Allergy and immune care
13 guides written only from verified guidelines, trials and FDA labels. Each one gives the general evidence and how strong it is; decisions about one person's care stay with that person and their clinician.
Food allergy
What food allergy is, how labels work, and which foods travel together.
Food allergy: the basics
What researchers mean by a food allergy, how often it is real, what can look like one, and what studies report about outgrowing it.
Reading food labels
What US law requires a label to say, what precautionary statements do and do not mean, and what studies show about how little of an allergen can cause a reaction.
Cross-reactivity
Why an allergy to one food or pollen can bring reactions to related foods, and where research finds that this is common and where it is rare.
Testing
What allergy tests can and cannot show.
Emergencies
Anaphylaxis, epinephrine, and what every guideline puts first.
Environmental allergy
Pollen, dust mite, pets and mold.
Prevention
What the trials found about feeding babies allergenic foods.
Treatment
Treatments that change the allergy itself.
Immune conditions
Eczema, hives and mast cells, FPIES, EoE and alpha-gal.
Hives, mast cells and MCAS
What hives are, why an antihistamine label says it does not prevent them, and what experts say about mast cell activation syndrome.
Eczema and the atopic march
What eczema is, why it is tied to food allergy and asthma, whether moisturizing a baby's skin prevents it, and which treatments the evidence supports.
FPIES
What food protein-induced enterocolitis syndrome is, how it differs from a typical food allergy, how common it is, and what studies report about outgrowing it.
Eosinophilic esophagitis (EoE)
A chronic immune disease of the esophagus, how guidelines define it, and the treatments they recommend.
Alpha-gal syndrome
Why reactions to beef, pork or lamb can come hours after a meal, the role of ticks, and the mammal products beyond meat that can be involved.
Epitope Allergy Care
At-home testing, a video visit with a licensed clinician, and immunotherapy shipped monthly when it fits.
