Jaw Surgery — Post-Surgical Diet Instructions

To determine required caloric intake:

Body wt (kg) x 30 = Daily kcal necessary for weight maintenance

(e.g., presurgical weight (70kg) x 30 = 2100 kcal/day)

To determine protein/healing needs (healthy individual):

Body wt (kg) x 1.0 g = grams protein/day

(e.g., presurgical weight (70kg) x 1 = 70 g protein/day)

* To determine wt in kg divide wt (lbs.) by 2.2

> 3000 ml fluid requirement daily

The Blenderized Diet


These guidelines are for persons who require a blenderized diet after oral or facial surgery. This diet is well balanced with enough calories, protein and fluids to meet your body’s needs. It will help keep you from losing weight and will help heal your wounds.

General Instructions:

All foods must be in a liquid form, thin enough to go through a syringe or drink from a spoon, child’s feeding cup or glass. Straws may be used one week after surgery. You should not need to chew. Food must be strained to remove chunks of seed or fibers that can get caught in the wires.


  • Clean your mouth after each meal to prevent infections.
  • Take frequent small feedings (6-8/day)
  • Please brush the teeth at minimum four times per day for 5-10 minutes each time and use mouth rinse as directed.

This is not the time to lose extra weight. Surgery is a stress that causes extra work for your body. To fight infection and heal wounds, your body needs more calories and protein than it normally would.

This includes 8-10 glasses of fluid a day and all essential vitamins and minerals.

Eat various foods from all the food groups in order to get a balanced diet adequate in vitamins, minerals, and protein.

If you are unable to eat an adequate variety of foods daily, you should consider taking a liquid multivitamin/mineral supplement that provides 100% of the RDA. Tablets may be crushed & combined with blenderized food.

For additional calories, eat extra servings from the four food groups and include fats, sweets, desserts and supplements.

Basic Food Groups:


(4 or more servings each day. 1 serving = 8oz.)

Drink whole or skim, or low-fat buttermilk, or smooth yogurt. Milk is used as a beverage or to thin cream soups or ice cream for milkshakes. Make pudding and custard with double the usual amount of milk so it is thin.

Meats or Meat Substitutes:

(4 or more servings. 1 serving = 1 ounce meat or cheese; ¼ cup pasteurized egg)

Meat, poultry, fish and eggs are part of the meat group. Cook meats until they are soft. Liquefy in a blender until the desired consistency.

Avoid using raw eggs to prevent the chance of food poisoning; use a pasteurized egg product instead of fresh eggs.

Cottage cheese must be blenderized. Melt pasteurized processed cheese, cream, Parmesan or cheddar cheeses before serving. Some cheeses may be too stringy when melted to pass through the jaw wires.

Avoid fried meats or eggs, meats or cheeses with casings or whole spices or seeds, and tough meats with a lot of cartilage.

Fruits & Vegetables:

(3 or more servings fruit and 3 or more servings vegetables each day. 1 serving = ½ cup)

Fruit juices provide the easiest way to include fruit in the diet. Include a serving (1/2 cup) of orange, grapefruit, or tomato juice each day for Vitamin C.

Liquefy soft fruits or canned fruits in a blender. Strain and thin these fruits with compatible fruit juice. Cook vegetables until tender and liquefy in a blender.

Strain and thin them to the desired consistency. Avoid fruits and vegetables with seeds, such as berries or tomatoes.

Tough skins or hulls on vegetables should be avoided. This includes corn, lima beans, and dried or raw fruits and vegetables.

Starches – Breads & Cereals:

(4 or more servings a day. 1 serving = ½ cup)
Thin refined, enriched cooked cereals such as Farina, Grits, Malt-O-Meal, Cream of Wheat, or Cream of Rice with milk should be used. Mash cooked white or sweet potatoes and thin with milk.

Soups with noodles, rice, or vegetables may be liquefied in a blender. Use gravy, strained sauces or soup to thin enriched white rice and pasta made from refined, enriched flour.

Avoid whole grain or bran cereals and starches with nuts or seeds. Do not eat cooked dried beans unless they are split and the hulls removed (split peas, split lentils).

Soups, fats, desserts, sweets can be consumed in any amount desired.

Preparing Blenderized Food:


  • Blender, or food processor or food mill
  • Fine wire strainer
  • Wire whip or fork
  • Plastic container with labels for freezing

Use cooked foods. Avoid fresh fruits and vegetables, and tough or gristly meats, as they are difficult to puree. No raw eggs.

Avoid nuts, seeds, whole grain or bran cereals, starches, and foods with tough skins or hulls. These foods do not blenderize well and leave particles that can get trapped in wires.

To liquefy in a blender:

  1. Put small pieces of solid food in blender (one serving = 1/2 – 3/4 cup)
  2. Add a small amount (1/4 cup) fluid
  3. Blend until pureed
  4. Strain through jelly strainer to remove particles

Liquids to Use:

  • Cream soups, strained
  • Fruit juice
  • Tomato or vegetable juice
  • Ice cream without nuts
  • Smooth yogurt without fruit or nuts
  • Clear soups
  • Broth
  • Half & half
  • Sour cream
  • Cream
  • Milk


Use one of the following supplements available in most grocery or drug stores if you need higher calories:

  • Instant Breakfast drinks
  • Resource and Resource Plus (Novartis)
  • Ensure and Ensure Plus (Ross Laboratories)
  • Sustacal (Mead Johnson)
  • NuBasics Drink (Nestle)

Add 2 tablespoons powdered milk to each cup:

  • Mashed potatoes
  • Cooked cereals
  • Soup
  • Puddings
  • Milk drinks

Drink skim milk powder used in:

  • High protein milk
  • High protein eggnog
  • High protein milkshake

You can also increase calories by adding any of the following to blenderized foods:

  • Melted butter, margarine, cream cheese or shortening
  • Vegetable oil, mayonnaise and smooth salad dressing
  • Strained gravy and cream sauces
  • Sugar, honey, plain syrups
  • Melted smooth peanut butter

Consuming high-calorie drinks such as peach, pear or papaya nectars, cranberry juice, grape, orange juice or lemonade can help and taste good too. Eggnog, available around the holidays, is a great source of calories!

High Protein Milkshake Recipe


  • ½ cup ice cream without nuts
  • ½ cup milk
  • 2 Tbsp. skim milk powder


  1. Make a paste of the milk and powder.
  2. Mix until smooth.
  3. Add ice cream and beat with mixer or blender.
  4. Flavor as desired.

Foods should be refrigerated or frozen within an hour after preparation. Blenderized foods can be refrigerated up to 48 hours, as they are an excellent medium for the growth of bacteria.

Extra portions can be frozen in meal-size amounts in covered ice cube trays and should be frozen immediately after blenderizing if kept in this manner.

Additional Information:

  • Strained baby food and baby cereal may be used from the jar without further blending or straining. Junior foods should be blenderized
  • Solid fats and cheese blend more easily if they are first melted. Oil, salad dressing and cream can be added directly to the puree.
  • Frozen desserts and gelatin must be melted to a liquid before they can be eaten.
  • Eat balanced meals that are adequate in calories, protein, vitamins, minerals and fluid.

Weigh yourself weekly. It is common for weight to vary 2-3 pounds a week.

If you lose 5 pounds or more in one week, call your doctor. You may not be eating or drinking enough.

Season blenderized foods with salt, ground pepper, any ground spice, and seasoned salts. Use condiments that don’t have whole spices in them such as prepared mustard, catsup, steak sauce or Tabasco sauce. Avoid anything that has bacon bits, whole spices, seeds, nuts or coconut in it.
