Very important news about Vitamin D


#1

So don’t ever skip on it.


#2

They discovered that adults in the study who were moderately deficient in vitamin D had a 53 per cent increased risk of developing dementia

I hate articles like this. They state an increased risk as a percentage but never tell you what the initial risk was.

If the risk of getting dementia is .0001 to begin with than a 53% increase is still very small.


#3

this study found that people with very low vitamin D levels were more than twice as likely to develop any kind of dementia.


#4

How likely were they to develop dementia in the first place?

From the article

Dementia is one of the greatest challenges of our time, with 44 million cases worldwide – a number expected to triple by 2050 as a result of rapid population aging. A billion people worldwide are thought to have low vitamin D levels and many older adults may experience poorer health as a result.

I don’t have hard numbers, but I can extrapolate from the above. Start with earths population of about 7 billion. Say that those at an age susceptible to dementia make up the oldest 20% of the population, which gives 1.4 billion. Assuming all those 44 million are of that 1.4 billion, that’s 44/1400 = 0.0314, or 3.14%. 3 out of 100. My guess of 20% may be off, and the 44 million likely includes younger cases as well, but it’s close enough to show it’s not a negligible risk.

Edit: Looking at world age distribution, 20% oldest is an age of 50-55 and older.
