# IS THE FOOD I AM EATING REALLY FAT FREE

by Kari

(MIAMI, F.L.)

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 grateful to have come across this web page, I have never seen or had help like this, never, ever. Thank you.

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.
