Everyone must eat. Settled peoples get the majority of their sustenance from crops they grow.
Twelve bushels of grain and pulse (supplemented by animal products and foraged or garden vegetables) sustains a working or pregnant adult for a year. Ten bushels sustains a child or idler.
On up to two fewer bushels per year, or without supplemental foods, one must make a DC 15 roll or lose a random month of work to illness. For every six points the roll fails by, another month is lost.
