A new study by an international team of researchers shows that the amount of coffee you drink each day may be determined by your genes. The amount you need to feel that caffeine buzz — and potentially to enjoy it — can depend on your DNA.
The discoveries provide insight on why caffeine affects people differently, and how these effects influence coffee-drinking behavior. One person, for example, may feel energized on a daily cup of coffee, while another might need four cups to feel the same effect. If the one- cup - a- day person consumes four cups, he or she might feel jittery or experience digestive issues, discouraging that level of consumption going forward.
