It is a general rule, that the stronger each kind is, so much the less easily it is concocted; but when once concocted, it nourishes more. Wherefore the nature of the food must be determined by the degree of one’s strength; and the quantity proportioned to the kind. Upon this account weak men must make use of the weakest things; a middle kind best supports those, that are moderately strong; and the most substantial is fittest for the robust. Lastly, A person may take a greater quantity of what is lighter: but in what is most substantial, he ought to moderate his appetite.
CHAP. XIX. GENERAL PROPERTIES OF DIFFERENT FOODS.
And these above-mentioned are not the only distinctions; but some things afford good juices, others bad, which two kinds the Greeks term euchyma and cacochyma[ AY ]; some are mild, others acrid; some generate in us a thicker phlegm, others a more fluid; some agree with the stomach, others not; likewise some produce flatulencies, others have not that property; some heat, others cool; some readily turn sour in the stomach, others are not easily corrupted there; some open the belly, others bind it; some promote urine, others retard it; some are soporiferous, others excite the senses. Now all these must be known for this reason, that different things are proper in different constitutions or states of health.
CHAP. XX. OF THINGS CONTAINING GOOD JUICES.
Good juices are afforded by wheat, siligo, alica, rice, starch[(47)], tragum[(48)], milk, soft cheese, all venison, all birds of the middle class; of the larger kind also, those that we mentioned above; the middle kind betwixt tender and hard fishes, as the mullus, and lupus; pot-herbs, lettuce, nettle, mallows, cucumber, gourd, purslane, snails, dates; any of the apple kind, that are neither bitter, nor acid; wine sweet or mild, passum, defrutum, olives, or any of this fruit preserved in either of the two last mentioned liquors; the wombs[(49)], cheeks, and legs of hogs, all fat flesh, and glutinous, all livers, and a sorbile egg.
