I hear convenient store bentos can be pretty legit. Living off them is less of a health crisis and more just kinda sad
Yes and no. Can they be eaten as part of a balanced diet? Yes.
But eating only them? That's BAAAD news.
Japanese convenience store bentos are loaded with carbs, sodium / MSG, and other additives in HUGE amounts.
Sure, people might believe they're healthy because they're made with "fresh" ingredients, which, for the most part, they are, and people traveling (especially influencers) make a huge deal about them. But overall, there's a reason why, every time in Japanese media, they want to portray someone as unhealthy, they're eating convenience store bentos.
All the Japanese people I know avoid them like the plague, lol, except when they have a craving from time to time.
