Food has a profound impact on our health, influencing everything from digestion and inflammation to energy levels and mental clarity. But for many, certain foods can trigger unwanted symptoms without them even realizing it. An Elimination Diet is a structured approach to identifying food sensitivities and intolerances by removing common trigger foods for a period of time, then systematically reintroducing them to observe how the body reacts. This process helps uncover the root causes of symptoms and allows for a more personalized, nourishing diet. As we begin the third month in our 12 Gifts of Health Journey—Step #3: Remove food sensitivities—this aligns with the third foundational step in the "Remove and Replace" phase of healing: eliminating foods that trigger an immune response in your body. By taking this step, you create space for deep healing and a diet that truly supports your well-being.

Why Follow an Elimination Diet?

Unlike food allergies, which cause an immediate immune reaction, food sensitivities often create delayed or chronic symptoms that can be difficult to pinpoint. These reactions may manifest as digestive distress, fatigue, joint pain, brain fog, migraines, skin conditions, sinus congestion, or autoimmune flare-ups. By eliminating potential triggers and allowing the body to reset, an elimination diet can reduce inflammation, improve digestion, increase energy levels, and restore balance.

The goal of nourishing yourself for optimal health isn’t about restricting as many foods as possible, but rather about creating a diverse, nutrient-rich diet that supports health and longevity. However, the paradox is that true healing can be difficult when your immune system is constantly reacting to the foods you consume every day. If your body is in a state of nutrient deficiencies, your gut microbiome is out of balance, and your stress levels are chronically high, you may find yourself reacting to many foods. This is why removing trigger foods is an essential step in the healing process.

As you work to restore gut health, replete essential nutrients, and manage stress, your body becomes more resilient, and food sensitivities often decrease. Over time, you may find that you react to only one or two foods—or possibly none at all. By focusing on removing trigger foods while prioritizing a nutrient-dense, whole-foods approach, you’re laying the foundation for greater food freedom and long-term well-being.

Finding the Right Elimination Diet for Your Health Journey

There are many types of Elimination Diets, each designed to help identify food sensitivities, reduce inflammation, and support healing based on individual needs. The Basic Elimination Diet removes common triggers like gluten, dairy, soy, eggs, corn, and yeast to uncover hidden intolerances. The Full Elimination Diet removes all of the common trigger foods, plus citrus, chocolate, beef, pork, tree nuts, sesame, and cane sugar. The Anti-Inflammatory Diet focuses on eliminating inflammatory foods while emphasizing nutrient-dense, whole foods that support gut and immune health. The Six Food Elimination Diet (SFED) is often used for eosinophilic esophagitis (EoE) and removes the top six allergens: dairy, wheat, soy, eggs, nuts, and seafood. The IFM Elimination Diet, developed by the Institute for Functional Medicine, is a structured approach that removes common inflammatory foods and supports detoxification with whole, healing foods. The Autoimmune Protocol (AIP) takes elimination a step further by removing grains, legumes, nightshades, nuts, and seeds to calm autoimmune flare-ups and promote gut healing.

The Low-FODMAP Diet is specifically designed to reduce symptoms of irritable bowel syndrome (IBS) and other digestive disorders by eliminating fermentable carbohydrates that can cause bloating, gas, and discomfort. The Low-Oxalate Diet is beneficial for those sensitive to oxalates, found in foods like spinach, almonds, and sweet potatoes, which can contribute to kidney stones and inflammation. The Low-Histamine Diet helps manage histamine intolerance by avoiding aged, fermented, and high-histamine foods that can trigger symptoms like headaches, hives, and digestive distress. No matter your health journey, finding the right Elimination Diet can be a powerful tool for discovering what foods work best for your body and achieving optimal wellness.

Foods Commonly Eliminated and Their Associated Symptoms

An Elimination Diet removes foods that are known to cause sensitivities, intolerances, or inflammatory reactions. Below are the food groups eliminated in different elimination diets and the symptoms they may trigger:

1. Gluten (Wheat, Barley, Rye, Spelt)

• Symptoms: Bloating, gas, diarrhea, constipation, brain fog, headaches, joint pain, skin rashes, and autoimmune reactions (e.g., Hashimoto’s, Celiac disease).

2. Dairy (Milk, Cheese, Yogurt, Butter)

• Symptoms: Congestion, sinus issues, bloating, acne, eczema, joint pain, and digestive distress.

3. Lactose (Milk Sugar Found in Dairy)

• Symptoms: Gas, bloating, cramping, and diarrhea due to an inability to properly digest lactose.

4. Corn (Corn Syrup, Corn Starch, Cornmeal)

• Symptoms: Digestive issues, skin reactions, joint pain, and fatigue, which also can include GMO-related sensitivities or cross-reactions with gluten.

