Why do you think that certain foods give people more energy than others? think about the role the digestive system plays in this process.

I am not completely sure about this, but in a case where person a has a piece of steak and vegetables, they would have more energy because thats protein and long term energy while person b who had 85 candy bars would be hyper for only a little while because starch is a short term energy source and once you come down from your sugar rush, you crash.

A. vitamin c is your answer
