The word ‘rational’ is typically used to refer to a property of a belief system that leads to increased map territory convergence, or of a planning system that leads to increased degree of goal achievement.
The question of whether or not to be vegan instead mostly looks like a question of how much moral weight to put on various classes of entities, which doesn’t seem like it’s deeply related to either of those properties. There’s probably a better adjective to use.
Unless there was an argument (which the OP is not making) about the use of resources or the insurgence of an x-risk, in which case rational would be the probably correct adjective.
