IS THE FOOD I AM EATING REALLY FAT FREE

by Kari
(MIAMI, F.L.)

Gather three of your favorite packaged foods; perhaps one from each: breakfast, lunch and dinner. Use the model explained in the “Are You Sure It’s Fat Free?”

( The reason that a 97% fat free food is too good to be true is that the food industry bases its figures on the weight of the product and not the calories the product contains. For example, suppose a 10-ounce serving of a food contains 240 calories, and the label states that it contains 9 grams of fat. The food industry then converts 10 ounces to grams by multiplying each ounce by 29 grams; hence, the total weight of the product is 290 grams, and if there are 9 grams of fat, the percentage of fat is
9
290 × 100% = 3.1%

The procedure used by the food industry is misleading. The correct way to calculate the fat content is to multiply the number of grams of fat by 9 to get the calories. (Each gram of fat is converted to 9 calories.) In this case, 9 × 9 = 81 calories. Next, divide the fat calories by the total calories and multiply by 100% to get the percentage of calories derived from fat. In this case, the label stated that a 10-ounce serving contained a total of 240 calories.

81
240 × 100% = 33.75%

Hence, 33.75% of the calories come from fat, not 3% as suggested )

to analyze, through the mathematical formula explained, the fat content and protein content from your foods. To analyze the protein content use 4 calories per gram of protein, rather than the 9 calories for grams of fat.


1) Pillsbury Toaster Strudel, Strawberry
Serving size- 1 pastry (54g)
Calories for single serving-190
Fat content- 8 grams
Protein- 3 grams

2) Raisin Bran Crunch
Serving size- 1 Cup (53g)
Calories for a single serving-190
Fat Content- 1 gram
Protein- 3 grams

3) Activia Yogurt, Vanilla
Serving Size- 1 Container (4 oz)
Calories for a single serving-110
Fat Content-2 grams
Protein-5 grams

I am not sure how to complete this practice question, and I would like learn the steps. I am beginning a beginners math class (in college) next month, and I am reviewing mt college text early and just want to be prepared; no rush. This is not an actual assignment, rather something I am choosing to do on my own, for my own benefits. I want to be prepared with all of the steps!! I am greatful to have come across this web page, I have never seen or had hep like this, never, ever. Thank you.

starstarstarstarstar 		i am the same person who submitted the question
by: kari

I am not sure how to write it, as it states to write the the answer (or equation) the same way as I indicated or stated in my intiol question when I reached out for help, but this is what I do understand, from directions.

1) Pillsbury Toaster Strudel, Strawberry
Serving size- 1 pastry (54g)
Calories for single serving-190
Fat content- 8 grams
Protein- 3 grams

8 * 9 = 72
* 190 = ?
3 * 4 = 12

total 84 grams

3g of protein * 4 = 12 additinal calories (not sure if I am correct. But would the total be
1,7 22 calories ??? or what steps would I follow? Please help me, so I know how to do or show the correct equation.

2) Raisin Bran Crunch
Serving size- 1 Cup (53g)
Calories for a single serving-190
Fat Content- 1 gram
Protein- 3 grams

190 * 9 = 1,710 calories
1,722 * 100% =
3g protein * 4 = 12 calories


I am not sure how to get or divide by 100% to get the actual percentage of fat in each meal. please help wih detailed help (for this meal and the other 2 meals below). I am not sure I calculated the above numbers right, but I think what I got so far is correct, like I said, just need step by step help and I appreciate your help (whoever you are).

3) Activia Yogurt, Vanilla
Serving Size- 1 Container (4 oz)
Calories for a single serving-110
Fat Content-2 grams
Protein-5 grams

110 * 9 = 990
998 * 100 =???
2 * 4 = 8

3) Activia Yogurt, Vanilla : Calculations
Serving Size- 1 Container (4 oz) , or 116 grams
Calories for a single serving-110
Fat Content-2 grams
Protein-5 grams

FOOD INDUSTRY FIGURES ? misleading: the food industry BASES its FIGURES on the WEIGHT of the product and NOT the CALORIES the product contains:

1 serving contains 4 oz. 4 oz x 29 grams per ounce = 116 grams per serving

(2 grams of fat by weight ÷ 116 grams total weight of 1 serving) × 100%

= 1.72% FAT CONTENT BY WEIGHT




ACTUAL FAT CONTENT: BASED on CALORY CONTENT (not weight):


Calories from Fat content: (2 grams of fat)*(9 calories per gram of fat) = 18 calories

% Calories from Fat:

[(18 calories)/(110 calories)]*100

= 16.36% FAT CONTENT based upon total calories from 1 serving


Calories from Protein content: (5 grams of protein)*(4 calories per gram of protein) = 20 calories

% Calories from Protein:

[(20 calories)/(110 calories)]*100

= 18.18% PROTEIN CONTENT based upon total calories from 1 serving


Fat Summary - Activia Yogurt, Vanilla

16.36% of the calories come from fat (over 9.5 times the Industry Figure of 1.72%)

18.18% of the calories come from protein




Thanks for writing.

Answer:


1) Pillsbury Toaster Strudel, Strawberry : Calculations
Serving size- 1 pastry (54g)
Calories for single serving-190
Fat content- 8 grams
Protein- 3 grams

FOOD INDUSTRY FIGURES ? misleading: the food industry BASES its FIGURES on the WEIGHT of the product and NOT the CALORIES the product contains:

(8 grams of fat by weight ÷ 54 grams total weight of 1 serving) × 100%

= 14.8% FAT CONTENT BY WEIGHT


ACTUAL FAT CONTENT: BASED on CALORY CONTENT (not weight):

Calories from Fat content: (8 grams of fat)*(9 calories per gram of fat) = 72 calories

% of Total Calories from Fat:

[(72 calories)/(190 calories)]*100

= 37.9% FAT CONTENT based upon total calories from 1 serving



Calories from Protein content: (3 grams of protein)*(4 calories per gram of protein) = 12 calories

% Calories from Protein:

[(12 calories)/(190 calories)]*100

= 6.32% PROTEIN CONTENT based upon total calories from 1 serving




Fat Summary - Pillsbury Toaster Strudel, Strawberry

37.9% of the calories come from fat (over 2.5 times the Industry Figure of 14.8%)

6.3% of the calories come from protein



2) Raisin Bran Crunch : Calculations
Serving size- 1 Cup (53g)
Calories for a single serving-190
Fat Content- 1 gram
Protein- 3 grams

FOOD INDUSTRY FIGURES ? misleading: the food industry BASES its FIGURES on the WEIGHT of the product and NOT the CALORIES the product contains:

(1 grams of fat by weight ÷ 53 grams total weight of pastry) × 100%

= 1.9% FAT CONTENT BY WEIGHT


ACTUAL FAT CONTENT: BASED on CALORY CONTENT (not weight):

Calories from Fat content: (1 gram of fat)*(9 calories per gram of fat) = 9 calories

% Calories from Fat:

[(9 calories)/(190 calories)]*100

= 4.74% FAT CONTENT based upon total calories from 1 serving


Calories from Protein content: (3 grams of protein)*(4 calories per gram of protein) = 12 calories

% Calories from Protein: [(12 calories)/(190 calories)]*100

= 6.32% PROTEIN CONTENT based upon total calories from 1 serving



Fat Summary - Raisin Bran Crunch

4.74% of the calories come from fat (just under 2.5 times the Industry Figure of 1.9%)

6.3% of the calories come from protein
