_Variety_ in the selection of foods for the table is an essential feature,
but this should not increase either the work or the expense of supplying
the meals. Each single meal can, and should, be simple in itself and, at
the same time, differ sufficiently from the meal preceding and the one
following to give the necessary variety in the course of the day. The bill
of fare should, of course, include fruits (for their tonic effects) and
very small amounts perhaps of substances which stimulate the appetite,
such as pepper, mustard, etc., known as condiments.
*Purity of Food.*—The fact that many of the food substances are perishable
makes it possible for them to be eaten in a slightly decayed condition.
Such substances are decidedly unwholesome (some containing poisons) and
should be promptly rejected. Not only do fresh meats, fruits, and
vegetables need careful inspection, but canned and preserved goods as
well. If canned foods are imperfectly sealed or if not thoroughly cooked
in the canning process, they decay and the acids which they generate act
on the metals lining the cans, forming poisonous compounds. The contents
of "tin" cans should for this reason be transferred to other vessels as
soon as opened.
