Vitamin D
Vitamin D is a helper for eczema, not a switch: Nielsen 2024's pooled analysis saw a small drop in severity scores, while an earlier Cochrane review judged the evidence insufficient for established eczema. Topping up a deficiency makes sense, but expecting vitamin D alone to control the chain of skin-barrier failure and allergic (Th2) inflammation asks more than the evidence can carry.

Starting solids
Eczema is the strongest early-life risk factor for food allergy. In the dual-allergen exposure hypothesis, broken skin lets food proteins in and triggers sensitization, while eating them on time helps the immune system learn tolerance. So babies with eczema especially should not have peanut put off; they should start it early with a doctor's guidance, after a doctor's assessment if the eczema is severe.

What eczema is

EVIDENCEREVIEW 1

READ THE ORIGINAL

Atopic dermatitis is the most common kind of eczema. It starts with a skin barrier that cannot hold water: water escapes outward, irritants and allergens push inward, and the immune response then tilts toward the allergy-type inflammation called type-2 (Th2) inflammation. It is not unwashed skin, and slightly dry skin is not eczema.

Itch is the core symptom, and it is often worse at night. Flares and quiet spells alternate, so one round of cream does not end it. Infants mostly get it on the cheeks and scalp; children and adults get it in skin folds such as the inner elbows and the backs of the knees. It often travels with asthma and allergic rhinitis, but it is not a disease caused by eating, and cutting out one food will not cure it.

One situation cannot wait: if crops of small blisters or raw sores suddenly appear on eczema skin, together with fever or feeling unwell, a herpes virus may have infected the eczema (eczema herpeticum). Seek medical care immediately.
