Is food digested in the order it is consumed? Or digested like freeway traffic moves, with some food overtaking slower to digest food?

And how does the body decide, if it moves like traffic? Does  everyone have the same 'speed limits' or does it vary per individual?

Different organs are responsible for digesting different types of foods. The pancreas, liver and stomach produce and distribute the vast majority of chemicals required to break down the foods, and they are all broken down and absorbed into the digestive tract where they will be sent to the cells in different parts of the body to be built back up into other molecules. It is a continuous process where certain things do digest faster but the physics side of things like the amount or concentrations of foods determines the order they are digested. Basically, if you consume a ton of sugar and a little bit of fat, the higher concentration of sugar will make the amount of energy needed to break down sugars less meaning the high concentrations tend to break down first since they require less activation energy. So, depending on how much you eat combined with what it is determines what breaks down first.
