The needs of the human body can be grouped into three major categories:

a) Communication,

b) Intake and Elimination, and

c) Protection and Survival.

 

Explain which major body systems fall in to each of these categories as well as how the systems contribute to their particular category.

Step 6

What did you learn? Are you making any changes based on the info? Will you eat more/less/no more of the food?

 

Note: fiber, a subcategory of carbohydrates, is a substance that may yield between 0 to 2 kcals/g, depending on the type of fiber in the food, microflora activity, and GI transit time. As most food labels currently do not distinguish between insoluble and soluble fiber, asking students to calculate an EXACT value would be ludicrous. As such, understand that this assignment is to provide an appropriate approximation based on the information provided, and students will not be asked to calculate fiber (for those that wish to know, understand that you would subtract the grams of fiber from the total grams of carbohydrates before multiplying by its kcal value [and this is only if the fiber is totally "unusable"] to get a more accurate number of total kcals from carbohydrates).

 

For students that wish to delve deeper and understand the disparity in caloric values, further investigation into topics far beyond the level of this class would be required, such as methods of measurement, types of transporters in the gut, conflicting and diminishing absorption rates, etc. In short, do not crack your head on this assignment trying to understand WHY there may be such a disparity between the food label and what you calculated, but rather, simply understand that there is typically a disparity, and that it does play a role in the current paradigm of energy balance in the body.
