A recent study has shown that children with asthma have scarily-similar symptoms to a peanut-sensitivity.
The lead author, Dr. Robert Cohn at Mercy Children's Hospital in Toledo, Ohio says that if a child's asthma symptoms like wheezing and coughing are becoming or are already severe, the parents may want to consider testing the child for food sensitivities, like peanut.
Records of over 1,500 children were analyzed and researchers found that 1 in 10 children had a peanut sensitivity. However, roughly half of these families had no suspicion that their child had this. Cohn has reported to sources that this may be do to the similar symptoms of asthma and a peanut allergy, and suggests that having a peanut allergy could actually make a child's asthma worse.
This study, like many others, is a stepping stone toward more scientific answers surrounding food allergies and sensitivities. However, like ALL studies, this just shows that there is always more to know about the topic.
When it comes to your child or loved one, if you suspect that they have a food allergy or intolerance always talk to your family doctor and suggest an antibody test to find out.
