Receiving your YorkTest food intolerance results is a major first step toward understanding your body’s unique responses to food. But the real transformation begins with how you use that information. Knowing which foods your immune system reacts to (via raised IgG antibodies) is helpful—but what you do next can make the difference between short-term improvement and lasting health gains.
This guide walks you through the process of using your YorkTest results to create a healthier, more energised version of your diet—starting with elimination, and moving mindfully into reintroduction.
Step 1: Understand Your Results
When your results arrive, they’ll clearly show which foods triggered elevated IgG antibody responses, often labelled as red (high reactivity) or amber (borderline). These results are unique to you and reflect how your immune system is currently responding to specific foods—not necessarily permanent allergies, but sensitivities that may be reversible.
Common reactive categories include:
- Dairy (milk, cheese, yoghurt)
- Grains (wheat, barley, rye)
- Eggs
- Yeast
- Fruits or vegetables (e.g. citrus, tomato, onion)
Tip: Book your included nutritional therapist consultation to help interpret your results and build an elimination plan tailored to your needs and lifestyle.
Step 2: Begin the Elimination Phase (4–6 Weeks)
This phase involves removing all foods flagged as reactive in your YorkTest results. While it may sound restrictive, it’s designed to reduce inflammation, improve digestion, and allow your body to reset.
How to do it:
- Eliminate all red and amber foods for at least 4 weeks
- Replace them with low-reactive or non-reactive alternatives
- Plan meals ahead to avoid slip-ups and reduce stress
Tools to help:
- YorkTest provides sample meal ideas and food swaps
- Use apps or a food diary to track meals and symptoms
- Look for “free-from” versions of favourites in supermarkets (e.g. gluten-free oats, dairy-free milks)
Common benefits noticed during elimination:
- Reduced bloating and digestive discomfort
- More stable energy and better focus
- Improved skin clarity
- Fewer headaches and mood swings
Step 3: Mindful Reintroduction (1–2 Weeks per Food)
After the elimination phase, it’s time to carefully reintroduce foods one at a time, monitoring for any return of symptoms. This process helps determine which sensitivities may have been temporary, and which are best avoided longer term.
How to reintroduce:
- Start with one previously eliminated food
- Eat it in normal quantity once a day for 3 days
- Watch for reactions such as bloating, fatigue, brain fog, skin flare-ups, or sleep changes
- If no reaction occurs, consider reintroducing it into your diet gradually
- If symptoms return, remove the food again and test another after a few days
Tip: Keep a symptom tracker or food journal to stay objective and organised.
Step 4: Build Your New, Personalised Diet
With your reactive foods identified and tested, you’ll begin to form a new normal—a diet that supports your energy, digestion, and wellbeing.
What this might look like:
- Using plant-based milks instead of dairy
- Switching to gluten-free grains like rice, quinoa, or buckwheat
- Discovering new protein sources, spices, or cooking techniques
- Creating a rotation system so you avoid overexposure to any one food
The goal isn’t restriction—it’s long-term resilience and enjoyment of food that your body thrives on.
Step 5: Stay Flexible and Reassess Periodically
Food intolerances can change over time, especially if they were linked to stress, gut health, or overconsumption. After a few months of your new diet, you may find you can tolerate certain foods again.
YorkTest recommends:
- Continuing to observe your body’s signals
- Repeating the test annually if symptoms reappear
- Staying proactive with gut health and stress management, which influence food reactions
Final Thoughts
Using your YorkTest results to guide a personal dietary transformation isn’t about restriction—it’s about listening to your body, resetting your system, and creating a way of eating that works with, not against, your health.
With the right elimination and reintroduction plan, backed by expert support, you can go from confused and reactive to confident and in control.
