A trail ration is one day worth of food. Ten days of trail rations are part of the standard adventurer's kit. * Price: 5 sp, 5 gp for 10 days. * Weight: 1 lb., 10 lb for 10 days. The trail ration has no official description, although it obviously stops the effect of starvation. Under standard rules, one day of rations is sufficient to reset the starvation counter. Pathfinder described the ration as a form of bland food, although it can remain unspoiled for months as long as the rations are kept dry. [d20pfsrd.com]
