Understanding the 6 Food Elimination Diet
The 6 food elimination diet, or 6FED, is a therapeutic dietary approach primarily used to manage symptoms of eosinophilic gastrointestinal disorders (EGIDs), such as Eosinophilic Esophagitis (EoE). It involves removing the six most common food allergens for a period of 4 to 8 weeks to allow the body to heal and symptoms to subside. The six allergens are:
- Milk and dairy products
- Soy and all soy-based products
- Eggs
- Wheat and gluten-containing grains
- Peanuts and tree nuts
- Fish and shellfish
After the initial elimination phase, foods are systematically reintroduced, one at a time, to identify which specific items trigger a reaction. This process should always be conducted under the guidance of a medical professional or registered dietitian.
Safe and Delicious Foods to Eat on 6FED
Despite the restrictive nature of the diet, there remains a wide range of nutritious and flavorful foods that are safe to eat. Focusing on naturally allergen-free, whole foods is key to success during the elimination phase.
Fruits and Vegetables
- All fresh, frozen, and canned fruits and vegetables are typically safe. This includes apples, bananas, berries, melons, leafy greens like spinach and kale, broccoli, cauliflower, carrots, and sweet potatoes.
- Note: Some highly sensitive individuals might need to avoid certain food families, but this is specific to individual cases.
Proteins
- Meat: Fresh, unprocessed cuts of chicken, turkey, beef, lamb, and pork are allowed. Grass-fed and organic options are often recommended.
- Legumes: Most legumes, excluding soy, are good protein sources. This includes black beans, lentils, chickpeas, and split peas.
- Protein Powders: Rice, hemp, or pea protein powders can be used as supplements.
Grains and Starches
- Gluten-Free Grains: Brown rice, quinoa, millet, amaranth, sorghum, buckwheat, and teff are excellent alternatives to wheat.
- Flours: Use flours made from allowed grains, such as rice flour, buckwheat flour, or chickpea flour.
- Starches: Potatoes and sweet potatoes are staples in many 6FED meal plans.
Fats and Oils
- Oils: Olive oil, avocado oil, and coconut oil are safe cooking options.
- Dairy-Free Butters: Look for dairy-free margarine and butter alternatives made from safe ingredients.
Seeds and Alternatives
- Seeds: Pumpkin, sunflower, chia, and flax seeds are excellent additions.
- Seed Butters: Sunflower seed butter (SunButter) and tahini (made from sesame seeds) are safe nut butter alternatives.
Navigating the Elimination Phase with a Comparison Table
It is crucial to be vigilant about ingredients, as many processed foods contain hidden allergens. A simple approach is to focus on preparing meals with whole foods and reading labels carefully.
| Food Category | Allowed Foods | Eliminated Foods |
|---|---|---|
| Dairy | Coconut milk, oat milk, hemp milk, dairy-free butter | Cow's milk, cheese, yogurt, whey, casein, butter |
| Soy | Coconut aminos, refined soybean oil | Tofu, tempeh, edamame, soy milk, soy sauce |
| Wheat | Rice, quinoa, buckwheat, gluten-free oats | Wheat flour, couscous, semolina, spelt, most bread |
| Eggs | Flax eggs, chia eggs, commercial egg replacers (check ingredients) | Whole eggs, egg whites, mayonnaise, custard |
| Nuts | Pumpkin seeds, sunflower seeds, coconut, pine nuts | Almonds, walnuts, peanuts, cashews, pistachios, nut butters |
| Fish/Shellfish | Safe proteins like chicken, beef, legumes | Salmon, tuna, crab, shrimp, lobster, fish sauce |
Sample 6FED Meal Ideas
With proper planning, meals can be varied and satisfying. Here are some examples:
- Breakfast: Oatmeal made with oat or coconut milk and topped with berries, sliced banana, and sunflower seed butter. A smoothie with hemp milk, spinach, blueberries, and a banana is another great option.
- Lunch: A large green salad with grilled chicken or chickpeas, black beans, cucumber, carrots, and a simple olive oil and lemon dressing. Leftover pot roast with roasted root vegetables can also be a filling choice.
- Dinner: Ground turkey stir-fry with brown rice and a variety of sautéed vegetables like broccoli and carrots, seasoned with coconut aminos. You could also have a flavorful pot roast with potatoes and green beans.
- Snacks: Fresh fruit, vegetable sticks with guacamole or hummus, rice cakes with sunflower seed butter, or homemade granola bars with safe ingredients.
The Reintroduction Phase: How it Works
After the elimination phase, you will work with your healthcare team to begin the reintroduction phase. This is the process of individually challenging each of the six food groups to see if any cause a return of symptoms.
- Introduce one food group at a time: Each food group is tested for a period, typically 1 to 2 weeks, while monitoring for any reactions.
- Monitor symptoms: Keeping a detailed food and symptom journal is essential during this phase. Some reactions can be delayed, so vigilance is key.
- Endoscopy: In the context of EoE, an endoscopy may be performed after each reintroduction period to check for inflammation.
- Confirming triggers: If a food group causes a return of symptoms or inflammation, it is identified as a trigger and removed from the diet permanently.
Conclusion
The 6 food elimination diet is a highly effective tool for managing allergic conditions like EoE by systematically identifying and removing specific food triggers. By focusing on a diverse range of naturally safe foods like fresh fruits, vegetables, lean proteins, and gluten-free grains, a nutritious and satisfying diet is achievable during the elimination phase. Following the protocol carefully, with the support of a healthcare professional, leads to a better understanding of individual triggers and a more personalized, effective long-term management plan.
