What is an Elimination Diet?

by Md Assaduzzaman

An elimination diet is a methodical approach to identify foods that may cause adverse reactions in your body. It's a two-phase process involving the removal of foods that are common triggers of allergic reactions, GI distress, headaches, and other symptoms. After a period, you reintroduce certain foods slowly, one-at-a-time to help pinpoint sensitivities in your diet. You may discover you are sensitive to a particular food, or a particular ingredient in a commonly eaten food. Studies have found that an elimination diet can improve immunity and resistance to a variety of symptoms triggered by common allergens (1). 

Elimination Diet Basics

1. Make a List and Remove Potential Triggers:

    • Common culprits include dairy, gluten, nuts, soy, eggs, and certain fruits and vegetables. Some people are allergic to uncommon fruits like mangos, papayas, tomatos and bananas. 
    • Eliminate all suspected foods from your diet for a set period, typically 2-6 weeks.

2. Reintroduce Foods Slowly:

    • Introduce one-food-at-a-time back into your diet.
    • Monitor your body's reaction carefully, noting any symptoms like fatigue, bloating, headaches, or skin issues.
    • This phase helps identify specific food intolerances by isolating which foods trigger symptoms.

3. The Health Benefits?

    • Identify Food Sensitivities: With an elimination diet, you can discover inexpensively those foods that are most problematic. 
    • Pinpoint problem foods that may cause digestive issues, skin conditions, or other health problems.
    • Helps in developing a sustainable, long-term eating plan free from problematic foods.
    • Improve Overall Health:
    • Better digestion and reduced bloating.
    • Clearer skin and fewer headaches.
    • May reduce chronic inflammation and improve energy levels.
    • Personalized Nutrition:
    • Tailored diet based on individual responses to foods.
    • Encourages mindful eating and better food choices.


Elimination diets can be a powerful tool for uncovering food sensitivities and improving overall well-being. Testimonies around the internet can be found extolling the virtues of going on a simple diet. Not only will you discover new hidden ingredients you may be sensitive to, you also gain teh benefits of eating a minimally processed, diet. This is the principle behind other diet protocols, like the mono-fruit diet, where only one type of fruit is eaten at each meal.  

You also save time on cooking, preparing meals, and planningout your daily meals! Explore the benefits of an elimination diet to uncover how specific foods affect your body and enjoy a healthier, more personalized nutrition plan.
