Well I know how the topic sound, but it has to do with civil war lol. I remember a while ago when I watched a history channel program on civil war, it talked about a specific campaign that lasted a few days on a hill after heavy rain. Both sides were exhausted in the fighting, because the wet muddy ground, and the slope of the hill. However, it said the southern soldiers were more exhausted than the union soldiers because of the diet. It mentioned that the Union soldiers were having beef and bread as meals, while the Confederation soldiers were having pork and corn. Does beef and bread really give that much more energy to humans compare to pork and corn?
