Dietary Guide - Two Food Elimination Diet (2FED) for EoE

This document has been developed by ASCIA, the peak professional body of clinical immunology/allergy specialists in Australia and New Zealand.

Eosinophilic oesophagitis (EoE) happens when white blood cells (called eosinophils) build up in the lining of the oesophagus, which is the tube that connects the mouth to the stomach. This can be the result of an allergic reaction to food or the environment.

Most cases of EoE are seen in people with other allergies such as allergic rhinitis (hay fever) and asthma. It is estimated to affect around one in 1,000 people (children and adults), and the frequency of EoE appears to be increasing. The reasons are unclear, but it is known that allergies of all types have become more common.

More information about EoE can be found on the ASCIA website:

ASCIA PC Dietary Guide EoE 2FED 2023222.19 KB

The 2FED diet eliminates the two most common trigger foods for EoE – cow’s milk (dairy) and wheat

Diet Instructions

1. This diet plan outlines how to follow a diet free from cow’s milk (dairy) and wheat. The diet involves strictly avoiding all foods and drinks that contain cow’s milk (dairy) and wheat even in very small quantities.
2. This diet is to be used for 8 to 12 weeks as a trial to see if avoiding certain foods will help reduce symptoms. You should regard this diet as a test to see if foods are making symptoms worse and not necessarily a long term treatment.
3. You will be asked to complete diaries recording foods eaten and details of any symptoms whilst following this diet.
4. The effect of the diet will be assessed by symptoms and/or a repeat endoscopy (a procedure to look inside the body with a small tube with a camera and light attached), and biopsies (samples of cells) of the oesphagus are taken.
5. Each food will then be reintroduced one by one. Introduction of foods will be discussed in detail by the doctor and dietitian at follow up appointments.

What foods can be eaten?

If you have existing food allergies it is important to continue to avoid those foods whilst following this diet for EoE. Otherwise, all plain meat, fish, chicken, egg, legumes, non-wheat grains, fruits, nuts, seeds and vegetables can be included. Your specialist may recommend excluding all gluten containing grains (wheat, barley, rye and oats).

What about packaged foods?

Many packaged food products will contain ingredients made from wheat or milk. In Australia and New Zealand, food manufacturers must declare the presence of any cow’s (and other animal) milk (dairy), wheat and other gluten containing grains however small the amount. It is important to check package labels, including ingredients lists carefully, and avoid products with any of the ingredients in the following tables.

What are “may contain traces of” statements?

These statements are voluntary and used by manufacturers to indicate that the product may be contaminated with food allergen ingredients through processing and packaging. Products that do not directly contain cow’s milk (dairy) or wheat as an ingredient but have a “may contain ______” style statement are safe to include on this diet.

Cow’s milk protein

The following foods and ingredients contain cow’s milk protein and should be avoided:

Note: Other animal milks such as goat, sheep, camel, buffalo products are too similar to cow’s milk (dairy) products, so they should not be used as substitutes. Check labels on all foods.

The following foods may contain cow’s milk protein unless the label says otherwise and need to be avoided:

Wheat

The following foods and ingredients contain wheat and should be avoided:

Check labels on the following foods to see if they contain wheat and if they do, avoid them:

Foods to include whilst following the 2FED diet for EoE

Ingredients listed in the table below do not contain cow’s milk or wheat proteins and are safe to eat whilst following the 2FED diet for EoE.

Cow’s milk (dairy) alternatives

Considerations for infants and young children

If your child will not drink the milk substitute, a dietitian can advise how to encourage your child to accept it, or how to supplement the diet with essential nutrients such as calcium, energy and protein.

It is important to have an adequate calcium intake, as recommended in the following table.

Recommended daily intakes of calcium

A calcium supplement may need to be taken if inadequate volumes of milk replacement or specialised formula are taken. Your dietitian will assess this and discuss this with you if required.

Wheat alternatives

The biggest challenge when avoiding wheat is finding alternative breads, cereals and pasta. The following table outlines some substitutes.
