Vital Vitamins

Could the trick to staying sharp be found in the vitamin aisle?

This is Sandra Tsing Loh with the Loh Down on Science.

Dementia and diseases like Alzheimer’s impair memory and thinking for millions of people worldwide. Is there anything we can do to fight back?

Enter Maryam Ghahremani and team from the University of Calgary. They explored a possible solution found in. . . guess what? Food!

Researchers analyzed health and demographic data from over twelve thousand American adults spanning fifteen years. About forty percent of participants took vitamin D supplements. 

And? Adults who took vitamin D supplements were FORTY percent LESS likely to develop dementia! Researchers found that the vitamin was even MORE effective in women. However, people with a genetic predisposition for Alzheimer’s received LESS of the dementia-fighting benefit.

Consuming more vitamin D could be a simple way to prevent dementia! Think fish, milk, orange juice, and eggs!

I guess vitamin D stands for dementia-free! And if it’s chocolate milk, De-licious.
