While landing on Runway 3; after touchdown which was normal; I encountered a sudden; unexpected gust of wind that swerved the aircraft to the left before I had a chance to correct with right rudder. ATIS was calling wind at 300/12; although the surface winds had been gusty all morning. The aircraft went left off the runway and came to a sudden stop in the farm field mud.The aircraft sustained damage to the prop and; as a result of the strike; required an engine teardown and inspection. I was alone and unhurt and there was no property damage. Contributing cause might have been my low blood sugar causing my slow reaction to using opposite rudder; I had had a light breakfast that morning; but had been waiting all day as maintenance work was being performed.
During the landing rollout an unexpected gust of wind struck the reporter's C210 pulling it to the left and off the runway resulting in a prop strike.
