According to the American College of Allergy, Asthma & Immunology, dietary therapy can be a highly effective treatment for Eosinophilic Esophagitis (EoE), successfully inducing remission in many patients. This article explores what is the best diet for people with EoE, detailing the most common elimination and elemental approaches to manage this inflammatory condition.

Quick Summary

This guide provides an overview of dietary strategies for managing Eosinophilic Esophagitis, including different elimination and elemental diet types, their effectiveness, and vital nutritional considerations for long-term health and wellness.

Key Points

Start with Less Restriction: A step-up diet, beginning with eliminating just milk and wheat, is often the most practical and manageable starting point for EoE dietary therapy.
Elemental Diet is a Last Resort: While highly effective, the elemental diet is very restrictive and is typically reserved for severe, refractory EoE or for younger children who have failed other options.
Milk and Wheat are Top Triggers: Research consistently shows that cow's milk and wheat are the most common food triggers for EoE across various populations.
Collaboration is Critical: Successfully managing an EoE diet requires working closely with a gastroenterologist and a registered dietitian to ensure nutritional needs are met and the reintroduction phase is handled properly.
Biopsies are Necessary: Endoscopies with biopsies are the only reliable method for assessing if a diet change has successfully induced histologic remission, as symptoms alone are not a reliable indicator.
Cross-Contamination is a Real Risk: Patients on elimination diets must be vigilant about avoiding cross-contamination in both their own kitchens and when eating out.
Dietary Therapy is Not Forever: The goal of elimination diets is to identify the specific triggers, allowing patients to liberalize their diet over time rather than remaining on a broad elimination diet indefinitely.
Nutritional Adequacy is Key: A registered dietitian can help manage dietary restrictions and prevent nutrient deficiencies, ensuring a healthy and balanced diet despite food eliminations.

Understanding the Dietary Connection to EoE

Eosinophilic Esophagitis (EoE) is a chronic, immune-mediated disease where food antigens are the primary triggers of inflammation in the esophagus. Unlike typical food allergies, EoE is a non-IgE mediated response, meaning common skin-prick or blood tests are not reliable for identifying trigger foods. The most common food triggers consistently identified in research are milk, wheat, soy, and egg, with nuts, fish, and shellfish being less frequent triggers.

Because EoE is triggered by food, dietary elimination is one of the most effective treatments, rivaling medication in its ability to resolve symptoms and inflammation. The goal of any EoE diet is to identify and remove the specific food triggers while maintaining adequate nutrition. It is crucial to work with a gastroenterologist and a registered dietitian throughout this process to ensure nutritional needs are met and the reintroduction of foods is managed correctly.

Types of Elimination Diets for EoE

The most common dietary therapies for EoE are elimination diets, where food allergens are removed systematically and then reintroduced one by one under clinical supervision. The three main types are the Six-Food, Four-Food, and Two-Food Elimination Diets.

The Six-Food Elimination Diet (SFED)

The Six-Food Elimination Diet (SFED) is a comprehensive "top-down" approach that removes the six most common food allergens: milk, wheat, egg, soy, nuts, and fish/shellfish. Patients follow this diet for about 6 to 12 weeks, after which an endoscopy with biopsies is performed to check for remission. If the esophagus has healed, foods are reintroduced one at a time, with an endoscopy after each new food to see if it causes a relapse of inflammation.

Foods to Eliminate: Cow's milk and dairy products, wheat-based grains, eggs, soy products, all tree nuts and peanuts, and all fish and shellfish.
Pros: Highly effective, with studies showing remission rates of around 70% in both adults and children.
Cons: Highly restrictive, difficult to adhere to, and requires multiple endoscopies, making it a demanding process.

The Step-Up Elimination Diet (2-4-6 Approach)

A less restrictive and often preferred approach is the "step-up" diet, which begins by eliminating only the most common trigger foods and adds more restrictions if necessary. This method can reduce the number of endoscopies needed to find a patient's specific triggers.

Step 1 (2FED): Eliminate milk and wheat/gluten. This step alone can achieve remission for a significant number of patients, as these are the two most common triggers.
Step 2 (4FED): If no remission is seen after 6–8 weeks, expand the diet to eliminate egg and soy.
Step 3 (6FED): If a patient still does not respond, the diet is further restricted to also eliminate nuts and fish/shellfish.
Pros: Less restrictive at the start, easier adherence, and potentially fewer endoscopies.
Cons: Can be more time-consuming if multiple steps are needed to find the trigger foods.

The Elemental Diet

The elemental diet is the most restrictive but most effective treatment, especially for severe or refractory EoE cases. This approach removes all intact food proteins, and patients consume only an amino acid-based formula for at least 6 weeks.

