Fats may be supplied in the yolks of eggs, cream, butter, cheese, bacon, and oily nuts, as butternuts, Brazil nuts, almonds, hazel nuts, walnuts, pecans; all should be well chewed. In beginning a diet, the change must not be too sudden. Potatoes, when they agree, may be used in small quantities as a substitute for bread. At least a week’s time should be allowed for the elimination of all sugar and starch. Begin by eliminating sugars and next bread, cereals, anything made with flour, and potatoes. Sometimes it is necessary to begin with an all milk diet for a day or two. Van Noorden gives the following diet, free from carbohydrates, which has been in general use in Europe and America. _Breakfast_ Tea or coffee, 6 ounces. Lean meat (beefsteak, mutton chop, or ham), 4 ounces. Eggs, one or two. _Lunch_ Cold roast beef, 6 ounces. Celery, or cucumbers, or tomatoes with salad dressing. Coffee, without milk or sugar, 2 ounces. _Dinner_ Bouillon, 6 ounces. Roast beef, 7-1/2 ounces. Green salad, 2 ounces. Vinegar, 2-1/2 drams. Butter, 2-1/2 drams. Olive oil, 5 drams, or spinach with mayonnaise, large portion. _Supper, 9 P. M._ Two eggs, raw or cooked. Van Noorden includes alcohol, in whisky, in his diet and most physicians follow the theory that alcohol aids in the digestion and absorption of fats; the need is recognized since fats must be supplied, yet the sweet wines and beers contain sugar while the sour wines contains acids, which may disturb digestion. _DERANGEMENTS OF LUNGS AND BRONCHI_ [Sidenote: Asthma] In this affection the free entrance of air into the lungs as well as its free exit is hampered by a condition of the bronchial muscles, the mucous membrane of the bronchi, and the muscles of the diaphragm. The muscles contract spasmodically without due or proper relaxation. This causes a congestion and swelling of the mucous membrane of the bronchi which still further hamper the ingress and egress of air. Any digestive derangement which causes the formation of gas distends the stomach and intestines, interferes with the free action of the diaphragm, and prevents the free movement of the abdominal muscles. The chemical action of the undigested and fermenting substances in the digestive tract irritates the nerves and may cause the spasm of the muscles. Digestive derangements will often cause the onset of an attack of asthma in those afflicted with this disorder. The correction of the conditions in the stomach and intestinal tract will often ameliorate the attacks. Care must be taken not to overload the stomach and intestines, to eat easily digested foods which agree in the particular case. All food found to cause any digestive disturbance should be avoided. Constipation must be remedied by gentle exercises and massage of the abdomen as free elimination removes material which might aid in inciting an attack.
