Itchy eczema may trigger the development of food allergies in infants.
Researchers studied 619 exclusively breastfed infants, which allowed them to rule out allergic responses emerging via the gut. About 25% of the infants had eczema and 5.5% were sensitized to 1 of the 6 studied foods—egg, cow’s milk, peanut, wheat, codfish, and sesame—that cause the most frequent allergic reactions. Using skin prick testing, the researchers found babies with eczema were 6 times more likely to be sensitized to egg, milk, peanut, and wheat. There was no association between eczema and codfish or sesame.
