The table implies for example that Alzheimer's is 164 times more prevalent in Finland than in Singapore. One would think that would be widely known, if true. There must be essentially zero Alzheimer's in Singapore if these stats are true.
Conversely, if these stats really are true, then they are very important!
You are right, looking at countries that have high and low rates of Alzheimer's can give very important information. Yes Singapore has very low rates of death from Alzheimer's and so does Malaysia. I have attached a table with those rates.
My husband recently looked at the Blue Zones as people there live longer and there are lower rates of dementia and Alzheimer's. In addition there is a great deal of information on these areas as they are well known and have been studied a lot. My husband after a great deal of research found the drinking water in all the Blue Zones is high in Silica due to the underlying geology of the areas. We were both very surprised by these findings. Each time he would go to research the next Blue Zone we would wonder will he be able to find the data and would there be high levels of silica in the drinking water. When he got to the last Blue Zone, Loma Linda I thought there was no way he would find high silica in the drinking water. Their drinking water is high in silica and one of the tenets of the 7th day Adventists religion is to drink 8 glasses of water a day.
Here are the 5 Blue Zones:
• Okinawa, Japan – The largest island in a subtropical archipelago that has the world’s longest lived women.
• Villagrande, Sardinia – A small mountainous region on an island off the coast of Italy with the world’s highest concentration of male centenarians.
• Ikaria, Greece – An island off the coast of Greece in the Aegean Sea that has one of the lowest rates of middle age mortality in the world and the lowest rate of dementia in the world.
• Nicoya Peninsula, Costa Rica – A region where residents have one of lowest rates of middle age mortality in the world and the second highest concentration of male centenarians.
• Loma Linda, California – City with the highest concentration of Seventh-day Adventists in the U.S.A. where they live ten years longer than the average American.
Regarding Finland there is a recent study 2017 titled Why does Finland have the highest dementia mortality rate? Environmental factors may be generalizable Arnold R.Eiser Mold was one of the things they looked at. This study didn't look at aluminum or silica water.
