Elimination Diet

Before you delve into it first, you have to ask yourself, what is the elimination diet? Simply put, a food elimination diet is a strategy for testing a person’s food sensitivities.


There are many types and variations of elimination diets. The basic ones are based on eliminating gluten and dairy for a few weeks, but others are stricter. Generally, elimination diets aim to avoid common foods known to cause sensitivities and then reintroduce them into the diet one after the other. The aim is to identify whether certain trigger foods cause inflammation, headaches, skin issues, and other side effects (3).

Understanding Food Allergy Vs. Intolerance

Although sometimes used interchangeably, food intolerance is not the same thing as an allergy. The two phenomena may present similar symptoms, thus making them easy to mix up. Having an allergy means that your body’s immune system reacts to the food, which can be acutely life-threatening. On the other hand, food intolerance arises from a sensitivity or trouble with digesting a particular food.

Note that severe food allergies are not something you can self-diagnose or even ignore. In cases where you suspect having an allergy, you should see a certified allergist immediately so that the issue is diagnosed and the best course of action is taken (6).

Should You Try An Elimination Diet?

As indicated earlier, before you commit yourself to an elimination diet, you should first explore whether you are suffering from an allergy or food intolerance.

If you are experiencing headaches, constipation, fatigue, heartburn, bloating, or trouble swallowing, you may have a food intolerance. It is typical for such symptoms to worsen 1 to 3 hours after taking a meal. In most cases, the timing makes it difficult to know whether the diet or something else is causing the problem.

Those suspecting they may be having an allergy may undergo blood and skin tests. However, such a diagnosis may not always provide the answer to your question. In such a case, a doctor will have to recommend a food challenge to confirm food sensitivity (5).

A food challenge is whereby a doctor administers small portions of the possible food trigger and then observes you for the symptoms. This is believed to be the best practice when diagnosing allergies.

To establish food intolerance, you can use an elimination diet. This is achieved by taking out a group of foods from your diet for a specified duration and then reintroduce them one by one to determine the ones that are causing you to react. For best results, you ought to do this under the guidance of an allergist.

  • Elimination Diet: Get Creative With Your Recipes

An elimination diet may sound as if you will only be eating salad after salad making it sound uninteresting. However, there is always room to be inventive and come up with delicious recipes. For instance, many egg-free or gluten-free breads are not as tasty as wheat-based ones. However, you can still bake your bread with whole-grain and a range of different ingredients to make it more appealing (7).

  • Remember To Rotate

You may find a particular type of food you like that fits your restrictions and be tempted to eat it over and over again. It does not matter if it is only the elimination diet breakfast. If you want to achieve optimal health, then there is no option other than rotating. Develop a three-to-four-rotation plan which will have a minimum of three different breakfast, lunch, and dinner ideas.

  • Elimination Diet: Stay Hydrated

Sometimes people tend to eat unnecessarily because they mistake thirst for hunger. To avoid this, develop a habit of drinking plenty of water during the diet and beyond it.

  • Pace Yourself

During the phase where you start to reintroduce foods, you may be tempted to splurge on things like ice cream and pizza. The only way you will know the particular ingredient causing your symptoms is by re-introducing each food individually. Set reminders to reintroduce specific foods, so they do not coincide, and ensure that they are spaced out by several days.

  • Consult A Professional

There should be no compromise when it comes to professional guidance. Remember that elimination diets are not only complicated, but they can also be very challenging. Due to the many roadblocks in implementing the diet, many people fail to achieve the results they are looking for. The professional will be there to walk you through the challenges to complete the elimination diet as intended (1).

How To Do An Elimination Diet?

Before starting an elimination diet, develop a food and symptom diary, which will help identify the connection between eating habits and symptoms. From there, it will be easier to know which foods you should try to eliminate.

Implementation of an elimination diet is made possible by having a plan in place. There are many variations of an elimination diet plan, with some being full while others are partial. In a complete elimination diet plan, one has to take out more than eight foods from the diet simultaneously. It may be cumbersome or even challenging to adjust to eliminating so many foods instantly. This can also deprive the body of useful nutrients.

