How many cups of coffee do you drink each day? Does caffeine affect you differently than your friend who can only drink a half cup before bouncing off the walls?
Researchers may have discovered why: caffeine consumption genes. A study published in PLoS Geneticsthat included researchers from Harvard School of Public Health and the National Cancer Institute reports to have found two genetic variations that influence caffeine metabolism. These genes may also be associated with how much caffeine people consume.
After reading this study, I'm pretty sure that I fall into the category of those with the high consumption gene variation because they're more likely to consume caffeine, and to drink more of it when they do. The theory is that their bodies metabolize caffeine faster so it takes more of it to reach a desirable level.
