Farm kids less likely to have asthma
A new discovery has found that kids who grow up on farms are less likely to develop asthma and have a bigger immunity to allergies than the average city slicker.
It's the kind of discovery that could completely change how we treat asthma in the future.
Nanotech scientist Michelle Dickinson joined Paul Henry this morning to explain how and why this is.
She says the study shows that farm dust in young children under the age of two can protect them from allergies later in life.
There's thought to be a link to cow manure somewhere along the line. The bacteria from manure dies and goes into the dust, which then creates a protein in your lungs called A20. This then stops the mucus membrane in your lungs reacting with the allergy.
