FISH IN THE DIET

Instructions:
Fish can usually be purchased at a lower price than meat, and for this reason possesses an economic advantage over it. Besides the price, the substitution of fish for meat makes for economy in a number of ways to which consideration is not usually given.
- These will become clearly evident when it is remembered that nearly all land animals that furnish meat live on many agricultural products that might be used for human food. Then, too, other foods fed to animals, although not actually human foods, require in their raising the use of soil that might otherwise be utilized for the raising of food for human beings. This is not true in the case of fish.
- They consume the vegetation that grows in lakes, streams, and the ocean, as well as various kinds of insects, small fish, etc., which cannot be used as human food and which do not require the use of the soil.
- In addition, much of the food that animals, which are warm-blooded, take into their bodies is required to maintain a constant temperature above that of their surroundings, so that not all of what they eat is used in building up the tissues of their bodies.
- With fish, however, it is different. As they are cold-blooded and actually receive heat from their surroundings, they do not require food for bodily warmth. Practically all that they take into the body is built up into a supply of flesh that may be used as food for human beings.
- With fish, as with other foods, some varieties are sought more than others, the popularity of certain kinds depending on the individual taste or the preference of the people in a particular locality.
- Such popularity, however, is often a disadvantage to the purchaser, because a large demand for certain varieties has a tendency to cause a rise in price. The increased price does not indicate that the fish is of more value to the consumer than some other fish that may be cheaper because it is less popular, although quite as valuable from a food standpoint.
- The preference for particular kinds of fish and the persistent disregard of others that are edible is for the most part due to prejudice. In certain localities, one kind of fish may be extremely popular while in others the same fish may not be used for food at all.
- Such prejudice should be overcome, for, as a matter of fact, practically every fish taken from pure water is fit to eat, in the sense that it furnishes food and is not injurious to health. In addition, any edible fish should be eaten in the locality where it is caught.
- The transportation of this food is a rather difficult matter, and, besides, it adds to the cost. It is therefore an excellent plan to make use of the kind of fish that is most plentiful, as such practice will insure both better quality and a lower market price.
- As is well known, fish is an extremely perishable food. Therefore, when it is caught in quantities too great to be used at one time, it is preserved in various ways. The preservation methods that have proved to be the most satisfactory are canning, salting and drying, smoking, and preserving in various kinds of brine and pickle.
- As such methods are usually carried out in the locality where the fish is caught, many varieties of fish can be conveniently stored for long periods of time and so distributed as to meet the requirements of the consumer. This plan enables persons far removed from the Source of supply to procure fish frequently.
- In general, the composition of fish is similar to that of meat, for both of them are high-protein foods. However, some varieties of fish contain large quantities of fat and others contain very little of this substance, so the food value of the different kinds varies greatly. As in the case of meat, fish is lacking in carbohydrate.
- Because of the close similarity between these two foods, fish is a very desirable substitute for meat. In fact, fish is in some respects a better food than meat, but it cannot be used so continuously as meat without becoming monotonous; that is to say, a person will grow tired of fish much more quickly than of most meats.
- The similarity between the composition of fish and that of meat has much to do with regulating the price of these protein foods, which, are the highest priced foods on the market.
