I agree with the answer above and would like to add on to it. When looking at nutrition labels you should be looking at what ingredients was used to make the food, including the chemical compositions. For an example, some people are allergic to peanut butter, therefore it is their responsibility to check the label so that they know what company made it and the ingredients. Also remember to check the expiring date :D
How badly the person is injured (how deep the cut or how bad the tear) and their body type.
Conditioning! This has to be it the others seem unrelated. Terribly worded question.
