Unlearned specific appetite for protein
Abstract
Appetite for most protein appears to be unlearned. Protein-depleted rats, in the first half hour of a test, chose a significantly larger proportion of soybean, gluten, zein, fibrin, yeast torula and ovalbumin than protein replete controls, but not of casein or lactalbumin. There had been no opportunity to learn such dietary preference before the test. The preference for the protein in protein-depleted rats manifested itself significantly from the first minute, and also in females in which protein need was induced by pregnancy rather than a diet different from the controls.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
