Complex food, chemical, supplement and medication sensitivity
For shrinking diets and growing reaction lists, where each new restriction buys less relief than the last.
This page is for people whose safe list has been shrinking for years. Foods that were fine become reactive, supplements provoke responses their ingredients do not explain, fragrance and cleaning products trigger symptoms, and every elimination round produces a smaller diet without a more stable body. The analytical goal is to explain why the threshold keeps dropping, because restriction alone rarely changes that.
What records in this area tend to contain
These are descriptions of records, not diagnostic criteria. Recognising several of them does not mean you have a condition, and none of them is being asserted about you.
- A reaction list that grows faster than any single intolerance can explain
- Histamine-type, salicylate-type, or oxalate-type frameworks tried in sequence
- Reactions to excipients, fillers, or coatings rather than active ingredients
- Autonomic features accompanying food reactions — palpitations, flushing, lightheadedness
- Nutritional consequences of prolonged restriction now complicating the picture
- Improvement during elimination followed by re-narrowing within weeks
The analytical work on a case like this
- Structured reaction inventory across foods, excipients, medications and environments
- Whether the pattern fits a chemical class, a mediator threshold, or neither
- Gut barrier, microbial, and enzymatic contributions the record can speak to
- Autonomic and mast-cell overlap, since both alter perceived and actual reactivity
- Nutritional adequacy and refeeding considerations, flagged for your clinicians
- What each prior elimination trial demonstrated, including the ones read as failures
What the work is trying to answer
These are the questions the reconstruction is built around. They are questions, not promises — some records answer them clearly and some do not, and the written synthesis says which.
- Is this a set of distinct intolerances, or one threshold problem expressing itself through many triggers?
- Which reactions are reproducible under conditions the record can verify?
- What is the nutritional cost of the current pattern, and who should be reviewing it?
- What would a clinician-supervised reintroduction question look like if the leading reading is right?
What would argue against the leading reading
Every synthesis states the alternatives it could not exclude. For this area, the most important ones are:
- Coeliac disease or a true IgE allergy that has not been excluded properly
- Fructose, lactose, or FODMAP malabsorption accounting for much of the food list
- Eating-related anxiety and conditioned aversion, which coexist with real physiology
- Medication or supplement side effects being read as sensitivity
- Micronutrient deficiency from restriction, now generating symptoms of its own
Nothing here is dietary treatment, a prescription for elimination, or advice to remove foods. Restriction carries real nutritional risk and belongs under the supervision of a physician or registered dietitian. BiomeLogic does not diagnose allergy, coeliac disease, or any food-related condition.
