Talmudic Guidance on Diet and Regimen
The Babylonian Talmud evinces a certain interest in the topic of diet and regimen. This interest was probably brought to Babylonia from Palestine, since indigenous Babylonian medicine did not engage in preventive medicine or offer advice on how to stay healthy. Interest in diet and regimen was a specialty of both Hippocratic and later Greco-Roman medicine.
Rabbinic recipes that prescribe ordinary foodstuffs as materia medica are not advising patients to avoid illness but rather are suggesting treatments for (likely acute) diseases. Aramaic texts with Hebrew glosses usually suggest alternative Babylonian ingredient substitutes, because the plants found in Babylonia differed from those available in Palestine.
