Scurvy Evidence Discovered in Late Holocene Californian Human Remains

Archaeologists reported on May 11, 2026 the identification of skeletal lesions consistent with scurvy in human remains recovered from several Late Holocene sites across California, dating from 500 BCE to 1834 CE. The findings, detailed in the *International Journal of Osteoarchaeology*, illuminate the nutritional stresses faced by indigenous populations prior to and during early European contact.

Scurvy, a disease caused by vitamin C deficiency, is rare in the archaeological record due to the rapid degradation of soft tissues. However, characteristic bone changes—particularly porous lesions on the cortical surfaces of ribs and femurs—provide a diagnostic marker when present.

Lead author Dr. Elena Martinez of the University of California, Santa Barbara, described the discovery of subperiosteal hemorrhages and porotic hyperostosis in ten individuals, nine of whom were sub‑adults. “These lesions suggest chronic dietary shortages, possibly linked to the seasonal scarcity of fresh plant foods or disruptions caused by trade and colonization,” she noted. The study also cross‑referenced isotopic analyses indicating limited consumption of vitamin‑C‑rich foods during certain periods.

The research contributes to broader discussions on how environmental changes and sociopolitical factors affected health in pre‑colonial North America. Dr. James Liu, a bioarchaeologist unaffiliated with the study, remarked that “evidence of scurvy adds a new dimension to our understanding of resilience and vulnerability among coastal and inland groups.” The findings also raise questions about the role of trade networks in mitigating nutritional deficiencies.

The team plans to extend their analysis to additional sites across the western United States, employing micro‑CT scanning to identify subtler markers of vitamin deficiencies. Further interdisciplinary work with paleobotanists could reconstruct seasonal diet patterns. The study underscores the importance of integrating osteological and isotopic data to reconstruct past human health trajectories.
