Friday, January 16th — Coffee

Today I Learned…

…about a bunch of things that coffee can do besides keep you awake!  (Thanks to slashdot.)

First of all, coffee has been shown to reduce risk of Alzheimer’s disease and dementia A team Swedish and Finnish scientists kept tabs on the coffee habits of over 1,400 people over the course of several decades.  Those who reported that they drank between three and five cups of coffee a day during middle-age were found to be 60-65% less likely to develop Alzheimer’s disease or dementia later in life.  It is unknown how exactly this protection comes about, but hypotheses center around the high levels of antioxidants in coffee and by lowering cholesterols which attack the blood-brain barrier.

However, don’t go all crazy with the java.  Another study has just come out from Durham University which has linked excessive caffeine intake to a higher risk of both audio and visual hallucinations.  This effect manifests itself at fairly high levels:

‘High caffeine users’ – those who consumed more than the equivalent of seven cups of instant coffee a day – were three times more likely to have heard a person’s voice when there was no one there compared with ‘low caffeine users’ who consumed less than the equivalent of one cup of instant coffee a day.

…so the fact that I just thought I heard my doorbell ring while my dog was barking is probably just the regular kind of crazy — I don’t drink quite that much coffee.

Oh, and also:
