When Dr. David Kao tells patients they have atrial fibrillation, their first question is usually "Do I have to give up coffee?" His answer often surprises them: No. "Because it's a stimulant, they feel their heart is going to race and be worse off, especially when you have an arrhythmia like atrial fibrillation," said Dr. José Joglar. "But it's not in the science." Joglar was the lead author of new guidelines from the American College of Cardiology and the American Heart Association on diagnosing and treating atrial fibrillation, or AFib, published recently in Circulation. Among the detailed discussions of lifestyle...

Caffeine restriction can help improve and reduce the severity of primary monosymptomatic nocturnal enuresis (PMNE), according to a study. Sadra Rezakhaniha and colleagues investigated the effect of caffeine restriction on the improvement and severity of PMNE in a randomized clinical trial involving 534 children aged 6 to 15 years. Caffeine consumption was <30 mg/day in the intervention group and 80 to 110 mg/day in the control group. Before caffeine restriction, the mean number of bed-wettings was 3.5 and 3.4 times/week in the intervention and control groups, respectively. The researchers found that at one month after the intervention, the mean number...

Stop with the salt: adding a dash of water to coffee beans before grinding them could be the secret to a better-tasting cup of caffeinated goodness, new research suggests. The trick boils down to reducing the amount of static electricity generated by grinding whole coffee beans, which otherwise causes them to clump together and clog up the grinder, creating a whole lot of mess and waste. Coffee buffs have long been spritzing their beans to moisten them before grinding. Now scientists have confirmed what makes sparks fly in ground coffee beans – and shown how budding baristas can reduce that...

A new study found that (TG), a natural compound in coffee and some vegetables, significantly enhances spatial learning and memory in aged mice. The research indicates that TG modifies key molecular pathways and reduces neuroinflammation, highlighting its potential in addressing age-related cognitive decline. Recent research has increasingly focused on finding natural compounds that can counteract age-related cognitive decline and promote healthy aging. Trigonelline (TG), a plant alkaloid found in coffee, fenugreek seeds, and radish, has been suggested as a candidate for enhancing cognitive abilities. In a new study, researchers led by the University of Tsukuba investigated the effects of TG...

Investigators found odd, little pills buried in the pockets of Hamas terrorists who attacked Israel on Oct. 7. They were later identified as the drug Captagon, a powerful, synthetic stimulant. Captagon gained international notoriety in 2015 when it was discovered to be used by ISIS fighters to suppress fear and fatigue prior to carrying out terrorist operations. Now, because it’s cheap, as well as easy to make and smuggle, Captagon and its counterfeits are likely to remain a favorite tool of extremist militant groups to enhance their soldiers’ violent tendencies. Some reports have even labeled Captagon as “the jihadists’ drug,”...

New research by Singapore’s National Neuroscience Institute (NNI) also revealed that carrying one of two Asian gene variants increases your risk of Parkinson's disease. And up to 10 per cent of the Singapore population carry one of these gene variants.offee and tea drinkers, rejoice – especially those with a genetic predisposition to developing Parkinson’s disease (PD). New research by Singapore’s National Neuroscience Institute (NNI) has found that two cups of kopi (traditional local coffee made from robusta coffee beans) a day can reduce the risk of PD by four to eight times in people with Asian gene variants linked to...

A study finds that chronic caffeine consumption has surprising effects on sleep patterns and brain blood flow in mice, increasing brain blood flow during sleep. The study was conducted using a minimally invasive microchip and video recording system. The study found that mice consistently have a "siesta" during the latter part of their awake phase. Daily caffeine abolished this siesta and consolidated wakefulness during the awake phase It also shifted the onset of sleep (particularly REM sleep) by up to 2 hours relative to the light dark cycle. Interestingly, the mice that consumed caffeine when awake slept more solidly, and...

Whether enjoyed on its own or mixed into a latte, Americano or even a martini, espresso provides an ultra-concentrated jolt of caffeine to coffee lovers. But it might do more than just wake you up. Research shows that, in preliminary in vitro laboratory tests, espresso compounds can inhibit tau protein aggregation—a process that is believed to be involved in the onset of Alzheimer's disease. Recent research has suggested that coffee could also have beneficial effects against certain neurodegenerative diseases, including Alzheimer's disease. Although the exact mechanisms that cause these conditions are still unclear, it's thought that a protein called tau...

