Crops can blight, animals can get diseases. I don't know much about hydroponics but I know that bacteria are a concern. What food source is the most reliable, the least likely to produce less food than expected?

One possibility is breadfruit. We, realistically, can't depend on one though. Even the most robust staple food will still have some sort of vulnerability so it will always be of benefits to have several.
