For those seeking to prolong the energizing effects of their morning coffee, incorporating a bit of grapefruit into your routine might be the secret.
The reason lies in a unique compound found in grapefruit, which interacts with various substances. This interaction is so significant that healthcare professionals often advise against consuming grapefruit alongside numerous medications.
This compound’s primary role involves inhibiting an enzyme in the digestive system responsible for breaking down certain substances. As a result, a higher concentration of the drug can enter the bloodstream, potentially leading to dangerously elevated levels, as highlighted by Harvard Medical School.
The fascinating aspect of this grapefruit compound is its potential influence on caffeine metabolism. Some experts theorize that it may slow down the breakdown of caffeine, thereby extending its stimulating effects.
It’s this same chemical in grapefruit that some theorize could slow down the metabolizing process of caffeine and make its energizing effects last longer.
Buddy Brew Coffee, a chain of Florida coffee shops, is testing the theory with its “Buddy Brew Screw.”
The menu item features a shot of espresso, a side of grapefruit juice and, to cut the bitterness of both drinks, a small spoonful of salt, Food & Wine reported.
A person would have to consume “a lot” of grapefruit to feel the added high, said Michelle Francl, a professor of chemistry at Bryn Mawr College.
Even then, results are not guaranteed.
Several studies on the relationship between grapefruit juice and caffeine have been inconclusive, according to Food & Wine.
The ability to clear caffeine also varies from person to person, Francl noted.
Eating vegetables like broccoli, cabbage and Brussels sprouts may speed up the process, she said.
“Compounds in grapefruit juice can theoretically slow caffeine metabolism, but the actual effect is far from a guaranteed energy boost,” Lauren Manaker, a South Carolina-based dietitian nutritionist, told Fox News Digital.
The evidence suggests any extension of your coffee buzz is “likely to be very minor” and will be different for each person, she said.
“From a practical standpoint, this biochemical interaction is simply not strong enough to make a noticeable difference in your daily energy levels,” Manaker said.
“Most importantly,” she added, “grapefruit alters the absorption of many common medications, making this a potentially dangerous trend if you take certain prescription drugs, like statins.”
While grapefruit juice might not do much to prolong the caffeine buzz, it does offer health benefits of its own.
It’s rich in vitamin C and antioxidants, among other things. However, people taking prescription medications should be cautious when consuming grapefruit and grapefruit juice.
Moderate amounts of caffeine can boost mood and energy levels and enhance cognitive and physical performance, according to the Cleveland Clinic.
It is also effective in headache relief and may lower the risk of disease, including Alzheimer’s and Parkinson’s.
Side effects of caffeine could include increased heart rate, anxiety and digestive problems, among others.
