A lack of vitamin D is being looked at as a cause of childhood allergies.
Researchers from the Murdoch Children’s Research Institute are examining whether vitamin D* supplements* could help prevent food allergies in infants and kids as part of a five-year study.
About one in 10 infants, and one in 20 children, suffer from food-related allergies in Australia, in what researchers say is a growing “allergy pandemic*.”
Associate Professor Kirsten Perrett said that given Australia already had the world’s highest rates of childhood food allergies, it was very important to stop any further rise.
“At this stage we have some hunches about why food allergy has been on the rise but we need to do these clinical trials to find out for sure,” she said.
“It’s a major, major issue for many Australians and we’re really wanting to turn back the tide to see if we can really make a difference.”
About 3500 babies, aged 6-12 weeks, will take part in the study.
It will see parents give their child a “drop” of vitamin D every day for their first year of life.
They will then be given an allergy test at the end of the 12-month period to see if the child is allergy free.
First-time mum Kiandra Ward and baby Toby, 13 months, took part in the first stage of the study last year.
Ms Ward said she had “never really considered” allergies being an issue for Toby — who was born healthy — but she took part in the study because she was worried by the increase in allergy rates.
“I was personally interested because growing up there weren’t many kids with allergies and nowadays there are,” she said.
“Toby came up negative, which is great (but) some kids aren’t allowed to have muesli bars or peanut butter and the amount of people that have allergies or intolerance issues — you see them every day.”
Prof Perrett said the Melbourne-based study would allow researchers to look at a large cohort* of children to see if vitamin D could play a role in preventing food allergies.
Vitamin D helps control calcium levels in the blood. It is needed for strong bones and muscles and overall health.
Sunlight is the best natural source of vitamin D but it is the also the main cause of skin cancer. This means many people avoid exposing their skin to the sun but in doing so they can also risk not getting enough vitamin D.
Prof Perrett said peanut and tree nuts, milk and eggs, and fish and seafood allergies made up about 90 per cent of all food allergies.
“Vitamin D could be part of the puzzle that we might be able to put in place to prevent allergies in future children,” she said.
