How long exclusion diet

Specific protocols may vary from patient to patient and practice to practice. In my practice, I usually have patients eliminate individual foods for a period of eight days. Some protocols go beyond this — for up to weeks at a time.

During the elimination period, we observe whether removing the food is helping resolve the symptoms that brought the patient to me in the first place.

Most often, foods are removed from the diet one at a time. But occasionally in people who are experiencing allergy symptoms like total body hives that require steroid treatment, many foods are eliminated all at once. I most often use an at-home challenge for patients who experience less severe food allergy symptoms like digestive discomfort, mild hives, or rashes.

An elimination diet may also be used as a form of treatment. Similarly, people with certain conditions, such as eosinophilic esophagitis EOE , might be prescribed an elimination diet that removes some of the most common food allergens as part of their treatment, which might be reintroduced as part of a challenge in the future, after medical treatment.

Why do we recommend medically-supervised elimination diets when food allergy testing is available? Because food allergy and sensitivity testing is both art and science. In my opinion, an elimination diet and oral food challenge is the only way to truly confirm a certain food is the problem unless the patient has an intense allergic reaction any time the item is consumed, for example, they have anaphylactic reactions to peanuts.

IgE blood tests are the main method of food allergy testing, along with IgE skin prick testing. These tests measure the presence of immunoglobulin E antibodies , which indicate an immune system reaction to a given substance. These tests are very helpful and can tell us a lot about the foods a person may or may not be allergic to, which you can read about in my complete guide to food allergy testing.

Sometimes IgE tests will come up positive for a food the patient has never had a reaction to. For example, shrimp and dust mites have a protein in common that some people are allergic to. Other common cross reactions include cashews and pistachios, and walnuts and pecans. The combination usually includes at least a detailed medical history, laboratory testing, a guided elimination diet, and an oral food challenge.

Also, before I do food allergy testing, I always tell my patients not to be surprised if it comes back negative. They might also be allergic to something other than food. An elimination diet and oral food challenge can help fill any gaps left by the food allergy test results, and can also help prove that the blood or skin prick test results are correct.

In fact, sometimes you can figure out what the problem food is through elimination and reintroduction alone. Still, I usually use elimination diets and food allergy testing in combination, as both the test and diet results can guide which foods should be eliminated and challenged next.

For me, the first step is getting the patient involved in the process, and getting them on board with working together to find answers through an elimination diet. Committing to the process is key. After you've fully committed to doing an elimination diet, the next step is to keep a thorough and detailed food diary for two weeks. When I say detailed, I mean really detailed. Do the crackers you just ate contain eggs, dairy, and soy, on top of wheat? Are there garlic and onions in the flavorings of foods that make you ill?

Milk, for example, is found in food where you might not expect it like baked goods, crackers, and candy. I usually comb through the food diary with my patient and list out the 10 most common foods in their diet. I take the food allergy test results into account, then come up with a list of foods to eliminate and challenge in a systematic way. We start with the foods that are most likely, in my opinion , to be the problem, and work our way down to the foods that are less likely.

But your allergist or dietitian is trained to notice things in food diaries that the average person might not, so making this stage a collaborative process is key. For instance, some people may not know all the foods that contain dairy, wheat, and soy, since these ingredients are often present in foods you might not expect. But a person trained in elimination diets and who is skilled at food allergy diagnosis will know exactly what to look for and will be knowledgeable about which foods contain which ingredients.

This part is simple. Although an elimination diet is very restricting, there is still enough variety to make healthy and delicious meals. To stay motivated during this restrictive phase, try designing new recipes and experimenting with herbs and spices to add delicious flavor to your dishes. Although elimination diets are restricting, there are still plenty of food options to make healthy and delicious meals. Besides the traditional elimination diet described above, there are several other types of elimination diets.

There are many different types of elimination diets, including the low-FODMAPs diet, the few foods diet, the rare foods diet, fasting and more.

Eosinophilic esophagitis EE is a chronic condition where allergies trigger inflammation of the esophagus, the tube that delivers food from mouth to stomach.

People with EE have difficulty swallowing foods that are dry and dense, increasing their risk of choking. Many studies have shown that elimination diets are effective for improving symptoms of EE 10 , 11 , Studies have shown elimination diets may reduce symptoms of ADHD 13 , 14 , One analysis looked at 20 studies that restricted certain foods to improve ADHD symptoms.

For starters, elimination diets should only be followed for a short period of time, or between four and eight weeks. Following an elimination diet for longer is not recommended, as it could cause nutrient deficiencies as a result of eliminating certain food groups. Additionally, children and people with known or suspected allergies should only do an elimination diet under the supervision of a doctor.

Children are also more prone to severe reactions, like anaphylaxis, when reintroducing a food group. This is because their bodies can become extra sensitive to foods after avoiding them Elimination diets can reduce the intake of important nutrients if followed for too long. Children and people with known or suspected allergies should not follow an elimination diet unless supervised by their doctor.

However, elimination diets are not for everyone. Children should not try an elimination diet unless supervised by a doctor or dietitian.

After the initial detox period of a few days, many people feel more energy and clarity than ever during an elimination diet. Between stress, pollutants, chemicals in our food and water and other environmental stressors, modern society deals with a lot of inflammation.

Your inflammatory response is an important part of your immune system, and you need it to rally when necessary. You also need it to turn off when the work is done. If your immune system stays engaged long-term, you have chronic inflammation. Over time, it can chip away at healthy cells and tissues until things have gone too far, and you end up with real damage.

Chronic inflammation can be subtle, to the point that it can be imperceptible to you. An elimination diet will reveal whether a food is contributing to chronic inflammation. When you bring food back, take notice of everything happening in your body and mind. All you need to do is pay attention. If you have a history of eating disorders, work with a physician before you try any restrictive diets.
