Is Your Coffee Habit Inherited?
You think that you drink coffee because you like the taste and aroma or because it wakes you up in the morning and keeps you going all day. Is that true? Maybe, as an article in the Los Angeles Times suggests, your coffee habit may be written in your DNA.
Scientists have been studying the genetics behind coffee cravings since the 1960s. In 1962, they found that coffee-drinking habits appeared to be hereditary. More recently, large-scale studies have found an association between the amount of coffee people consume and a small handful of genes.
The authors report that among more than 1,200 people living in Italy, those with the genetic variant PDSS2 tend to drink one fewer cups of coffee per day than those without the variation.
Further analysis revealed that expression of the PDSS2 gene appears to inhibit the body’s ability to break down caffeine. If that’s the case, people with this variant would require less coffee to get a strong caffeine jolt because the caffeine would linger in their system for a longer time.
So it turns out that some folks need less coffee to keep going because they do not metabolize it as fast as the rest of us. If you are one of the folks who drink six cups a day it may just be that your system is breaking down and excreting your coffee faster that other folks. If that is your case blame your parents who passed on that trait.

What we do not know is if those
folks who require less coffee
because they break it down faster
still get the benefits of coffee
consumption, namely a reduced
chance of dying in the next few
years, less Alzheimer’s and
Parkinson’s diseases and the rest.
