Generally, injuries that occur during lunch breaks aren’t considered work-related. For example, you probably can’t claim workers’ comp for twisting your leg while going out to a coffee shop to get your breakfast. However, if you were picking up food for a work-related venue, that might be covered.
That said, if you were eating on the company’s premises and were injured in the cafeteria, the injury will often be considered work-related and be covered under workers’ compensation. However, if you were doing something that you weren’t allowed to do or was outside the normal activities on-premises, that you probably won’t be covered. For example, if you decided to do a half-hour workout routine during your break and fractured your wrist doing push-ups, you probably won’t be able to collect workers’ comp.
