Given the details in the table, we can solve the questions using the following steps:
Part A: Percent daily value of fat calories for each of the four foods. Recall that there are 9 calories per gram of fat.
For one bowl of cereal and milk:
For One peanut butter and Jelly Sandwich:
For One Waffle:
For One granola bar:
PART B: Based on the percent daily values of fat calories gotten for the four foods above, it can be said that the least healthy food is One Waffle with 48% while the most healthy food is One Bowl of Cereal and Milk with 12%.
PART C: The most healthy food was One Bowl of Cereal and Milk while the least healthy is One Waffle because The Institute of Medicine and the American Heart Association recommend a total fat intake of 25-35 percent of calories. Hence, the higher the food goes above the 35% mark, the less healthy the food becomes.
