Quick answer: After the elimination and reintroduction phases, the maintenance phase helps you build a long-term way of eating around what you learned. Focus on whole foods, quality protein, low-glycemic carbohydrates and healthy fats, avoid your confirmed triggers, moderate caffeine and alcohol, stay hydrated, and reassess as your body changes.
Key takeaways
After the elimination diet, the goal is a sustainable, nourishing diet built around what you learned about your triggers.
A personalized whole-food diet reflects your genetics, environment and lifestyle.
Continuing to notice how foods make you feel helps you keep the widest possible variety of foods over time.
Congratulations
You’ve identified your food triggers and learned a lot about your body. Now the goal is a sustainable, nourishing diet. Overview: what is the elimination diet.
A functional medicine view of nutrition
A personalized, whole-foods diet that reflects your genetics, environment and lifestyle.
Key principles
Prioritize whole foods such as proteins, vegetables, fruit, nuts and seeds, and healthy fats, and choose quality protein such as grass-fed meat, wild-caught fish and free-range poultry. Favor low-glycemic carbs like leafy greens, cruciferous vegetables and berries, and include healthy fats such as avocado, olive oil, nuts and seeds.
Avoid confirmed triggers to limit inflammation, moderate caffeine and alcohol, and stay hydrated. Above all, adjust as needed as your body changes.
Mindfulness and long-term success
Keep noticing how foods make you feel. Practical tips: managing food sensitivities.
Healthy aging lens
A varied, whole-food diet with enough protein can support muscle, steady blood sugar and lower inflammation as you age. See insulin sensitivity and aging.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have ongoing digestive, skin, headache or joint symptoms you suspect are food-related, or if you want to try an elimination diet safely. The same is true if you have a medical condition, are pregnant, or have a history of disordered eating, or if symptoms persist after an elimination diet.
See a medical provider promptly for hives, swelling of the lips or throat, trouble breathing, or dizziness after eating. These can be signs of a serious allergic reaction; call 911.
