Reconstructions of the diets of late-sixteenth-cent Apalachee Indians have been based on two sources: accounts by Europeans and food remains at archaeological sites. Some written records depict little farming at the time; others say that the Apalachee relied heavily on agriculture, particularly on corn. Archaeological records are also inconclusive. Plant remains do not always survive well-in coastal regions they are particularly vulnerable to the destructive effects of moisture and acidic soils. Nevertheless, analysis of such evidence confirms that the Apalachee ate both wild and domesticated plant species. But their use of corn is unclear: although excavations have revealed kernels and cobs from sixteenth-century sites, the relative importance of this grain in the Apalachee diet is not known.
