Link Between Vitamin D And Women's Cognitive Performance

Supports Chapter 11:  Our irrational fear of sunlight

As part of the concept of a 'healthy' lifestyle foisted on us in the 1980s, sunbathing became a no-no, unless you were fully clothed, or slathered in sunscreen, or the sun wasn't shining, or preferably all three! 

Not long after, the numbers of cases of Alzheimer's dementia began to rise. Today, in the UK at least, dementia has become the number one health concern, not just for the misery it causes to sufferers and their families, but the sheer cost in terms of both money and health resources needed to look after the growing number of people with dementia.

And so to December 2012:

Two new studies have just been published in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences which show that vitamin D may be a vital component for the cognitive health of women as they age.

Higher vitamin D dietary intake is associated with a lower risk of developing Alzheimer's, according to research conducted by a team led by Cedric Annweiler, MD, PhD, at the Angers University Hospital in France.

Similarly, investigators led by Yelena Slinin, MD, MS, at the VA Medical Center in Minneapolis found that low vitamin D levels among older women are associated with higher odds of global cognitive impairment and a higher risk of global cognitive decline.

Slinin's group based its analysis on 6,257 community-dwelling older women who had vitamin D levels measured during the Study of Osteopathic Fractures and whose cognitive function was tested by the Mini-Mental State Examination and/or Trail Making Test Part B.

Very low levels of vitamin D (less than 10 nanograms per milliliter of blood serum) among older women were associated with higher odds of global cognitive impairment at baseline, and low vitamin D levels (less than 20 nanograms per milliliter) among cognitively-impaired women were associated with a higher risk of incident global cognitive decline, as measured by performance on the Mini-Mental State Examination.

Annweieler's team's findings were based on data from 498 community-dwelling women who participated in the Toulouse cohort of the Epidemiology of Osteoporosis study.

Among this population, women who developed Alzheimer's disease had lower baseline vitamin D intakes (an average of 50.3 micrograms per week) than those who developed other dementias (an average of 63.6 micrograms per week) or no dementia at all (an average of 59.0 micrograms per week).

Another case of 'cause and effect', as a result of incompetent health advisers.

In view of the enormous costs to the NHS relating to Alzheimers and associated diseases it would probably be cheaper for the government to send us oldies on Pensioners' Jollidays to the Canaries for a fortnight each winter!
Do you think Cameron et al would fall for it?

Hello Peter

You are almost certainly right about the possible financial savings.

But that said, I winter in the Canaries (that's where I am now, and iy's warm, quiet and peaceful). I hate to think what it would be like if the UK shipped all everyone who was 'away with the fairies', as my sister-in-law's doctor calls them, were sent here. :-)

Hello Barry,

You are most likely familiar with the WUWT website, the world's most viewed climate website.

There is an interesting post by David Archibold, who before he started out in climate science in 2006,co-invented a cancer drug with two professors from Purdue University, Professor Jim Morre and his wife Professor Dorothy Morre. He went on to lodge a patent on a benign prostatic hyperplasia (BPH) drug.

In 1998, David was given the draft manuscript of a book on how isoflavones from soy and other legumes modulate the human female hormone system.


All the best,

Another article has appeared in the Daily mail today on the benefits of vitamin D in prevention of various diseases . All very commendable but probably next week there will be an article citing a link between cancer and vitamin D.It's no wonder people are so very confused about it all. Also the information given is very limited. For instance, ' Sunbathing is good for you' doesn't tell the whole story. Time and place is crucial as is topical skin product...............or rather lack of product. A little knowledge is a dangerous thing. I'd advise anyone to forget the 'health pages' of the morning papers and get a .........book or better still , several books by different authors which cover the desired subject thoroughly and hopefully impartially.

You can certainly see your skills in the article you write. The world hopes for even more passionate writers like you who are not afraid to say how they believe.
