In fevers due to poisons circulating in the blood, there is an interference with heat regulation, so that the heat generated in the body cannot be gotten rid of in the normal way; an increased metabolism; and a disturbance of the digestive and absorptive functions. It is, therefore, desirable to give easily digested food, in small quantities at frequent intervals, preferably in liquid form, as substances dissolved in water are more readily absorbed, and water tends to aid in cooling the body to normal temperature.

For the first three or four days, patients previously strong, should be given only fluid foods. But since a normal man, lying quietly in bed, requires about 2000 calories to compensate for daily loss of energy, and in the increased metabolism of fever, this requirement is increased, it is necessary that more substantial food be incorporated into the diet as far as is possible without disturbing digestion.

Diet

Milk is the staple food, but must be given with care, swallowed very slowly and diluted with limewater, soda, seltzer or other effervescent water - one part to two parts milk.

If milk can be taken, two or three pints should be given - four ounces every two hours, or six ounces every three hours. In case milk does not agree, whey may be given as a substitute for milk in part or in whole. Modified milk or peptonized milk may be given. Sometimes the milk may be flavored with tea, coffee, cocoa or malted milk and junket used.

Next to milk the most important article of diet is beef juice and broths. Next come well cooked gruels. Later well prepared cereals and malt extract are valuable, and plain or cocoa junkets. Usually there is thirst, and all acid drinks, such as grape juice, may be taken.

Panopepton with crushed ice, peptonised milk, clam, mutton and chicken broth, beef tea, clear soups, thickened with some farinaceous substance, gelatin jellies, are all of value.

Liquids

• Pure cold water, toast water, any of the acid drinks, all sipped slowly, are recommended both to relieve thirst and on account of facilitating the speed with which the waste matter resulting from increased metabolism of the fever is eliminated through the kidneys.

Avoid

Any solid or vegetable food or fruits, until permitted by the physician in charge.
