Alzheimer’s disease developed more frequently in French women - aged 76 to 84 – who were consuming less vitamin D in their diet, according to a study to be published soon from the Angers University Hospital Group. The association between vitamin D levels and preserved cognition has been noted before, but this is the first study to follow people prospectively and to assess their dietary vitamin D intake, aside from sun exposure. The women studied were not taking supplements, so their dietary sources would have been primarily fatty fish, also rich in omega-3 fatty acids. Vital Choice Seafood is an excellent source of the vitamin D rich fish.
Other whole food sources include egg yolks, liver, lard, and cheese.
Most people living outside of our equatorial zones need to supplement! For folks over 50 particularly, I recommend a liquid vitamin D3 supplement, taking enough to keep your levels 40-65 ng/mL, checked in the spring and fall.
