All places I worked so far in sweden had mandatory lunchbreaks. From 30 minutes in care-jobs to 1 hour in IT. After 5 hours your employer is required to give you a longer break where you are allowed to leave your job for lunch or whatever. Many eat out but it's also common to bring a lunchbox with rests from yesterdays dinner. A lunch is usually around 10 euro at a restaurant so many eat lunchboxes to save money and/or live healthier.
