Types of Therapeutic Diets A therapeutic diet is a meal plan that controls the intake of certain foods or nutrients. It is part of the treatment of a medical condition and are normally prescribed by a physician and planned by a dietician. A therapeutic diet is usually a modification of a regular diet. It is modified or tailored to fit the nutrition needs of a particular person. Therapeutic diets are modified for (1) nutrients, (2) texture, and/or (3) food allergies or food intolerances. Common reasons therapeutic diets may be ordered: • To maintain nutritional status • To restore nutritional status • To correct nutritional status • To decrease calories for weight control • To provide extra calories for weight gain • To balance amounts of carbohydrates, fat and protein for control of

diabetes • To provide a greater amount of a nutrient such as protein • To decrease the amount of a nutrient such as sodium • To exclude foods due to allergies or food intolerance • To provide texture modifications due to problems with chewing and/or

swallowing Common therapeutic diets include: 1. Nutrient modifications

• No concentrated sweets diet • Diabetic diets • No added salt diet • Low sodium diet • Low fat diet and/or low cholesterol diet • High fiber diet • Renal diet

2. Texture modification

• Mechanical soft diet • Puree diet

3. Food allergy or food intolerance modification • Food allergy • Food intolerance

4. Tube feedings

• Liquid tube feedings in place of meals • Liquid tube feedings in addition to meals

5. Additional feedings – In addition to meal, extra nutrition may be

ordered as: • Supplements – usually ordered as liquid nutritional shakes once,

twice or three times per day; given either with meals or between meals

• Nourishments – ordered as a snack food or beverage items to be given between meals mid-morning and/or mid-afternoon

• HS snack – ordered as a snack food or beverage items to be given at the hour of sleep

The following list includes brief descriptions of common therapeutic diets: Clear liquid diet – • Includes minimum residue fluids that can be seen through. • Examples are juices without pulp, broth, and Jell-O. • Is often used as the first step to restarting oral feeding after surgery or

an abdominal procedure. • Can also be used for fluid and electrolyte replacement in people with

severe diarrhea. • Should not be used for an extended period as it does not provide

enough calories and nutrients. Full liquid diet – • Includes fluids that are creamy. • Some examples of food allowed are ice cream, pudding, thinned hot

cereal, custard, strained cream soups, and juices with pulp. • Used as the second step to restarting oral feeding once clear liquids are

tolerated. • Used for people who cannot tolerate a mechanical soft diet. • Should not be used for extended periods.

No Concentrated Sweets (NCS) diet – • Is considered a liberalized diet for diabetics when their weight and blood

sugar levels are under control. • It includes regular foods without the addition of sugar. • Calories are not counted as in ADA calorie controlled diets. Diabetic or calorie controlled diet (ADA) – • These diets control calories, carbohydrates, protein, and fat intake in

balanced amounts to meet nutritional needs, control blood sugar levels, and control weight.

• Portion control is used at mealtimes as outlined in the ADA “Exchange List for Meal Planning.”

• Most commonly used calorie levels are: 1,200, 1,500, 1,800 and 2,000. No Added Salt (NAS) diet – • Is a regular diet with no salt packet on the tray. • Food is seasoned as regular food. Low Sodium (LS) diet – • May also be called a 2 gram Sodium Diet. • Limits salt and salty foods such as bacon, sausage, cured meats,

canned soups, salty seasonings, pickled foods, salted crackers, etc. • Is used for people who may be “holding water” (edema) or who have

high blood pressure, heart disease, liver disease, or first stages of kidney disease.

Low fat/low cholesterol diet – • Is used to reduce fat levels and/or treat medical conditions that interfere

with how the body uses fat such as diseases of the liver, gallbladder, or pancreas.

• Limits fat to 50 grams or no more than 30% calories derived from fat. • Is low in total fat and saturated fats and contains approximately 250-300

mg cholesterol. High fiber diet – • Is prescribed in the prevention or treatment of a number of

gastrointestinal, cardiovascular, and metabolic diseases. • Increased fiber should come from a variety of sources including fruits,

legumes, vegetables, whole breads, and cereals.

Renal diet – • Is for renal/kidney people. • The diet plan is individualized depending on if the person is on dialysis. • The diet restricts sodium, potassium, fluid, and protein specified levels. • Lab work is followed closely. Mechanically altered or soft diet – • Is used when there are problems with chewing and swallowing. • Changes the consistency of the regular diet to a softer texture. • Includes chopped or ground meats as well as chopped or ground raw

fruits and vegetables. • Is for people with poor dental conditions, missing teeth, no teeth, or a

condition known as dysphasia. Pureed diet – • Changes the regular diet by pureeing it to a smooth liquid consistency. • Indicated for those with wired jaws extremely poor dentition in which

chewing is inadequate. • Often thinned down so it can pass through a straw. • Is for people with chewing or swallowing difficulties or with the condition

of dysphasia. • Foods should be pureed separately. • Avoid nuts, seeds, raw vegetables, and raw fruits. • Is nutritionally adequate when offering all food groups. Food allergy modification – • Food allergies are due to an abnormal immune response to an

otherwise harmless food. • Foods implicated with allergies are strictly eliminated from the diet. • Appropriate substitutions are made to ensure the meal is adequate. • The most common food allergens are milk, egg, soy, wheat, peanuts,

tree nuts, fish, and shellfish. • A gluten free diet would include the elimination of wheat, rye, and barley.

Replaced with potato, corn, and rice products. Food intolerance modification – • The most common food intolerance is intolerance to lactose (milk sugar)

because of a decreased amount of an enzyme in the body. • Other common types of food intolerance include adverse reactions to

certain products added to food to enhance taste, color, or protect against bacterial growth.

• Common symptoms involving food intolerances are vomiting, diarrhea, abdominal pain, and headaches.

Tube feedings – • Tube feedings are used for people who cannot take adequate food or

fluids by mouth. • All or parts of nutritional needs are met through tube feedings. • Some people may receive food by mouth if they can swallow safely and

are working to be weaned off the tube feeding.
