It isn't that it is hard, it's that it is a thing that has to be done, and so your brain cycles + interruptions are dedicated to these things.
Cooking is generally taken care of by parents, which means ancillary things like grocery shopping are too. You don't even have to dedicate brainwidth to "what groceries do we need to buy". There are so many tiny interruptions and bureaucratic overhead that keeps the brain slightly stressed as an adult that simply don't exist as a child, it is marvelous.
