How To Complete An Elimination Diet Suited To You

What is an elimination diet?

Elimination diets are commonly used tools in functional medicine. The food we eat is the foundation of our wellness yet, some foods, even seemingly healthy ones, may triggers unwanted symptoms in some people. It is estimated that between 2–20% of people worldwide may suffer from some form of a food intolerance. An elimination diet is the process of removing a food or group of foods from a person’s diet for a set period of time. The absence of the food(s) and then careful reintroduction of the item(s) helps determine whether specific foods or ingredients in foods contribute to unwanted symptoms. Elimination diets are individualized based on each patient’s history, eating patterns, and overall symptom picture.

Why complete an elimination diet?

Food sensitivities can be responsible for a variety of symptoms. You may benefit from completing an elimination diet if you struggled with any of the following symptoms:

 

Bloating
Heartburn
Distention
Constipation
Diarrhea

Fatigue
Difficulty sleeping
Skin rashes
Headaches
Low mood

 

Common types of elimination diets:

  • FODMAP Diet: This diet eliminates foods high in certain carbohydrates (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) that can be difficult to digest and may cause digestive symptoms such as bloating, gas, and diarrhea. It is often used to manage irritable bowel syndrome (IBS) or other functional gastrointestinal disorders.

  • Gluten-Free Diet: This diet eliminates all sources of gluten, a protein found in wheat, barley, rye, and some other grains. It is necessary for individuals with celiac disease, an autoimmune disorder triggered by gluten, and may also be followed by those with non-celiac gluten sensitivity.

  • Dairy-Free Diet: This diet eliminates all dairy products, including milk, cheese, yogurt, and butter. It is commonly followed by individuals with lactose intolerance, a condition in which the body has difficulty digesting lactose, the sugar found in dairy products. It may also be followed by individuals with milk protein allergies.

  • Specific Carbohydrate Diet (SCD): This diet eliminates complex carbohydrates, disaccharides, and certain grains. It is often used to manage digestive disorders such as Crohn's disease, ulcerative colitis, and celiac disease.

  • Low-Histamine Diet: This diet restricts foods that are high in histamine or release histamine in the body. It is followed by individuals with histamine intolerance, a condition characterized by an inability to properly break down histamine, leading to symptoms such as headaches, flushing, hives, nasal congestion and digestive issues.

  • Whole30: Whole30 is a 30-day elimination diet that removes grains, legumes, dairy, added sugars, processed foods, and certain food additives. It is designed to reset eating habits, identify food sensitivities, and promote overall health and well-being. It is not specifically designed for a particular health condition.

  • Autoimmune Protocol (AIP) Diet: The AIP diet eliminates foods that may trigger inflammation and exacerbate autoimmune conditions. It eliminates grains, legumes, dairy, eggs, nightshade vegetables, nuts, seeds, refined sugars, and processed foods. The AIP diet is often recommended for individuals with autoimmune diseases who are looking to manage their symptoms and reduce inflammation. It eliminates potential trigger foods to support immune system regulation.

  • Six Food Elimination Diet: This diet is often used in the diagnosis of food allergies in children. It helps identify specific allergenic foods that may be causing symptoms such as skin rashes, digestive issues, or respiratory problems. It eliminates the most common allergenic foods, including milk, eggs, peanuts/tree nuts, soy, and wheat.

These are just a few examples of elimination diets, and there may be variations or combinations of these diets based on individual needs and specific health conditions. It's important to consult with a healthcare professional or registered dietitian before starting an elimination diet to ensure proper guidance and monitoring throughout the process.

What to expect on an elimination diet:

  • Duration of the Diet: During the elimination phase, you will remove certain foods from your diet based on the specific type of elimination diet you are following. This phase typically lasts for a few weeks to several months, depending on the diet and your individual needs.

  • Potential Withdrawal Symptoms: Some people may experience withdrawal symptoms when cutting out certain foods, particularly those containing caffeine or sugar. These symptoms can include headaches, irritability, and fatigue. These effects should subside after a few days as your body adjusts.

  • Improved Symptoms: If you have food sensitivities or intolerances, you may notice a reduction in symptoms during the elimination phase. For example, digestive issues, skin problems, or respiratory symptoms may improve as you remove trigger foods.

  • Food Reintroduction: After the elimination phase, you will start reintroducing the eliminated foods one at a time in a systematic manner. This is usually done over several weeks, and each food is reintroduced individually, allowing you to observe any reactions.

  • Identification of Food Sensitivities: The primary goal of an elimination diet is to identify any food sensitivities or intolerances. By reintroducing foods one by one, you can pinpoint which ones are causing adverse reactions.

  • Increased Awareness of Eating Habits: Elimination diets often require careful reading of food labels and increased awareness of ingredients. This can lead to improved knowledge about the foods you consume and better eating habits.

  • Emotional Challenges: Elimination diets can be challenging, especially if you have to give up favorite foods or make significant dietary changes. This might cause some emotional ups and downs during the process.

  • Support and Guidance: Having a healthcare professional or registered dietitian guide you through the elimination diet can be highly beneficial. They can help you plan your meals, monitor your progress, and provide support throughout the process.

  • Reintroduction Reactions: Some individuals may experience reactions when reintroducing certain foods. These reactions could be mild or more severe, depending on the level of sensitivity. If you experience severe reactions, it's essential to stop consuming the food and consult with a healthcare professional.

Is there a blood test to use instead of completing an elimination diet?

There are many lab tests availalve that measure certain antibodies or biomarkers in the blood that are associated with an immune response to specific foods. They claim to identify which foods might be triggering adverse reactions in individuals. However, food sensitivity tests have many challenges including lack of standardization, difficulty interpreting the significance of IgG antibodies and potential cross-reactions between foods. Food sensitivities are complex and can involve various immune mechanisms. Blood tests often oversimplify the process by focusing on just a few markers, potentially missing other important factors.

Due to these limitations, many healthcare professionals and experts still consider elimination diets as the gold standard for identifying food sensitivities or intolerances. Elimination diets allow for a more comprehensive and personalized approach, and they are more likely to provide accurate results in identifying specific trigger foods.

If you are considering food sensitivity testing, it's crucial to consult with a qualified healthcare professional who can help you understand the limitations and implications of the test results. They can also guide you on the most appropriate approach to identifying and managing potential food sensitivities based on your unique health needs and history.
