What Is a Low Residue Diet and Is It a Good Fit for You?

A low residue diet is a diet that is sometimes prescribed when you have diverticulosis, in some instances of Crohn's disease, ulcerative colitis, or inflammatory bowel disease. But precisely what is a low residue diet, and is it a good fit for you?

If you're experiencing digestive issues, a low residue diet could be part of an excellent treatment plan for you. Let's dive into answering the question: What is a low residue diet?

What Is a Low Residue Diet?

The "residues" in a low residue diet are what we call the components of food that pass through the intestine without being digested. These are things like fiber, which is then meant to be expelled from our bodies. Foods low in residues are easy to digest and absorb. Low residue foods leave less waste in your body and thus decrease bowel movements, allowing the intestines to rest. So, what is a low residue diet? To put it simply, it's a specialized, low fiber diet.

Now that we've answered the question, what is a low residue diet, let's see if it's a good fit you and your dietary needs.

Do You Need a Low Residue Diet?

What is a low residue diet good for? The consumption of foods low in fiber helps to slow down your bowel movements. This helps decrease diarrhea, gas, and inflammation. Your doctor may recommend that you follow a low residue diet if you have:

  • Irritable bowel syndrome
  • Diverticulitis
  • Crohn's disease
  • Ulcerative colitis

A doctor or nutritionist may put you on a low residue diet temporarily after certain types of intestinal surgery, such as an ileostomy or colostomy. You may have to follow this diet only for a short time to give your bowel a break. Or, you may have to stay on the low residue diet longer.

To give your bowel time to heal, you'll need to cut back on fiber.

Types of Fiber

There are two types of fiber:

  • Soluble fiber
  • Insoluble fiber

We can hardly find foods that contain only one type of fiber. Among the foods rich in insoluble fiber, we have whole grains, nuts, little ripe fruits with skin and dried, and certain vegetables (spinach, beans, peas, etc.).

Among the foods rich in soluble fiber, we find skinless and well-ripened fruits such as apples, bananas, pears, quince, legumes without skin, potatoes, carrots, sweet potatoes, flour of corn, and refined white rice.

The type and quantity of fiber available can be modified based on the maturity of the fruit and how it is prepared.

Is a Low Residue Diet Safe?

The low residue diet is recommended in acute phases of ulcerative colitis and enteritis. It is also used as a pre or post-surgical diet. For this reason, a low residue diet should not be considered a long-term lifestyle change.

Restricting fiber consumption for extended periods can lead to vitamin deficiencies. If your doctor has recommended a long term plan for a low residue diet, make sure to follow their instructions. When considering what is a low residue diet and whether it's right for you, remember that bland foods can get boring quickly, leading to binge eating. This could also cause intestinal upset.

Side Effects of Low Residue Diets

By eating foods low in fiber that the body can easily digest, you will effectively decrease bowel movements. Generally, the goal is to eat less than 10 to 15 grams of fiber each day. This must be carefully balanced with vitamins, minerals, proteins, carbohydrates, and fats that are needed. A low residue diet can be a healthy one.

Although it is true that if this diet is maintained for a long time, you may find it necessary to take some supplements (such as folic acid and vitamin C). Besides getting bored with bland food, a low residue diet can lead to anemia or vitamin C deficiency, which can lead to scurvy. Another common side effect of this diet is constipation. Make sure to stay hydrated to avoid this.

Is a Low Residue Diet Right for Me?

Now that we've answered "What is a low residue diet," and "Is it right for me?" you may have additional questions. You will probably continue this diet for a short period only since low-residue foods generally do not provide all the nutrients needed to maintain good health.

General Advice for a Low Residue Diet

When choosing foods for a low residue diet, select foods with low sugar content and added fat. When developing a strict diet plan like a low residue diet, your body may not be receiving all the vitamins and minerals it needs to stay healthy. Therefore, you may have to take supplements, such as a multi-vitamin.

Your doctor will tell you how long you should follow this diet, and you may also recommend specific vitamins to ensure you get enough nutrients. Always check with your doctor or dietitian before beginning any supplement treatments.
