A recent study concludes that not all children who are born with an intolerance to cow’s milk outgrow the intolerance and that they are at increased risk of other conditions. Researchers at the University of Palermo, Italy, reviewed the records of 38 children to collect data; 12 of those studied were intolerant of cow’s milk until at least age four, while the intolerance disappeared in the others by age two.
The study found that about 92% of children with persistent milk allergies also suffered from multiple other food allergies, compared to 12% of children who lost their intolerance to milk by age two. It was further found that 75% of those with persistent milk allergies suffered from other atopic conditions, including asthma, hayfever, and the skin condition eczema, compared to 8% of those who lost their milk intolerance early. The study is in the journal Clinical and Experimental Allergy.
