What to know about Scurvy's skeletal fingerprint found in California's Late Holocene archaeological sites

A study published in the International Journal of Osteoarchaeology examines skeletal remains from Late Holocene sites in California to identify evidence of scurvy. The research suggests that infants were more frequently affected by vitamin C deficiency, potentially due to maternal dietary restrictions and the nutritional demands of pregnancy and breastfeeding.

Why it matters

The change observed shows the cascading impacts of dietary practices on skeletal development, including in infants, which may have been affected during pregnancy or breastfeeding, highlighting the largely invisible impacts of pregnancy in the archaeological…

Common ground

Scurvy in Late Holocene Californians Scurvy is a nutritional deficiency that develops within one to three months of a deficiency (<10mg/day) of vitamin C intake, despite California being rich in native vitamin-C-rich foods.
