diet
[di´et] 1. the customary amount and kind of food and drink taken by a person from day to day.
2. more narrowly, a regimen of food intake planned to meet specific requirements of the individual, including or excluding certain foods. See also nutrition.
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.
DASH diet (
Dietary
Approach to
Stop
Hypertension) 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.
Feingold diet 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.
ketogenic diet 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.
gluten
[gloo´ten] the protein derivative of wheat and other grains that gives dough its tough elastic character; avoidance of this substance will alleviate
celiac disease (nontropical sprue) in certain persons, as well as immunologic disturbances in which there is an allergy to gliadin, a component of gluten.
gluten-free diet a diet in which wheat must be avoided, as well as other grains such as barley, oats, and rye that contain analogues to wheat gluten. Exceptions to this essentially grain-free diet are corn, rice, and millet. Wheat starch, which has been washed free of
gliadin, is not restricted nor are there restrictions on carbohydrates or fats.
Patient Care. Following a gluten-free diet can relieve the problems associated with gluten allergy but preparing and enjoying gluten-free meals demands constant vigilance and motivation. Patients and family members who purchase and prepare patients' foods should read the labels on processed foods very carefully. Many contain hidden and unexpected wheat flour, for example, tomato catsup and ice cream. Processors also mix unacceptable and acceptable gluten-free soybeans and grains together in the same product. If there are any questions about the contents of a product, manufacturers will provide lists of their foods that are permissible on a gluten-free diet.
Foods to be avoided are listed in the accompanying table, as well as possible sources of hidden gluten. Additional information and recipes for baking with nongluten flours can be obtained from a dietitian or from publications found in most large bookstores.
