Is it possible to digest all your food at the same time?
It depend on the amount of food. If you simply swallow, lets
say, a small strawberry, without chewing, and call that all your
food, then yes, the entire strawberry would be digested at the same
rate. However, if you were eating, lets say, a peice of chicken,
and you were taking the time to chew and swallow each bite, then
each of these swallows would be slightly off. For example, when you
are chewing one peice, another might be in your esophagous, or in
your stomach.
