New research provides further evidence to suggest
that sufficient vitamin D while pregnant can have health benefits for future
children, with a recent Australian study suggesting that the vitamin could help
prevent autism traits in offspring.
Autism – or autism spectrum disorder – is a
lifelong condition where sufferers experience developmental disabilities such
as an inability to communicate with others, interact socially, or fully
comprehend the world.
In their animal study, a team of researchers from
the University of Queensl
and’s Queensland Brain Institute used the most widely
accepted developmental model of autism, in which the mice behaved abnormally
and demonstrated problems with social interaction and basic learning, an online
report said Monday.
The team of researchers gave the pregnant mice
active vitamin D supplements, a nd found that pregnant females treated with
active vitamin D in the equivalent of the first trimester of pregnancy produced
offspring that did not develop autism deficits.
The discovery provides further evidence of the
crucial role vitamin D plays in brain development, said lead researcher
Professor Darryl Eyles, with the results also backing up QBI’s other recent human
studies on the effect of vitamin D on autism.
QBI’s 2016 study carried out with the Erasmus
Medical Centre in The Netherlands looked at blood samples from 4229 pregnant
women and found that those who had low vitamin D levels at 20 weeks’ gestation
were more likely to have a child with autistic traits by the age of six,
suggesting a link between low vitamin D and brain growth and neurodevelopmental
disorders.
However commenting on the results of the new
study, researcher Dr Wei Luan also pointed out that although vitamin D is
crucial for health, including maintaining healthy bones, the active hormonal
form of vitamin D cannot be given to pregnant women because it may affect the
skeleton of the developing fetus.
However, he also added that, “Recent funding will
now allow us to determine how much cholecalciferol – the supplement form that
is safe for pregnant women — is needed to achieve the same levels of active
hormonal vitamin D in the bloodstream.”
Vitamin is produced by skin cells when exposed to
sunlight, however it can also be found in some foods including oily fish
(salmon, trout, tuna, sardines and mackerel), calf’s liver, soy and egg yolks.
The results can be found published online in the
journal Molecular Autism.