How it works: Because all food protein is removed, this diet eliminates nearly all potential triggers. It can lead to histologic remission in over 90% of patients.
Pros: Extremely high efficacy, leading to rapid disease remission.
Cons: Poor taste, high cost, and severely limited dietary variety. This option is typically reserved for patients who fail other dietary or medical therapies.

Comparison of EoE Dietary Therapies


Feature	Six-Food Elimination Diet (SFED)	Step-Up Diet (2-4-6)	Elemental Diet
Restrictiveness	High	Low to High	Very High (Liquid Formula Only)
Effectiveness (Remission)	~70%	Starts lower, increases to ~79%	>90%
Patient Adherence	Often Challenging	Generally better than SFED	Very Low for Most Adults
Endoscopies Needed	Multiple (one for each reintroduced food)	Fewer initially, but can increase	Multiple, especially during reintroduction
Common Use Case	Highly motivated patients or those who have failed less restrictive diets	First-line approach for most patients	Severe, refractory EoE; young children with feeding issues
Cost	Moderate (alternative foods)	Low to Moderate	High (specialty formulas)

Key Considerations for Following an EoE Diet

Successfully managing EoE through diet requires more than just knowing what to avoid. Here are some critical points to keep in mind:

Nutrient Deficiencies: Restrictive diets, especially SFED, can lead to potential deficiencies in vitamins and minerals like calcium, vitamin D, and B vitamins. A dietitian can help monitor and supplement these nutrients.
Reading Labels: A cornerstone of a successful elimination diet is meticulously reading food labels. Familiarize yourself with all the names for your trigger foods. For example, be aware of milk derivatives like casein or whey, and soy ingredients like miso or edamame.
Cross-Contamination: Take precautions against cross-contamination at home and when dining out. Use separate cooking utensils and surfaces, and be cautious with bulk bins or buffets.
Psychosocial Impact: Living with a restrictive diet can affect social interactions and mental health. Consulting a dietitian or therapist can help manage the psychosocial burden of eating differently.
Individualization: The best diet is ultimately the one that a patient and their family can successfully adhere to. What works for one person might not be suitable for another, emphasizing the importance of shared decision-making with a healthcare team.

Conclusion: Finding the Right Path for You

What is the best diet for people with EoE is a question with no single answer; rather, it depends on individual factors. While the elemental diet is the most effective, its restrictiveness makes it a last resort for most. The step-up approach, beginning with the Two-Food Elimination Diet, is a practical and less demanding starting point for many. For those who can commit, the Six-Food Elimination Diet offers a high chance of remission but requires significant effort. No matter the path chosen, close collaboration with a healthcare team, including a gastroenterologist and a registered dietitian, is paramount to ensure safety, nutritional completeness, and long-term success. Understanding the options and making an informed, shared decision with your doctor is the most effective strategy for managing EoE through diet.

Frequently Asked Questions

EoE is a non-IgE mediated food allergy, which means that the inflammatory response is delayed and not detected by traditional skin-prick or blood tests. A standard allergy diet often removes foods based on these tests, whereas an EoE diet relies on systematically eliminating common triggers and reintroducing them to see which ones cause a relapse, confirmed by endoscopy.

The duration of the process depends on the type of diet you begin with. Starting with a Six-Food Elimination Diet and reintroducing foods one by one can take several months, as each reintroduction period is followed by an endoscopy. A step-up approach can reduce this time if remission is achieved early.

Elemental diets are highly effective for inducing remission but are not a first-line or ideal long-term solution due to their high cost, poor palatability, and social isolation. They are usually reserved for severe or refractory cases and managed carefully with medical supervision to avoid nutritional deficiencies and promote eventual oral feeding.

Eating out can be challenging but is possible with careful planning. Always call ahead to ask about ingredients and preparation methods. Explain your allergies clearly to the restaurant staff and request that your food be prepared separately to avoid cross-contamination from shared surfaces or utensils.

The most common food triggers for EoE in both adults and children are cow's milk and wheat. Other common triggers include soy, egg, peanuts, tree nuts, and fish/shellfish.

Symptoms alone are not a reliable indicator of active inflammation in EoE. An endoscopy with esophageal biopsies is the only way to accurately confirm if a food has caused a relapse of inflammation, showing an increased number of eosinophils in the esophageal tissue.

If you accidentally ingest a known trigger food, it's important not to panic. Symptoms may appear delayed, so it is recommended to keep a detailed record of your symptoms and inform your doctor or dietitian. Re-establishing the elimination protocol is the standard course of action.

No, EoE can also be managed with medication, such as proton pump inhibitors (PPIs) and swallowed topical steroids. Many patients and doctors choose a dietary approach as it addresses the root cause of the inflammation, but the best approach depends on the individual patient's needs and preferences.