5. Soy (Soybeans, Tofu, Tempeh, Soy Milk, Edamame, Soy Sauce)

• Symptoms: Bloating, digestive upset, and skin breakouts.

6. Eggs (Egg Whites & Yolks)

• Symptoms: Skin rashes, digestive issues, bloating, fatigue, and joint inflammation. Egg whites contain proteins that can trigger immune responses in sensitive individuals.

7. Tree Nuts (Almonds, Cashews, Walnuts, Pecans, Pistachios)

• Symptoms: Skin reactions, bloating, sinus congestion, headaches, and digestive distress.

8. Yeast (Saccharomyces Cerevisiae: Baker’s Yeast, Brewer’s Yeast, Nutritional Yeast)

• Symptoms: Skin rashes, digestive issues, bloating, brain fog, fatigue, and headaches. Yeast overgrowth (Candida) can exacerbate these symptoms, and some individuals with autoimmune conditions may have an immune reaction to yeast proteins.

9. Chocolate (Cacao, Cocoa Powder, Dark Chocolate, Milk Chocolate)

• Symptoms: Migraines, acid reflux, skin breakouts, digestive upset, and nervous system overstimulation due to caffeine, theobromine, or histamine content. Those with histamine intolerance or oxalate sensitivity may be particularly reactive to chocolate.

10. Citrus (Oranges, Lemons, Limes, Grapefruits, Tangerines)

• Symptoms: Acid reflux, heartburn, mouth sores, skin rashes, headaches, and histamine-related reactions. Some individuals with mast cell activation syndrome (MCAS) or histamine intolerance may react negatively to citrus fruits.

11. Nightshade Vegetables (Tomatoes, Peppers, Eggplants, Potatoes)

• Symptoms: Joint pain, inflammation, skin issues, digestive upset, and autoimmune flares due to their alkaloid content, which may aggravate inflammatory pathways.

12. Beef

• Symptoms: Migraines, joint pain, and fatigue, particularly in those with sensitivities to red meat proteins or high histamine levels found in aged red meat.

13. Pork

• Symptoms: Digestive discomfort, bloating, gallbladder disease, constipation, inflammation, joint pain, skin reactions, and fatigue. Pork can be high in inflammatory fats and histamines, which may trigger symptoms in sensitive individuals, especially those with autoimmune conditions or histamine intolerance.

14. High-Histamine Foods (Aged Cheeses, Fermented Foods, Vinegar, Alcohol, Smoked Meats, Spinach, Tomatoes, Eggplant)

• Symptoms: Migraines, skin flushing, itching, nasal congestion, anxiety, and digestive discomfort, particularly in individuals with histamine intolerance or mast cell activation issues.

15. High-FODMAP Foods (Garlic, Onions, Apples, Legumes, Wheat, Cherries)

• Symptoms: Gas, bloating, diarrhea, cramping, and IBS-like symptoms due to poor digestion of fermentable carbohydrates (FODMAPs). Chronic Fatigue Syndrome and fibromyalgia are often associated with bacterial overgrowth. A low-FODMAP diet has been shown to greatly reduce symptoms associated with these conditions. 

16. High-Oxalate Foods (Spinach, Beets, Almonds, Sweet Potatoes, Chocolate, Peanuts)

• Symptoms: Kidney stones, joint pain, inflammation, digestive discomfort, and urinary irritation in individuals sensitive to oxalates. The low-oxalate diet is also used for those with Crohn's disease as this autoimmune condition can cause increased absorption of oxalates due to fat malabsorption and calcium saponification with fats in the gut.

How to Follow an Elimination Diet:

1. Elimination Phase (4 to 6 Weeks)

• Remove all trigger foods for a minimum of four weeks, allowing the body time to clear inflammatory responses and reset.
• Focus on nutrient-dense, whole foods like fresh vegetables, fruits, high-quality proteins, healthy fats, and gluten-free grains like quinoa and rice (if applicable to your diet).
• Keep meals simple, and drink plenty of water to support detoxification.

2. Reintroduction Phase (One Food at a Time)

• After 4 to 6 weeks, reintroduce one eliminated food at a time, eating it three times a day for three days while tracking symptoms.
• If no symptoms appear, the food is likely safe to eat.
• If symptoms return, remove the food again, wait until symptoms calm down, and then continue with other reintroductions.
• This process helps pinpoint exactly which foods trigger symptoms, allowing for a more personalized diet.
• Note: In The Elimination Diet book, some foods can be reintroduced after just two weeks. Foods that are less likely to cause reactions, such as citrus, are introduced earlier in the process, while common trigger foods are reintroduced later to allow more time for healing.
