Coffee drinking is in the genes

Two genes have been identified that are thought to determine how much of a craving you have for coffee.
The gene can come in a high or low consumption variety and is directly linked to how quickly you metabolise coffee and how much you crave for more. "The point here is that the way we drink caffeine is not just random," says Dr Neil Caporaso of the National Cancer Institute.
Dr Caporaso along with colleagues from the Harvard School of Public Health and the University of North Carolina, reported these findings in the journal PLoS Genetics. Globally, caffeine is the most popular psychoactive substance, with 90 per cent of people in the world consuming some form of it.

I must have this gene... I've been drinking coffee since I was a kid and pretty much panic if there's a possibility that I'd have to go without it. LOL. I can also drink a full pot of coffee and go right to sleep, no problem... it never really makes me jittery, nervous or high strung. *shrug* I've never thought it was a tolerance to caffiene though--2 cans of soda (even diet) has the potential to make me jumpy. I know in coffee, the caffiene is natural, in soda it's an additive. I'm wondering if there's a processing issue with caffiene-added products that affects me differently. Interesting. I... [More]

Oh yeah, definitely have this gene. Given the caffeine linkage and that it also exists in chocolate, well that just explains everything then doesn't it. Chocolate mmmmm, Mocca mmmmmmmmmmmmmm. I don't know if you drink it black, with or without sugar or have milk in it or not. But try with just a little bit of chocolate powder in it. I drink coffee with milk and little chocolate in it and I love it.

Stimulants like Caffeine can have a biochemical advantage on us, but some genes in a percentage of people made them more prone to addiction or chemical dependency than most. Genes itself can make a person dependent on a daily fix of a certain amount of caffeine among other compounds (i.e. alcohol or nicotine) to remain active. Without the given stimulant, our bodies start to become anxious or nervous in a manic personality...or grow tired inable to have a stance of energy without it. I been on 3 to 4 cups of coffee daily since after high school and 2 or 3 cans of caffeinated soda in a day when... [More]

My genes are running at full steam. I have a Senseo coffee machine in my office and drink 2 - 3 cups/day maybe 4 if I'm stressed. Long live coffee!

I'm a tea drinker. Don't care for coffee very much and only have one mug a day in the evenings, decaff and made with all milk. It's more of a habit really and apart from that I could quite easily live without coffee.
