The Exchange System:
What is it?
▪ Food classification method
▪ Created for diabetics by ADA & ADA
▪ Track Calories, CHO’s, PRO, FAT
▪ Healthy way of eating

Foods in the Exchange
System
 Divided by chemical composition re:
 Macronutrients
 Specified portions of foods in each group are
exchangeable with the other foods in that group
 So in the fruit list, ½ cup orange juice can be
exchanged for a cup of strawberries without
increasing calories and carb grams.

FOOD GROUPS:
Foods classified into 7 groups:
 Vegetable
 Fruit
 Starch
 Milk
 Meat/meat substitutes
 Fat
 Sugar

Diet Prescription
#1:
 Calculate energy needs
 Male, 75 kg, runner
 3000 Cal/day
Diet Prescription
16
▪ Calculate g CHO, PRO, FAT
▪ ACSM & ADA
 CHO:
 6-10 g CHO/kg BW
 PRO:
▫ Endurance: 1.2 – 1.4 g PRO/kg BW
▫ Power: 1.6- 1.7 g PRO/kg BW
#1:
17
Calculate g CHO, PRO, FAT
Example:
▪ 75 kg x 6 g/kg BW = 450 g CHO = 1800 Cal
▪ 75 kg x 1.4 g/kg BW = 105 g PRO = 420 Cal
▪ 1800+420 = 2220 Cal
▪ 3000 – 2220 = 780 Cal left for FAT
▪ 780 Cal FAT = 87 g FAT

Diet Prescription
#2:
Figure no of exchanges for CHO-containing food groups
Follow this order:**
• Milk
• Fruit
• Vegetable
***Always begin with
CHO-containing food
groups
19
Diet Prescription
#3: Add all of the carbohydrates you have used so far
for milk, fruit, & veggie exchanges.
 Subtract from total g CHO.
 Divide by 23.
 This is how many starch exchanges you will have.
20
Diet Prescription
#4: Add grams of protein used thus far for milk, veggie, &
starch exchanges. Subtract from total grams of protein.
 Subtract from total grams of protein.
 Divide by 8.
 This is how many meat exchanges you are allotted.
21
#5: Add grams of protein used thus far for milk, veggie, and
starch exchanges. Subtract from total grams of protein.
 Subtract from total grams of protein.
 Divide by 5.
 This is how many fat exchanges you will have.
#6: Add Cal from each food group to double check your work.
 Be sure you are near your total Cal/day.

Carbohydrate partial sum
= 9 g + 50 g + 12 g +15 g = 86 g
No. of Rice exchanges:
245 g (prescribed carbohydrate)
-86 g (partial sum carbohydrate)
------------------------------------
=159 g
159 g ÷ 23 g
= 6.91 or 7 Rice exchanges

-25 g (protein partial sum)
------------------------------------
=35 g
35 g ÷ 8 g
= 3.75 or 4 Meat exchanges
