As would be expected, the diet of the pastoral Arabs consists in great measure of milk, supplemented with moderate amounts of meat, cereals and dates. In settled agricultural districts pomegranates, melons and a few other things enter regularly into the food supply. A great proportion of the wealth of Arabs consists of flocks of sheep and herds of goats and of camels. Cattle and horses are of secondary importance, because they are poor travellers. The milk used is derived from goats and camels and is mostly soured promptly and eaten as curds, because of the impossibility of preserving in a warm climate so perishable a food by other means. Cheese and dried curds are also staple articles of diet among them. This regimen represents a diet largely of a carnivorous nature, but supplemented with more or less of vegetable foods. It is of the greatest importance to these peoples that their diet does contain much milk for they have little opportunity to eat of the articles which are suited for the preparation of salads and greens. They could not subsist upon a meat, cereal and fruit diet without becoming inferior physically.
