83. And Galen, when we were just about to lay hands on the loaves, said--We will not begin supper until you have heard what the sons of the Asclepiadæ have said about loaves, and cheesecakes, and meal, and flour. Diphilus the Siphnian, in his treatise on What is Wholesome to be eaten by People in Health and by Invalids, says, "Loaves made of wheat are by far more nutritious and by far more digestible than those made of barley, and are in every respect superior to them; and the next best are those which are made of similago; and next to those come the loaves made of sifted flour, and next to them those called syncomisti, which are made of unsifted meal;--for these appear to be more nutritious." But Philistion the Locrian says "that the loaves made of similago are superior to those made of groats, as far as their strengthening properties go; and next to them he ranks loaves made of groats, then those made of sifted flour. But the rolls made of bran give a much less wholesome juice, and are by far less nutritious. And all bread is more digestible when eaten hot than cold, and it is also more digestible then, and affords a pleasanter and more wholesome juice; nevertheless, hot bread is apt to cause flatulence, though it is not the less digestible for that; while cold bread is filling and indigestible. But bread which is very stale and cold is less nutritious, and is apt to cause constipation of the bowels, and affords a very unpleasant juice. The bread called encryphiasis is heavy and difficult of digestion, because it is not baked in an equal manner; but that which is called ipnites and caminites is indigestible and apt to disagree with people. That called escharites, and that which is fried, is more easily secreted because of the admixture of oil in it, but is not so good for the stomach, on account of the smell which there is about it. But the bread called 'the clibanites' has every possible good quality; for it gives a pleasant and wholesome juice, and is good for the stomach, and is digestible, and agrees exceedingly well with every one, for it never clogs the bowels, and never relaxes them too much." But Andreas the physician says that there are loaves in Sicily made of the sycamine, and that those who eat them lose their hair and become bald. Mnesitheus says "that wheat-bread is more digestible than barley-bread, and that those which are made with the straw in them are exceedingly nutritious; for they are the most easily digested of all food. But bread which is made of rye, if it be eaten in any quantity, is heavy and difficult of digestion; on which account those who eat it do not keep their health." But you should know that corn which has not been exposed to the fire, and which has not been ground, causes flatulence, and heaviness, and vertigo, and headache.