A recent study compared the gut microbiota and gut-derived metabolites between healthy controls and individuals with fatty liver. The results revealed that certain microbial metabolites are associated with liver fat content. The fact that the gut microbiota associates with many diseases, has raised the hope that they could be used for diagnostic purposes. One of the progressing research fields is the analysis of gut-derived metabolites that are manufactured by the microbes from the food. Fatty liver disease is the most common chronic liver disease world-wide, especially in individuals with obesity, and it predisposes to cardiovascular diseases. The recent study compared...

Researchers have found that the association between heavy coffee consumption and kidney dysfunction hinges on a common genetic variation. The researchers showed that markers of kidney dysfunction were nearly three times higher in heavy coffee drinkers with a variant of the CYP1A2 gene that makes them slow metabolizers of caffeine than for other heavy coffee drinkers who had a different version of the gene that enables faster caffeine metabolism. "We think fast metabolizers can eliminate caffeine from their systems more efficiently and avoid harmful build-ups," said Ahmed El-Sohemy. "These individual differences in caffeine metabolism help explain why previous studies on...

NATIONAL ESPRESSO DAY Get the pure coffee essence on National Espresso Day! Whether you sip one cup or keep buzzing all day long, November 23rd is the day. #NationalEspressoDay The word espresso (/ɛˈsprɛsoʊ/; Italian pronunciation: [eˈsprɛsso]) in Italian means ‘quick in time.’ Before the advent of the espresso machine, espresso was simply a coffee expressly made for the person ordering it. It was also made with recently roasted and freshly ground beans. The cup was brewed shortly before serving. In the late 1800s, this practice was commonplace in cafés and restaurants. While today’s espresso maintains the freshness quality, it has...

On Wednesday, participating Dunkin’ locations across the nation will begin offering hot or iced versions of its new Extra Charged Coffee, which is made with green coffee extract to give customers "an extra boost" of caffeine. The company added that it aimed to achieve its caffeine-forward Extra Charged Coffee with green coffee extract, rather than a shot of espresso, to avoid changing the "flavor profile" of the Original Blend coffee that its customers already "know and love." For Dunkin’s more adventurous customers, the brand is also introducing two completely new coffee blends: Dunkin’ Explorer Batch, a medium roast featuring "dark...

Green tea is one of the healthiest beverages on earth: It’s full of flavonoids that can help reduce inflammation, aids in lowering bad cholesterol and can lessen your chances of heart attack or stroke, Harvard Medical School tells us—all important factors to counteract the effects of the day-old cheese stick and half a sleeve of crackers you sometimes refer to as “lunch.” But does this mean you can drink green tea before bed and reap all its healthy benefits? The short answer: No. Well, not if you want to get a good night’s sleep. Wait, why can’t I drink green...

Who is the woman at the center of the viral coffee chugging moment during Tuesday’s impeachment hearing? The woman dramatically drank her beverage as Lt. Col. Alexander Vindman testified. She tilted her head back to take a big gulp before seeming to remember she was on camera. Her name is Emma Dumain . . .

The study, co-authored by Maglio and published in the journal Consciousness and Cognition, looks at an effect called priming, through which exposure to even subtle cues can influence our thoughts and behavior. “People often encounter coffee-related cues, or think about coffee, without actually ingesting it,” says Maglio, an expert on consumer behavior. Arousal in psychology refers to how specific areas of the brain get activated into a state of being alert, awake and attentive. It can be triggered by a number of things, including our emotions, neurotransmitters in the brain, or the caffeinated beverages we consume. In this case, the...

A team of scientists at the university studied wastewater that's entering into the river from nearby sewers during storms and found traces of the drug within 24 hours of the overflow, the Independent reports. Compared to other major cities, the level of cocaine entering London's water system — likely through users' urine — is much higher. "Increases in caffeine, cocaine and benzoylecgonine [a metabolite] were observed 24 hours after sewer overflow events,' King's College London researchers said in a paper that detailed their findings, according to the Evening Standard. London's water treatment plants are tasked with purifying the water but major storms reportedly "overwhelm"...

Companies can no longer sell bulk packages of liquid or powdered caffeine directly to consumers, the Food and Drug Administration announced Friday. The policy will take immediate effect “given the significant public health concern,” according to the agency’s statement released Friday. “Highly concentrated and pure caffeine, often sold in bulk packages, have been linked to at least two deaths in otherwise healthy individuals,” the agency stated. ... Between 10 and 14 grams of caffeine is considered life-threatening, according to the FDA’s guidelines, though people can have an irregular or rapid heart rate and seizures after taking just a gram. The...
