The point you make is an important distinction. It's really effortless to put down 44oz of soda but very hard to eat the sugar equivalent of ~6lbs of carrots (even if you are juicing them 6lbs is a lot of carrot juice).
There's an age at which drinking a sugary soda becomes difficult...
Related, it was recently discovered that there is a limit to how much sugar you can (comfortably) consume, unless you are a child. In children there is no limit.
