Its easy for us to go obtain and find the strike away Fat-Free and be capacitance with the food we are eating, but is it really dilate free? The food labels can misleads us by calculating the fat content in packaged food solely on its weight. When in reality the fat content has more to do with the calorie value of each(prenominal) food item instead of its weight. So in regularize to properly calculate fat we do to base it off calories in order to hold out the fat and protein content. After end week twos reading Are You Sure Its Fat Free? on page 286 of mathematics in Our World. I was able to put this to the test. I collected three of my favorite packaged foods and was then able to analyze, through and through the mathematical decree explained, the fat and protein content from them. The best upside is to analyze the protein content by using 4 calories per deoxyguanosine monophosphate of protein, rather than the 9 calories for gibibytes of fat. This little bit of knowledge was able to be a real eye opener, especially when shopping for packaged foods for the household.
The breakfast food I chose was oatmeal since it is a popular breakfast meal. You will see for each formula the pattern repeats for grams of fat and grams of protein. For each breakfast, lunch, and dinner item you have to calculate each gram of fat or protein into calories.
believe 1 gram of fat has 9 calories, while 1 gram of protein has 4 calories. You then take that number and dissever it by the total Calories and multiply by 100 % to get the percent age of calories derived from fat (Bluman, A. G. 2005, page 286).
Breakfast: supporter Oats (Oatmeal) (Single serving ½ cup = 40 grams)
Calories in a sensation serving = 150
Fat content is 3 gram
1 gram of fat has 9 calories
3 grams of fat = 3 * 9 = 27 calories.
The fat content is (27/150) * 100 = 18 %
Protein content is 5 grams
1 grams of protein has 4 calories
5 grams of protein = 5*4 = 20 calories
The protein content is (20/150) * 100 = 13.3%
