A little story about Australians and increased vitamin D levels
For decades Australians had been told that sunshine was deadly.
They avoided the sun, and some even used sunscreen 24 hours a day, during all seasons.
Then they noticed a big increase in a great many diseases.
The public thought that these increases might be due to low vitamin D from lack of sun.
The doctors said no, could not be, and the government would not even allow selling capsules containing more than 1000 IU
The public asked for vitamin D tests (about a 100X increase in 11 years)
The government then refused to pay for any more (unnecessary) vitamin D tests.
That did not stop the public - they took matter into their own hands.
Slight increase in Vitamin D levels (entire country increased vitamin D by 20X in a decade)
While the rest of the world had DECREASING levels of vitamin D
