Human use edit

One of the Maya peoples, the Lacandon people, now Mexico's native peoples from state Chiapas, use Pachychilus indiorum, known locally as "t’unu", as a type of protein supplement to their diet when animal protein is unavailable.[7] In addition, the shells from this "chuti" snail have great nutritional value, as they provide calcium and slaked lime when burnt. They are often preferred as a lime source over local limestone or other freshwater snail species for their purity as an alkali. The slaked lime is added to maize during the process of making maize dough for tortillas, pozole, and other foods. Slaked lime allows the release of amino acids such as tryptophan and lysine and the vitamin niacin, which would otherwise be unavailable from the maize (unable to be metabolized) if the lime were not added.[7]
