Ohlone Diet at Mission Santa Clara: Beef, Malnutrition & Disease

The Ohlone (Costanoan) peoples of the San Francisco Bay Area experienced catastrophic dietary disruption at Mission Santa Clara de Asís (founded 1777).

Traditional Diet (Pre-Mission)

• Acorns (multiple oak species) – staple, leached, ground to flour
• Seeds: chia, redmaid, tarweed, grass seeds
• Game: deer, elk, pronghorn, rabbit, waterfowl
• Seafood: mussels, clams, oysters, salmon, sturgeon, surf fish
• Plants: soaproot, brodiaea bulbs, berries, greens
• Managed landscape: cultural burning for seed/forage production

Mission Diet (Documented)

• Beef (cattle): Primary protein for neophyte (baptized) laborers. Cattle herds = mission wealth.
• Atolé / Pinole: Ground roasted grain (wheat, barley, corn) porridge—daily staple.
• Pozole: Hominy stew with meat/fat.
• Limited: Vegetables, fruit, dairy. No acorns, no traditional foraging access.

Health Consequences

• Malnutrition: Protein-calorie deficiency, niacin (pellagra), vitamin C (scurvy).
• Disease: Measles, smallpox, dysentery, syphilis, tuberculosis. No immunity.
• Demographic collapse: Bay Area Ohlone dropped from ~15,000 (1770) to <2,000 (1832).

Nuance: "Ranch Hands" Context

The source notes Ohlone who worked as vaqueros (cowboys) on mission ranchos received beef rations. This was a privileged minority. Most neophytes ate atolé in crowded, unsanitary conditions.

Legacy

Today, Ohlone descendants (Muwekma, Amah Mutsun, Costanoan Rumsen) revitalize traditional foods: acorn mush, native seed cakes, tule boat building. Food sovereignty = cultural survival.
