Sardinian dietary analysis for longevity: a review of the literature
Bibliographic record
Abstract
Abstract Sardinia is one of the five Longevity Blue Zones (LBZs) in the world. Compared to other LBZs, the percentage of male centenarians in Sardinia is much higher. Due to the island’s isolation, the genetic traits of Sardinian people have shown that they are direct descendants of their Nuragic ancestors from the Neolithic era. To survive during times of food scarcity, many “famine foods” are created; acorn bread containing clay, cheese ripened in goat abomasum, and soft cheese with worms are examples of these uncommon foods. Although considered food taboo by the outside world, they are cherished as cultural heritage and local delicacy. Studies have shown that Sardinian longevity is closely related to their special famine foods. They are not only nutritious; the production of these foods resulted in low stress and increased lifespan. Moreover, local food production practices have resulted in a strong cultural bond and helped the Sardinian people to survive cultural erosion from industrialization and modernization.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
