More Caffeine, Thanks Mom
The color of your eyes, the color of your hair and the shape of your nose are all things someone can thank genetics for. And according to the National Cancer Institute, you can now say ‘thanks’ to Mom and Dad for the amount of caffeine you intake.
The amount of caffeine a person craves can be found in two genes in the human body. The specific genes are labeled CYP1A2 and AHR. The CYP1A2 gene is connected with the process of how our body uses caffeine, and AHR is in charge of regulating the CYP1A2 gene.
People usually think of only characteristics someone can see when they think of family genetics. However, genetic epidemiologists at the National Cancer Institute say genetics also plays a part in behaviors such as the amount of alcohol someone drinks, smoking and the cravings for caffeine.
