50
Calculations
- Use similar values to multiply or divide.
| - To find percentage of calories, both numbers have to be calories.
51
Compute Grams to Calories
- Find number of grams of the nutrients.
- Multiply 4 for carbs and protein, 9 for fat.
- Answer is number of calories generated from the nutrient.
52
Find the percentage of a nutrient
- Find total number of calories for a serving size.
- Find total number of calories from fat.
- Divide calories from fat by total.
- Multiply by 100 for percentage.
53
EXAMPLE 1
- Baked beans-260 calories
- 2 g fat per serving
- Fat has 9 cal/g so 2 grams of fat multiplied by 9 equals 18 calories.
54
EXAMPLE 2
-One serving of toaster strudel has 350 calories.
-140 calories are from fat.
-What percent fat is toaster strudel?
-140/350=.4
.4x100=40%
55
EXAMPLE 3
- One cup of crabapple juice has 160 calories.
- 30 g is carbohydrates
- What percent of the calories are carbohydrate?
- 30/4=120 bc 4 cal/g in carbs
- 120/160=0.75
0. 75x100=75%
56
EXAMPLE 4
- There are 1.5 g of protein in one serving of Campbell's beef and potato soup.
- You eat two servings.
- How many grams of protein do you consume?
- 1.5x2=3
57
EXAMPLE 5
- One serving of turkey breast has 60 calories.
- There are 1.5 g of fat per serving.
- How many calories are from fat?
- 9 cal/g
- 1.5x9=13.5
58
EXAMPLE 6
- One serving of turkey breast has 60 calories.
- 13.5 calories are fat
- What percentage of the turkey breast is fat?
- 13.5/60=0.225
- 0.225x100=22.5%
59
EXAMPLE 7
- One cup of instant breakfast has 250 calories.
- 30 g are carbohydrate.
- What percentage of the Instant Breakfast is carbohydrate?
- 4 cal/g
- 4x30=120
- 120/250=0.48
- 0.48x100=48%
