"Researchers at St George Hospital this year will undertake what is said to be the world's largest study of vitamin D levels in pregnant mothers and their newborn.
The study, which will test 1000 women and their babies over the next six months, aims to track the rate of vitamin D deficiencies in dark-skinned women compared with the broader population.
Dark-skin races did not photoactivate vitamin D as well as lighter-skinned people, and they released less vitamin D into breast milk, he said."
