Superpowers usually have a lot of implications that we don’t see on screen. While properties like My Hero Academia dive deep into these implications, superhero universes like the MCU tend to shy away from them. For example, Captain America has a metabolism that is four times faster than the average human being, as revealed in Captain America: The First Avenger. While it keeps Captain America from getting drunk, it also has certain other implications for his body.
Chris Evans’ Captain America, who has been an important part of the Marvel Cinematic Universe, having been part of some of its biggest conflicts, might have been fighting his own body all along as well. As this Marvel theory suggests, the super soldier serum might have given Steve Rogers a host of powers but also created a particularly strong gastric problem for The First Avenger with its “gift” of a faster metabolism.
Captain America probably had to spend a lot of time in the washroom
Given that Steve Rogers has a faster metabolism than the average human being, it means that he cannot get drunk. It also means that the massive amounts of food he must consume get digested pretty quickly. This implies that the Star Spangled Man with a Plan probably has a very rigorous and recurring bathroom schedule, given the mass of food that has to exit his body and the amount of food he would have to eat to maintain his powers.
This implies that Chris Evans‘ Captain America probably had to hold it in during some key moments in the MCU, be it during the first Avengers movie when the team was “posing up a storm” standing over Loki, or when he was going through emotional turmoil while fighting The Winter Soldier.
However, given that superhero universes are often a little more advanced than the present that they depict on screen, Steve Rogers may have already been given a solution by the great minds of the 21st Century, like Tony Stark or Hank Pym.
Caloric food probably saved Captain America some bathroom trips
While it would be necessary for Captain America to have a lot of food just to maintain his physicality and his abilities, Tony Stark could come up with a host of solutions for Steve’s food-related problems. Stark could help develop some sort of super-food that allows Cap to get his required number of calories, without having to deal with enormous quantities of food that result in him running to the washroom every 30 minutes.
A similar problem cropped up for another hero, albeit in a different universe. The Flash also has a severely increased metabolism, causing him to consume a lot of food. However, Cisco Ramon did develop some high-caloric protein bars for the Scarlet Speedster in CW’s The Flash, making it easier for Barry Allen to deal with his caloric requirements, without having to consume more food than he could manage.
