Every body is different — and yours has a story.
The foods you eat and the environments you spend time in show up in your body in quietly personal ways. What feels wonderful for one person may leave someone else feeling bloated, foggy or stuffy. The Food & Environmental Sensitivity Test is an educational tool designed to help you notice patterns worth paying attention to — so you can make more intentional nutrition and lifestyle decisions.
Three different things, often confused.
Language matters. Understanding the difference between an allergy, a sensitivity and an intolerance helps you use this test — and any elimination plan — responsibly.
Food Allergy
A true immune response.
- Involves IgE antibodies and the immune system
- Can cause severe or life-threatening reactions
- Requires medical diagnosis and management
- Not what this test is designed to evaluate
Food Sensitivity
A more subtle pattern.
- May contribute to delayed or less obvious symptoms
- Often explored through elimination and reintroduction
- Highly individual — varies from person to person
- Educational — does not replace medical evaluation
Food Intolerance
A digestive story.
- Often related to enzyme or digestive challenges
- Classic examples include lactose intolerance
- Symptoms are typically digestive in nature
- Different mechanism than an allergy or sensitivity
The Food & Environmental Sensitivity Test is not intended to diagnose food allergies. Anyone with symptoms suggestive of an allergic reaction should seek evaluation from an appropriate healthcare professional.
Small daily inputs, meaningful daily outputs.
Food and environmental exposures can affect overall comfort differently from person to person. Sensitivities aren't a proven cause of every symptom — but recognizing potential patterns can be an empowering next step.
Digestive Discomfort
Some people notice bloating, gas or occasional stomach upset in response to specific foods.
Skin Irritation
For certain individuals, skin flare-ups, dryness or breakouts feel tied to what they eat or their surroundings.
Congestion
Environmental exposures like pollen, dust or mold can leave some people feeling stuffy or foggy.
Occasional Fatigue
Everyday triggers may contribute to feeling drained, even after a full night of sleep.
Headaches
Recurring headaches are complex — but food and environmental patterns are sometimes part of the picture.
Individual Variability
Two people can eat the same meal or share the same space and feel completely different afterwards.
The categories your report gently explores.
The Food & Environmental Sensitivity Test evaluates a wide spectrum of everyday foods and food-related ingredients. Identifying potential patterns may help guide a structured elimination-and-reintroduction plan.
Dairy
Milk, cheese, yogurt and dairy-derived ingredients found throughout the modern pantry.
Grains
Wheat, oats, corn, rice and other grains that anchor countless everyday meals.
Proteins
Common animal and plant proteins — including beef, poultry, eggs and legumes.

“Sensitivity testing is a starting point, not a verdict. The real insight comes from listening to your body as you thoughtfully eliminate and reintroduce.”
— Dr. Tammy Sinclair
A short, structured learning experiment.
An elimination diet is a short-term educational tool for exploring how your body responds. It works best when it's intentional, time-limited and ideally supported by a healthcare professional.
This information is educational and not a substitute for medical advice. Always consult a qualified healthcare provider before making significant changes to your diet — especially if you're pregnant, nursing, managing a health condition or supporting a child.
One Group at a Time
Focus on one food category so you can more clearly notice how each change feels.
Track Consistently
Keep a simple daily journal of foods, exposures, energy, digestion, mood and sleep.
Reintroduce Methodically
Bring foods back one at a time, spaced out, and watch for any patterns you notice.
Avoid Long Restriction
Elimination is a short educational tool — not a permanent, overly restrictive lifestyle.
Loop in a Professional
Work with a healthcare provider or registered dietitian when appropriate, especially for complex symptoms.
Stay Nutritionally Balanced
Keep meals colorful, satisfying and nutrient-dense throughout every phase of the process.
