An article about coffee in Scientific American is believable.
"That morning coffee is just the thing to get the brain in gear and the body moving. But it turns out that just the aroma of coffee also gets some of our genes up and at ‘em. That’s according to research in the June 25th issue of the Journal of Agricultural and Food Chemistry. The authors report that a sniff of coffee turns on several genes in the brain in ways that help diminish the impact of sleep deprivation. In rats, at least. "
..."Rats that were stressed by lack of sleep were exposed to the smell of coffee. Seventeen different genes got activated in their brains. And thirteen of them produced proteins known to protect nerve cells from the damaging effects of stress. While there have been numerous studies analyzing the health impact of the ingredients ingested when drinking coffee, the researchers say that this is the first study to examine the effects of coffee’s aroma."
I really like the smell of coffee. The coffee beans. The coffee brewing. The coffee in the cup. So, hey, if it is good for the rats it's got to be good for me too. Getting my brain in gear is good too, but the scents and senses are happy campers in our house.
