Elemental Diet - An Overview

Introduction

An elemental diet is a powdered or liquid replacement for a complete meal broken down into its most elemental or easily absorbable form. This meal is easily absorbed by the upper gastrointestinal tract, allowing it to rest or recover from injury.

What Is an Elemental Diet?

An elemental diet is a powdered or liquid replacement for a complete meal that has been broken down into its most elemental or easily absorbable form. For example, proteins, fats, and carbohydrates are split down into simpler components, such as amino acids, short-chain triglycerides (or fatty acids), and sugars, combined with other vitamins, minerals, and electrolytes. The upper gastrointestinal tract absorbs it easily, allowing it to rest or recover from injury.

Who Should Adhere to an Elemental Diet?

An elemental diet is usually suggested for those with severe digestive issues or who are recovering from gastrointestinal surgery and requiring rest. It has been helpful in the following conditions:

1. Inflammatory or autoimmune conditions

• Crohn’s disease (an inflammatory bowel disease where the digestive system becomes swollen).

• Colitis (irritation of the large intestine usually caused by taking some antibiotics).

• Chronic pancreatitis (inflammation of the pancreas).

• Eosinophilic esophagitis (inflammation of the esophagus with an increase in white blood cells).

• Celiac disease (problems in the digestive system caused by having gluten).

• Arthritis (a common disorder that causes pain in the joints).

• Irritable Bowel Syndrome.

• Radiation enteritis (inflammation of the intestine caused by radiation).

• Food allergies or intolerance to certain food.

• Small intestinal bacterial overgrowth.

2. Conditions requiring supplemental nutrition

• Anorexia (an eating disorder).

• HIV/AIDS.

• Cancer.

3. Conditions where the digestive system is fully functional

• Short bowel syndrome (the bowel does not absorb sufficient nutrients and fluids).

• Pancreatic insufficiency (a condition where the body lacks enzymes to digest food).

In these conditions, people have issues with their digestive tract and can have trouble digesting normal food, resulting in malabsorption, dehydration, and other issues. An elemental diet can also ease digestive disorders like constipation, diarrhea, stomach pain, vomiting, etc.

Who Shouldn't Follow an Elemental Diet?

• Diabetes patients: An elemental diet is already rich in sugars and carbohydrates and can cause sugar hikes in diabetes patients.

• People trying to lose weight.

How Does an Elemental Diet Work?

Those advised on an elemental diet are only allowed to take this as a source of nutrition. Water and plain tea can also be taken. However, they are not allowed to have any solid food. An elemental diet is available in liquid or powder form that can be mixed with water and taken as a drink. It is always advisable to consume the drink at a slow pace to prevent any stomach discomfort or cramps. Many commercially available elementary diets are designed to provide sufficient nutrients and calories. A dietitian or a medical officer should always prescribe an elemental diet after calculating the calories and nutrition required. In most cases where the patient is severely ill, an elemental diet is the only source of nourishment. Sometimes, the patient is allowed to consume half of the calories and nutrition as solid food, while an elemental diet provides the other half.

What Are the Possible Side effects of an Elemental Diet?

During an elemental diet, the side effects you experience might make you doubt if the condition worsens. Medical guidance can help us solve this problem. The side effects encountered can include;

• Abdominal cramping: During the initial days of the liquid diet, the feces stuck to the colon will be cleared, which can cause gas and abdominal pain as the residual feces is pushed out. This condition will get better gradually as the colon gets clean.

• Detox symptoms: As the liver has a lesser duty to do, it will flush off its extra toxins, which can cause some symptoms like headache, lightheadedness, nausea, vomiting, and fatigue. These symptoms make us feel tired initially but will get better as the toxins are flushed out.

• Bacteria die-out symptoms: If there is an issue of bacterial overgrowth or fungal overgrowth in the small intestine, being on an elementary diet will starve the flora, leading to its destruction. This can also present as detox symptoms, which will gradually pass off as the body gets cleaner.

• Reduced motility: Sometimes, bowel movements can be less while on an elementary diet. This may create the idea that the patient has constipation. This diet does not cause constipation, though it slows down bowel movements.

How Can an Elemental Diet Be Stopped?

It is always advisable to introduce solid foods gradually, as the body requires time to adapt. Doctors usually recommend a "half-element" diet (introducing solid food for half the calorie count and relying on the elemental diet for the rest). Probiotics are also advised to fill the gut with gut-friendly bacteria. Prokinetic agents may also be included to increase bowel movements.

What Are the Advantages of an Elemental Diet?

The main benefits of the diet are:

• Bowel rest: This enables the bowel to heal without compromising nutrition.

• Reduce inflammation: Many digestive disorders are due to inflammatory flare, affecting the digestive system and the quality of life.

• Reduction in bacterial overgrowth: The type of bacteria that causes difficulties depends upon the undigested food in the small intestine. Being on an elemental diet will starve these bacteria, causing their destruction.

What Are the Disadvantages of an Elemental Diet?

The following are some disadvantages of an elemental diet:

• Taste: Elemental diets can be flavored, but they might not appeal to the mouth. Moreover, having the same flavor long can make us bored.

• Can be depressing: It can be boring to have the same taste and consistency for a long time. It can be depressing, especially for those who have an emotional attachment to food.

• High carbohydrate: It might not be suitable for people who suffer from intolerance and diabetes.

• Expensive: This is more expensive than a normal meal since it is synthetic and easily digestible.

Conclusion

An elemental diet is one of the most useful therapies for gut healing. Since it is already in its simplest form, the digestive system gets time to rest and regenerate itself, promoting healing.
