Plutarch

Plutarch — philosopher, traveler, and observer of human nature — was born 9 years
after the death of Celsus. Although untrained in medicine, Plutarch wrote extensively
on food and dietary topics and proposed several dietary recommendations:

4. Milk ought not be used as a beverage but as a food [one that] possesses
solid and nourishing power; wine is the most beneficial of beverages. In
the course of the daily routine [drink] two or three glasses of water.
5. In regard to food and drink it is expedient to note what kinds are whole-
some rather than what are pleasant, and to be better acquainted with those
that are good in the stomach rather than in the mouth, and those that do
not disturb the digestion rather than those that greatly tickle the palate.138
Plutarch suggested that food should be simple. He wrote that moderation kept
appetite in check and discouraged eating fancy culinary creations.
