Dietary Approaches to Stop Hypertension diet

Abbreviation: DASH diet
A diet proven to treat stage I hypertension, consisting of generous amounts of cereals, fruits, and vegetables (for fiber, vitamins, and minerals), low-fat dairy products, nuts, and lean meats (to maximize protein intake without too much saturated fat and cholesterol). Guidelines for a diet of 2000 calories daily include seven to eight servings of grains and grain products; four to five servings of vegetables; four to five servings of fruits; two to three servings of low-fat or nonfat dairy products; two or fewer servings of lean meats, proteins, and fish. The plan also permits four to five servings of nuts, seeds, and legumes per week. It is recommended that sodium intake be less than 3000 g/day. The complete diet provides more specific recommendations for sodium. Compared with the diet recommended in the Food Guide Pyramid, this diet contains more fruits and vegetables but less fat.

Liquid diet.

gluten-free diet

A diet that excludes gluten by eliminating all products containing wheat, rye, or barley. Foods containing buckwheat, corn, oats, quinoa, and rice are generally thought to be well tolerated. Because gluten is present in many foods containing thickened sauces, the diet must be discussed with a dietitian. It is the basis of management for celiac disease. See: celiac sprue; sprue

high-calorie diet

A diet that contains more calories than normally required for a person's metabolic and energy needs and therefore places that person in positive energy balance. The diet should include three meals and between-meal snacks and exclude fermentable and bulky foods. A high-calorie diet may be used to prevent weight loss in wasting diseases, in high basal metabolism, and after a long illness; in deficiency caused by anorexia, poverty, and poor dietary habits; and during lactation (when an extra 1000 and 1200 kcal each day are indicated).

See: carbohydrate loading

Lay people may refer to a high-residue diet as one containing a lot of roughage. See: fiber

Inuit diet

Eskimo diet.

Kempner rice-fruit diet

See: Kempner rice-fruit diet

light diet

A diet consisting of all foods allowed in a soft diet, plus whole-grain cereals, easily digested raw fruits, and vegetables. Foods are not pureed or ground. This diet is used as an intermediate regimen for patients who do not require a soft diet but are not yet able to resume a full diet.

liquid diet

A diet for those unable to tolerate solid food or for patients whose gastrointestinal tract must be free of solid matter. This type of diet may contain coffee with hot milk, tea, water, milk in all forms, milk and cream mixtures, cocoa, strained cream soups, fruit juices, meat juices, beef bouillon, tea, clear broths, gruels, strained meat soups, and eggnog. Synonym: fluid diet

Its use has been associated on occasion with cardiac rhythm disturbances and sudden cardiac death.

low carbohydrate, hypocaloric diet

A diet that limits total calories usually to about 1200 calories per day and total carbohydrates to no more than about 25% of total calories. Although this diet does not create more weight loss than calorically restricted high-carbohydrate diets, it does reduce fasting levels of insulin and triglycerides and may be preferable for inactive or obese patients with type 2 diabetes mellitus or impaired glucose tolerance.

low-fat diet

An imprecise term for a diet in which the percentage of calories derived from fatty foods is limited (usually to less than 30% of total calories).

low-protein diet

A diet that contains a limited amount of protein. The principal sources of food energy are fats and carbohydrates. This diet is used to treat end-stage renal and hepatic disease.

low-salt diet

Low-sodium diet.

low-sodium diet

A diet containing about 500 mg (approx. 10 mmol) of sodium daily. It is used occasionally to help manage hypertension, congestive heart failure, or renal failure. On this diet, table salt should not be added to food, and the salt content of commonly used beverages such as beer or soft drinks should be noted. To help regulate sodium consumption, sodium-containing medicines should be avoided.
Synonym: low-salt diet; sodium-free dietsalt-free diet

macrobiotic diet

See: pescovegetarian

Mediterranean diet

A well-tolerated, palatable diet that mimics the traditional cuisine of Italy, Greece, and the islands of the Mediterranean Sea. It includes fish and other seafood, wine, and olive oil, and derives about 25% to 35% of its calories from fat, but the primary fat is olive oil, a monounsaturated fat. Additional healthy fats are supplied by grapeseed oil and fats in whole vegetables, nuts, and seeds.

minimum residue diet

prudent diet

A diet to protect against heart disease, stroke, and other common diseases. It consists of fruits, vegetables, whole grains, legumes, nuts, fish, and low-fat dairy products rather than refined or processed foods, red meats, high concentrated sweets, eggs, and butter. A multistep approach decreases fat, cholesterol, and protein.

purine-restricted diet

A diet that limits purine and fats and encourages fluid intake; used to control the excessive levels of uric acid caused by gout. High purine foods include sweetbreads, anchovies, sardines, liver, beef kidneys, brains, and herring. Historically, gout was thought of as a disease of the wealthy, because only wealthy individuals could afford to eat such foods. It is now much more widespread, and its causes are known to be more diverse.

reducing diet

A diet to help people lose weight by restricting the number of calories and carefully balancing other nutrients.
Synonym: calorie reduction diet

residue-free diet

Abbreviation: TLC diet
A diet in which fat calories make up between 25% and 35% of total caloric intake; less than 7% of each day's total calories come from saturated fat; total cholesterol intake is less than 200 mg; and total calories are adjusted to achieve and sustain a healthy weight and serum cholesterol.

tyramine-free diet

very low calorie diet

A commercially available diet in which caloric intake may be from 400 to 800 kcal/day. This diet is usually in the form of a powdered supplement taken 3 to 5 times a day with large amounts of water. This diet can be effective, but the long-range efficacy in maintaining the weight loss may be discouraging. Vitamins and minerals are typically added to this diet because the small number of macronutrients consumed are inadequate for daily needs.

weight reduction diet

A diet that reduces the caloric content enough to cause weight loss. Normal metabolism must be preserved, and bulk, mineral, protein, vitamin, and water requirements must be met. Weight will be reduced if the caloric dietary intake is less than the calories used in activity. To lose 1 pound of weight, one would need a caloric deficit of 3500 calories (the number of calories in one pound). Therefore, if one were to decrease food intake by 300 calories a day and exercise enough to burn 200 calories more than usual, in 7 days one will lose 1 pound.

wellness diet

Anti-inflammatory diet.

Western diet

A diet with inadequate fruits, vegetables, whole grains, legumes, fish, and low-fat dairy products and excessive amounts of refined and processed foods, alcohol, salt, red meats, sugary beverages, snacks, eggs, and butter. The Western diet, which is low in potassium, high in sodium, fats, and simple carbohydrates, has been implicated in many diseases, including atherosclerosis, type II diabetes, hypertension, and obesity.
