FOOD SENSITIVITY VS FOOD ALLERGY

Food Sensitivity vs Food Allergy vs Intolerance

Food allergies, food sensitivities, and food intolerances are often confused — but they involve different immune mechanisms, different timelines, and very different levels of urgency. Here’s how to tell them apart.

Allergy: rapid IgE-mediated reactions that can be severe and require emergency care
Sensitivity: delayed IgG-mediated responses, often hours or days after eating
Intolerance: difficulty digesting a food (like lactose), usually non-immune

SIDE BY SIDE

How They Compare

Food Allergy (IgE)

Immediate onset — minutes to a couple of hours. Symptoms can include hives, swelling, or anaphylaxis. Diagnosed and managed by an allergist. Can be a medical emergency.

Food Sensitivity (IgG)

Delayed onset — hours to days. Symptoms are non-emergency: bloating, fatigue, headaches, skin changes, brain fog. Explored with IgG testing and structured elimination diets.

Food Intolerance (Digestive)

Usually caused by missing enzymes (like lactase for lactose). Symptoms are digestive and dose-dependent. Not an immune reaction at all.

COMMON QUESTIONS

Food Allergy vs Food Intolerance: FAQs

Quick, clear answers about food allergy, food intolerance, and where Pinnertest fits in.

What is the difference between food allergy and food intolerance?

A food allergy is an immune reaction (often IgE-mediated) that usually happens quickly and can be severe. A food intolerance is typically not an IgE allergy and often involves delayed, non-emergency symptoms that may be harder to connect to a specific food.

What are common symptoms of food intolerance?

Food intolerance symptoms can vary, but people commonly report bloating, digestive discomfort, fatigue, headaches, skin changes, or brain fog. Because symptoms can be delayed, many people use a structured plan to identify trigger foods.

Is Pinnertest a food allergy test?

No. Pinnertest is not a food allergy test and does not diagnose food allergy or any medical condition. If you suspect a food allergy, consult an allergist or qualified healthcare provider.

How do I use a food intolerance report?

Most people remove the identified foods for a period of time and then reintroduce them thoughtfully. If you remove an important food (for example, dairy), simply replace key nutrients (like calcium) with alternatives. You can explore our food intolerance test and our food sensitivity overview for more details.

Should I change medication based on a food sensitivity report?

No. Never start, stop, or change medication based only on a lab report. Always discuss results and any major dietary or treatment changes with a qualified healthcare provider.
