Grapefruit could make your coffee buzz last longer as experts warn of hidden risks
If you’re looking to extend the caffeine buzz from your daily coffee, a taste of grapefruit might do the trick.
Grapefruit contains a chemical that interacts with other substances, which is why doctors caution against pairing it with dozens of medications.
The chemical works by blocking an enzyme in the digestive system that helps break down certain substances, allowing more of the drug to enter the bloodstream. Drug concentrations in the blood can rise too fast and to dangerously high levels, Harvard Medical School reported.
SCIENTISTS USED ELECTRICITY ON COFFEE AND DISCOVERED WHAT MAKES IT TASTE GOOD
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.

Super Bowl champion Joe Theismann says the NFL’s is losing tradition to streaming-era scheduling
Super Bowl champion Joe Theismann said the NFL has left tradition behind.
The NFL has expanded their primetime schedule to holidays and playing games overseas, meaning they are playing more games outside of the traditional Sunday afternoon timeslot. Theismann pointed out the drastic differences in how the games are broadcast.
“They’ve drifted away (from tradition). I mean, when you look at all the different streaming services and all the different networks, it used to be ABC, NBC, and CBS, but that doesn’t exist anymore. There only used to be those TV channels where you could watch things other than sports only existed then,” Theismann told Fox News Digital in a recent interview.

“Now, we’re in a time and a place where the opportunity for the owners to make lots of money from different entities, from YouTube, from Amazon, from Peacock.”
Theismann said fans used to look forward to Sundays, but now there are games seemingly all the time.
“Sunday is something you would look forward to sitting down to because you really didn’t have an option. Now you have options on Monday night, Thursday night, Wednesday night, God only knows, Tuesday night, Saturday evening. If you’re a fan of the NFL, you’re going to find the game,” Theismann said.
The opening game of the 2026 season will be on Wednesday this season, with the second game being played in Melbourne, Australia, on a Thursday. The NFL introduced a Thanksgiving Eve game this year, adding another Wednesday game to the schedule.

There will also be NFL games on Friday this year, as the league has gone forth with its fourth annual Black Friday game. The NFL also has three games scheduled on Christmas Day, which is a Friday.
Once the college football regular season ends in mid-December, there will also be Saturday games.
Theismann did say the NFL now has gotten fans easier access to watch more games, which he considers a good thing.
“It gives you a chance to find the game that you want to watch now. You don’t have to read about it the next day. So, in one regard it’s grown the NFL and the other side of it, yeah, would we all like things to be a little bit like they used to be? Maybe. But I believe in the progressive as a progressive individual, but life is changing. You have to adapt and change with it,” Theismann said.

This will be the 37th American Century Championship, and Joe Theismann has played in 36 of them. He said he used to be a 2-handicap, but is now a nine, as he doesn’t hit the ball as far. He will look to turn back the clock when he plays in the tournament from July 10-12 at Edgewood Golf Course in Lake Tahoe.
He said the American Century Championship is the lone thing that you really want to participate in.
“The American Century Championship has evolved to one of those things that, if you love golf at all, and you happen to be in that quote-unquote celebrity world, it’s the thing you really want to participate in. You get to measure your game. You get to pull back the curtain on so many wonderful people, and you get to see those that you watch on TV because I’m a fan of everything. But now you get a chance to see them up close and personal, and you get a chance to meet them and get to know them, and it’s exciting,” Theismann said.
The 76-year-old said he gets to visit people on the range. He mentioned Jerry Rice, Tony Romo and Miles Teller as people he has had conversations with, calling himself a “fanboy” of Teller’s.
Theismann said “Top Gun: Maverick” is his favorite movie of all time.
The tournament has raised more than $8 million for regional and national charities. American Century Investments donates 40% of its profits to the Stowers Institute for Medical Research and activates fundraising at the tournament to drive direct donations to Stowers each year. Theismann credited CEO Jonathan Thomas for the tournament’s charitable work.
