Depending on your CYP1A2 genotype, caffeine can either increase or decrease your risk of high blood pressure and heart disease. In another study, fast metabolisers aged less than 60 years had a lower risk of heart attack, compared to fast metabolisers who didn’t drink coffee. Moderate coffee drinkers with this genotype have a 72% higher risk of high blood pressure than those with the same genotype who don’t drink coffee. A study published in the journal JAMA about slow caffeine metabolisers provides further insight into this group. The participants, who were slow caffeine metabolisers, increased their risk of heart attack by 36% if they drank two to three cups of coffee daily.
