Coffee is a chemical juggernaut, quickly absorbed and distributed throughout the body, affecting everything from brainpower and eyesight to digestion and bowel function. However you take yours – cold brew, espresso, pour-over or plunged – coffee affects your entire system.
“A single cup of coffee has rapid absorption with caffeine uptake to the blood in just over 20 minutes and will stay in the blood stream for over 12 hours,” says Dr Owen Bain, founder of the Gourmet Focus consultancy.
Pulse and blood pressure
Shortly after drinking coffee, your blood pressure rises a fraction – the effect is more pronounced if you don’t drink coffee regularly. If you stick to one cup, your heart rate actually slows down due to the increase in blood pressure. “However, more than a few cups of coffee can cause heart rate acceleration,” Dr Bain says. For healthy people this is not a problem, but may be an issue for those with underlying problems such as heart disease, high blood pressure or abnormal heart rate, according to some experts.
Ordering an espresso after a meal makes a certain physiological sense – caffeine raises acid levels in your stomach, which facilitate digestion. But experts advise avoiding coffee on an empty stomach as the gastric juices can irritate the gut lining, causing pain, bloating and heartburn.
