7g PRO, 5g FATHigh fat: 100 Cal, 7g PRO, 8g FATExamples:¼ Cup egg substitutes; white meat poultry, no skin1 oz lean cut beef (round, sirloin, loin, flank)1 egg; 1 oz ground beef, poultry w/skin, fried fish1 oz of most cheeses, sausages; peanut butter
11 Fat Group 0 g carbohydrate 0 g protein 5 g fat 45 Calories Examples: 1 tsp oil½ Tbsp peanut butter1 Tbsp reduced-fat mayo1 Tbsp cream cheese
12 Diet Prescription #1: #2: Calculate energy needs Male, 165#, runner 3000 Cal/day#2:Convert pounds into kgDivide 165# by 2.2 kg = 75 kgMultiply 165# by kg = 75 kg
13 Diet Prescription #3: Calculate g CHO, PRO, FAT ACSM & ADA CHO: PRO: 6-10 g CHO/kg BWPRO:Endurance: g PRO/kg BWPower: g PRO/kg BW
14 Diet Prescription #3 cont’d: Calculate g CHO, PRO, FAT Example: 75 kg x 6 g/kg BW = 450 g CHO = 1800 Cal75 kg x 1.4 g/kg BW = 105 g PRO = 420 Cal= 2220 Cal3000 – 2220 = 780 Cal left for FAT780 Cal/9 Cal/g FAT = 87 g FATCHO = 60%PRO = 14%FAT = 26%
15 Diet Prescription#4: Figure # of exchanges for CHO-containing food groupsFollow this order:***MilkFruitVegetable***Always begin with CHO-containing food groups
16 Diet Prescription#5: Add all of the carbohydrates you have used so far for milk, fruit, & veggie exchanges.Subtract from total g CHO.Divide by 15.This is how many starch exchanges you will have.
17 Diet Prescription#6: Add grams of protein used thus far for milk, veggie, and starch exchanges.Subtract from total grams of protein.Divide by 7.This is how many meat exchanges you are allotted.
18 Diet Prescription#7: Add grams of fat used so far from starch and meat exchanges.Subtract from total fat grams.Divide by 5.This is how many fat exchanges you will have.#8: Add Cal from each food group to double check your work.Be sure you are near your total Cal/day.
19 Calculating Exchanges: 24-Hour Recall 2 Cups cereal w/ 1 cup 2% milk2 starches and 1 milk + 1 fatTurkey & cheese sandwich and chips2 slices bread = 2 starch1 T mayo = 1 fat3 oz turkey = 3 very lean meats1 oz potato chips = 1 starch + 2 fatsPork loin, squash, dinner roll w/margarine5 oz pork loin = 5 lean meats fats½ cup squash = 1 starch1roll w/1 Tbsp lite margarine= 2 starch + 1 fat
20 Calculating Exchanges: Labels Begin with starch exchangesLook at total grams CHO1. Divide by 152. Multiply that number by 3 g protein.3. Subtract that number from total grams PRO on the label.4. Divide by 7 to get number of meat exchanges.5. Take the number you calculated from #1 and multiply it by g fat (1 g fat per each starch exchange).6. Divide that number by 5 g fat to determine fat exchanges.
