A recent study has revealed a strong link between a deficiency of vitamin D and various forms of dementia including Alzheimer's disease. Per the article:
People with moderate-to-severe vitamin D deficiencies are significantly more likely to develop Alzheimer’s disease or other forms of dementia than those who have an adequate supply of the vitamin in their body, a new study has found. Researchers, led by David J. Llewellyn at the University of Exeter Medical School, found that adults who suffered from a moderate deficiency of vitamin D had a 53 percent higher risk of some form of dementia, while the risk increased 125 percent in those with severe deficiencies. People moderately deficient in vitamin D were 69 percent more likely to develop Alzheimer’s-caused dementia, while those severely deficient raised the risk to 122 percent.
Thanks for posting, John. Vitamin D has been linked to almost anything lately: I wonder if it's a sort of hype. We need it anyway, so let's try to find what works and what doesn't!
Another study linked vitamin D deficiency to aggressive prostate cancer.
For years, until maybe a year ago, I looked for but found no Vitamin D in grocery stores.
I asked around and heard too much was thought harmful so it was taken off the shelves.
Did a recent dementia surge cause the change?
5,000 IU of vitamin D per day is safe and helps to prevent cancer too.
