acid-ash diet a special diet prescribed to increase the acidity of the urine so that alkaline salts will remain in solution. The diet may be given to aid in the elimination of fluid in certain kinds of edema, in the treatment of some types of urinary tract infection, and to inhibit the formation of alkaline urinary calculi. Meat, fish, eggs, and cereals are emphasized, with little fruit and vegetables and no milk or cheese.
alkali-ash diet a therapeutic diet prescribed to increase the alkalinity of the urine and dissolve uric acid and cystine urinary calculi. This type of diet changes the urinary pH so that certain salts are kept in solution and excreted in the urine. Emphasis is placed on fruits, vegetables, and milk. Meat, eggs, bread, and cereals are restricted.
bland diet one that is free from any irritating or stimulating foods.
pproach to S
ypertension) a diet high in fruits, vegetables, and low-fat dairy products; low in saturated and total fats; low in cholesterol; and high in fiber. Research studies support the hypothesis that this diet reduces blood pressure
and may play a role in prevention of high blood pressure
elemental diet one consisting of a well-balanced, residue-free mixture of all essential and nonessential amino acids combined with simple sugars, electrolytes, trace elements, and vitamins.
elimination diet one for diagnosis of food allergy, based on omission of foods that might cause symptoms in the patient.
a controversial diet for children with attention-deficit/hyperactivity disorder
, which excludes artificial colorings and flavorings, preservatives, and salicylates. The national institutes of health
consensus statement, Diagnosis and Treatment of Attention Deficit Hyperactivity Disorder,
notes that exclusion diets like this are an area warranting additional research.
high calorie diet one that furnishes more calories than needed to maintain weight, often more than 3500–4000 calories per day.
high fat diet
one that furnishes more than 35 per cent of its total calories from fats
; see also ketogenic diet
high fiber diet one high in dietary fiber (typically more than 24 g daily), which decreases bowel transit time and relieves constipation.
high protein diet one containing large amounts of protein, consisting largely of meats, fish, milk, legumes, and nuts.
one that produces ketones or acetones, or mild acidosis, such as one that is low in calories with insufficient carbohydrate and protein; it is occasionally used in the treatment of epilepsy. See also low fat diet
low calorie diet one containing fewer calories than needed to maintain weight, e.g., less than 1200 calories per day for an adult.
low fat diet one containing limited amounts of fat.
low purine diet one for mitigation of gout, omitting meat, fowl, and fish and substituting milk, eggs, cheese, and vegetable protein.
low residue diet
one with a minimum of cellulose and fiber and restriction of connective tissue found in certain cuts of meat. It is prescribed for irritations of the intestinal tract, after surgery of the large intestine, in partial intestinal obstruction, or when limited bowel movements are desirable, as in colostomy patients. Called also low fiber diet
and minimal residue diet
low tyramine diet a special diet required by patients receiving MAO inhibitors. Foods containing tyramine include aged cheeses, red wine, beer, cream, chocolate, and yeast.
protein-sparing diet one consisting only of liquid protein or liquid mixtures of proteins, vitamins, and minerals, containing no more than 600 calories; it is designed to maintain a favorable nitrogen balance. Such diets have been used in weight loss programs, but are used only rarely now, usually only in inpatient settings.
1. a substance that flows readily in its natural state.
2. flowing readily; neither solid nor gaseous.
a diet limited to the intake of liquids or foods that can be changed to a liquid state; it may be restricted to clear liquids or it may be a full liquid diet.
Clear Liquid Diet. This is a temporary diet of clear liquids without residue. It is not nutritionally adequate, and is used in some acute illnesses and infections, postoperatively (especially after gastrointestinal surgery), and to reduce fecal matter in the colon. Foods allowed include water, tea, coffee, fat-free broth, carbonated beverages, synthetic fruit juices, plain gelatin, and sugar.
Full Liquid Diet
. This diet can be nutritionally adequate with careful planning. It is used for acute gastritis
, as a transition between clear liquid and soft diet, and in conditions in which there is intolerance to solid food. Milk, strained soups, and fruit juices are allowed. Foods that liquefy at body temperature, such as ice cream, flavored gelatin, and soft custards, can be included. Cereal gruels and eggnogs are allowed. When a full liquid diet is used as a tube feeding
it must be of a consistency that will allow easy passage through the tube. Most full liquid diets are given in feedings every 2 to 4 hours.