The most preferred plans are those that only eliminate three or four foods at a time for three weeks. The 21 days are enough for you to notice any changes in your symptoms. After 21 days, you will be feeling better only if you have found the right trigger. It is at this stage that you start to reintroduce the eliminated foods one after the other. There ought to be a window of at least three days after introducing a food to assess the body’s reaction to the food before trying another one (3).

If you show no symptoms after adding all the foods, you proceed to the next step of the plan to eliminate another group of foods. Continue repeating the process until you find a food that causes the symptoms. That will be the trigger you have been looking for.

Naturally, You Will Stop The Elimination Diet At That Point

However, there may be a chance that there is more than one food at fault. It is advisable to continue with the plan, but this time, start by eliminating the most common offenders and then move to the less common ones.

You should consult with your doctor during each phase of the plan and practice extreme caution with packaged foods by going through the labels to find out if they contain ingredients you are trying to avoid. If you are eating out, inquire from restaurant staff about your dish’s contents before you eat.

If you are worried about the risk of going hungry when avoiding some foods, that should not be a concern. In case you are feeling hungry, you can always eat things like fruits, vegetables, or even healthy fats like coconut and avocado (10).

Benefits Of An Elimination Diet

Apart from helping you identify the foods that cause you uncomfortable symptoms, an elimination diet has several other benefits, including (2):

  • It May Reduce Symptoms Of Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a common gut disorder that affects close to 10-15% of people worldwide. The elimination diet has been shown to improve IBS symptoms like bloating, stomach cramps, and gas.

  • May Help With Eosinophilic Esophagitis

This is a chronic condition in which allergies trigger inflammation of the esophagus- the tube through which food moves from the mouth to the stomach. This makes it challenging to swallow dense and dry foods, thereby causing the risk of choking. The elimination diet comes in handy by improving the symptoms of this condition (4).

  • Reduction Of ADHD Symptoms

Attention-deficit/hyperactivity disorder (ADHD) is a behavioral disorder that affects both children and adults. Elimination diets have the potential to reduce the symptoms of this disorder. It reduces symptoms, especially among people who are sensitive to foods. Children should not be put on an elimination diet without the supervision of a medical practitioner.

  • Improvement Of Skin Conditions Like Eczema

Skin conditions like Eczema make the skin appear red, inflamed, cracked, and itchy. Many different things cause such situations, but a certain food consumption can worsen the symptoms associated with them. It is for that reason that elimination diets can reduce the symptoms of conditions like Eczema (11).

  • Reduction Of Chronic Migraines

Millions and millions of people from all over the world suffer from chronic migraines. While the exact cause of migraines is unclear, inflammation is believed to be one of the triggers. In this case, an elimination diet will remove those foods that cause inflammation, thus reducing migraines.

Are There Any Risks Associated With Elimination Diets?

Sometimes you may find yourself asking questions such as, why am I so tired on an elimination diet? Well, you ought to be prepared for a few risks when you go down this route. Some of these risks are:

  • It is advisable to adopt an elimination diet only for a short period that is eight weeks or less. Following the diet for a longer period than that could result in nutrient deficiencies due to the obvious reason that you have eliminated certain food groups (2).
  • Children should only be put on an elimination diet under the supervision of a doctor. Eliminating food groups even for a short duration of time could end up stunting a child’s growth.
  • Children are also at a higher risk of having severe reactions such as anaphylaxis during the plan’s reintroduction phase.

The Bottom Line

The first thing that comes to most people’s minds when a diet is mentioned is weight loss. This is not the case with an elimination diet. It is a meal plan that removes certain foods to establish what you are sensitive or allergic to. Before you adopt such a diet, please consult your doctor to ensure it is the best course of action to take. Children should not be put on such a diet because it deprives them of essential nutrients necessary for their growth.
