Learning Objectives
• Expand base knowledge about foods and the impact on blood sugar levels
• Learn new tips on how to better estimate foods impact on blood sugar levels and how to best cover these foods with insulin
• Increase awareness of foods impact on glucose

Macronutrients
Protein = Glucose neutral when eaten in moderate amounts (3 oz.. or deck of cards)
Carbohydrate = all but fiber is converted to glucose
Fat = does not raise blood sugar but when eaten with carbs it slows the digestion

Macronutrient Conversion to Blood Glucose

Carbohydrate
![Page 6: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/6.jpg)
![Page 7: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/7.jpg)
![Page 8: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/8.jpg)
Multiply the grams of protein by 0.6
7 grams of protein per oz..
Example 8 oz.. steak (two decks of cards)
8 x 7 = 56 grams of protein
56 grams x 0.6 = 34
Remember meat usually shrinks by 30% or so… if you order a 12 oz. steak it is approximately 8 oz meat
Protein

FAT
![Page 10: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/10.jpg)
Multiply grams of fat by 0.1 20 grams x 0.1 = 2
BIG MAC 45 g carbohydrate, 25 g protein, and 29g fat totaling 540 calories
25 x 0.6 = 15 gm for protein
29 x 0.1 = 3 gm for fat
45 + 15 + 3 = 63 gm
To Calculate Insulin Needed for Fat

Measured the effect of chewing on blood glucose
response to four different carbohydrate foods.
Apple
Potato
Rice
Potato
Chewed food for 15 seconds or swallowed whole
Don’t chew your food…

Reasons why…
Reduction of particle size enhances delivery of food from the stomach to the small intestine
Larger surface area increases access to pancreatic enzymes
Enhancement of salivation associated with chewing increases digestion of food in the mouth and stomach

Percentage of carbohydrate present in a food
All are equal to 12 grams of carbohydrate
224 gm of milk
160 gm of watermelon
14 gm graham crackers (2 squares)
12 gm sugar (1 tbsp)
Please note it is best to do a volume measure of pasta due to the cooking time and water content.

The amount of carbohydrate in 1 gm of the specific
food
Weigh food in grams
Find the carb factor
Mulitply foods weight in grams by the carb factor
1 oz. equals 28 grams in weight
Example: 150 gram banana (carb factor .2)
150 x .2 = 30 gm carb

GLYCEMIC INDEX
The impact 50 gm of carb (fiber is not included) from a food has on blood glucose as compared to 50 gm of carb from glucose (GI 100)
How fast and how high
Nutrient content and preparation vary GI
Higher fiber = lower GI
More refined = higher GI
![Page 19: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/19.jpg)
GI Classifications
Classification GI Range Examples
Low GI 55 or less Most fruits and
vegetables,
legumes, nuts
Medium GI 56 to 69 Whole wheat
foods, sweet
potato
High GI 70 and above Refined grains,
rice, cereal
![Page 20: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/20.jpg)
Food number that estimates how much the food will
raise blood glucose after eating it.
Accounts for how much carbohydrate is in the food.
1 unit glycemic load equals the effect of consuming 1 gm of glucose
Grams of available carb x foods GI /100
Glycemic Load
![Page 21: Challenging Food Situations](https://reader034.vdocument.in/reader034/viewer/2022042701/55a73b151a28abdb258b45f1/html5/thumbnails/21.jpg)
High GI food but when we consume it we do not eat
a lot of carbohydrate from it
15 gms x 72 / 100 = 10.8
Watermelon
