Capable of being digested; able to be broken down by the digestive system.
From 'digest' plus the adjective-forming suffix '-ible' (from Latin -ibilis). The suffix indicates possibility or capability, so 'digestible' literally means 'able to be digested'.
There's a reason doctors tell people with upset stomachs to eat bland, easily digestible foods—your gut doesn't have to work as hard, giving it time to heal and recover.
