The latest medical news for people with allergies and food sensitivities
Classroom chalk containing casein can trigger respiratory symptoms in milk-allergic children, say researchers from the Hospital Marina Baixa in Spain. They studied a group of 12 milk-allergic children and found that all were sensitized to the chalk (allergy testing was positive). In four of the children, the chalk dust triggered wheezing, coughing and sneezing. Symptoms improved when the chalk was switched to a brand that didnt contain casein.
