The Esquimaux or Greenlander finds his most desirable meal in a lump of raw blubber, the most condensed form of carbonaceous food being required to preserve life.

It is not a perverted taste, but the highest instinct; for in that cruel cold the body must furnish the food on which the keen air draws, and the lamp of life there has a very literal supply.
Take now the other extreme of temperature,--the East Indies, China, Africa, and part even of the West Indies and America,--and you find rice the universal food.

There is very little call, as you may judge, for heat-producers, but rather for flesh-formers; and starch and sugar both fulfill this end, the rice being chiefly starch, which turns into sugar under the action of the saliva.

Add a little melted butter, the East Indian _ghee_, or olive-oil used in the West Indies instead, and we have all the elements necessary for life under those conditions.
A few degrees northward, and the same rice is mingled with bits of fish or meat, as in the Turkish _pilau_, a dish of rice to which mutton or poultry is added.
The wandering Arab finds in his few dates, and handful of parched wheat or maize, the sugar and starch holding all the heat required, while his draught of mare's or camel's milk, and his occasional _pilau_ of mutton, give him the various elements which seem sufficient to make him the model of endurance, blitheness, and muscular power.

So the Turkish burden-bearers who pick up a two-hundred-pound bag of coffee as one picks up a pebble, use much the same diet, though adding melons and cucumbers, which are eaten as we eat apples.
The noticeable point in the Italian dietary is the universal and profuse use of macaroni.
