Coffee Lovers, Rejoice: That Morning Cup Might Just Be Adding Years to Your Life
A Norwegian study from 2015 revealed that people who drank two or more cups a day had a 40% lower risk of death from liver cirrhosis
Love starting your day with a steaming cup of coffee but worried it might be harming your health? You're not alone. But new research, including a major study from Tufts University, is flipping the narrative. It suggests that drinking coffee in moderation could actually help you live longer. Liver expert Dr. S.K. Sarin helps us separate fact from froth.
Can coffee really reduce mortality risk?
According to Dr. Sarin, yes — and the evidence is strong. 'Coffee's effects on health have been studied intensively for over two decades," he says. The Tufts University study, presented at the annual American Society for Nutrition meeting, tracked over 46,000 people for 10 years. Results showed that those who consumed 1–2 cups of coffee daily had a 14% lower risk of dying from cancer and cardiovascular diseases.
Backing this up, a massive UK Biobank study with over 1.89 lakh participants found that drinking more than two cups of unsweetened coffee each day was associated with an 11–16% reduction in new cancers and cancer-related deaths.
How does coffee benefit liver health?
'Coffee has been shown to lower liver fat and reduce inflammation," says Dr. Sarin. A Norwegian study from 2015 revealed that people who drank two or more cups a day had a 40% lower risk of death from liver cirrhosis. According to him, coffee can almost act like a therapeutic agent for metabolic liver conditions — but with a crucial caveat. 'It's not a remedy for unhealthy habits like smoking, excessive alcohol, or junk food," he warns.
What about overall wellness?
Beyond liver health, coffee has a wide-ranging impact on metabolic syndrome — the cluster of conditions including high blood pressure, obesity, high cholesterol, and diabetes. 'Coffee positively alters gut microbiota, has anti-inflammatory properties, and even contains compounds that combat cancer," Dr. Sarin explains.
It's also a natural energy booster. Moderate coffee consumption is linked to a lower risk of stroke and dementia. A meta-analysis involving 3.5 lakh people showed that each additional cup of coffee reduces the risk of depression by 8%.
Isn't caffeine harmful in excess?
That's true — and moderation is key. Overconsumption of caffeine can lead to jitteriness, anxiety, insomnia, and elevated heart rate. But in controlled doses, caffeine delivers impressive health perks. 'It has antioxidant, anti-fibrotic, and anti-lipid effects," says Dr. Sarin.
Caffeine works by blocking adenosine, a neurotransmitter that makes you sleepy, and instead releases mood-lifting chemicals like dopamine and serotonin. Coffee is packed with nearly 1,000 bioactive compounds, including chlorogenic acids, kahweol, and cafestol — all of which have various protective effects on the body.
What about decaf?
While decaf has less caffeine, it still retains beneficial compounds like chlorogenic acid, which lowers glucose absorption and enhances insulin sensitivity. 'Coffee also increases adiponectin levels — a hormone that boosts fat metabolism," explains Dr. Sarin. Kahweol and cafestol, although found in lesser amounts in decaf, are potent antioxidants that protect tissues from damage.
Does milk and sugar cancel out the benefits?
'In moderation, a little milk can actually reduce acidity," says Dr. Sarin. But it's a trade-off. Milk reduces the absorption of chlorogenic acid — a major anti-inflammatory component of coffee — and may not suit those with lactose intolerance. Add sugar, and you're also adding unnecessary calories.
'For maximum health benefits, go for drip coffee or plain black coffee," he advises. 'Remember, coffee isn't a miracle drug — it's a beverage. Like any powerful substance, it should be consumed mindfully, at the right time and in the right amount."

Black coffee can lower the risk of death, but there's a catch
Coffee lovers, rejoice! A recent study reveals that your daily coffee might be more beneficial than you think, potentially lowering the risk of all-cause mortality. Researchers at Tufts University discovered that black coffee, or coffee with minimal additives, is linked to a reduced risk of death. Coffee lovers, we have good news for you. Your daily indulgence might actually be doing more than just waking you up - it might be saving you, quite literally. Drinking coffee can lower the risk of all-cause mortality; however, a recent study suggests that making it a certain way could kill its benefits. A new study by researchers from the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University found that drinking black coffee or coffee reduced the risk of death from all causes. However, those benefits may be lost when the beverage is consumed with certain additives. The study is published in The Journal of Nutrition . Coffee, but no additives Coffee may bring some benefits; however, you may want to hold the cream and sugar. The researchers found that the association between coffee consumption and mortality risk changes with the amount of sweeteners and saturated fat added to the beverage. They found that drinking 1-2 cups of caffeinated coffee per day was linked to a lower risk of death from all causes, including cardiovascular disease. Black coffee with low levels of added sugar and saturated fat is linked to a 14% lower risk of all-cause mortality compared to no coffee consumption. The researchers noticed that these benefits were, however, slashed when the coffee was added with high amounts of added sugar and saturated fat. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Glicemia acima de 100? Insira essa fruta na sua dieta Saúde Nacional Undo ' Coffee is among the most-consumed beverages in the world, and with nearly half of American adults reporting drinking at least one cup per day, it's important for us to know what it might mean for health. The health benefits of coffee might be attributable to its bioactive compounds, but our results suggest that the addition of sugar and saturated fat may reduce the mortality benefits,' Fang Fang Zhang, senior author and the Neely Family Professor at the Friedman School, said, in a statement. The study The researchers analyzed data from nine consecutive cycles of the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2018. The study included a nationally representative sample of 46,000 adults aged 20 years and older who completed valid first-day 24-hour dietary recalls. This data was then linked to the National Death Index Mortality Data. Ronnie Coleman Hospitalised: Fans Alarmed Over Sudden Medical Emergency The researchers categorized the coffee consumption by type (caffeinated or decaffeinated), sugar, and saturated fat content. They also included mortality outcomes such as all-cause, cancer, and cardiovascular disease. The amount of low added sugar (from granulated sugar, honey, and syrup) was defined as under 5% of the Daily Value, which is 2.5 grams per 8-ounce cup or approximately half a teaspoon of sugar. The low saturated fat (from milk, cream, and half-and-half) was defined as 5% of the Daily Value, or 1 gram per 8-ounce cup or the equivalent of 5 tablespoons of 2% milk, 1 tablespoon of light cream, or 1 tablespoon of half-and-half. The findings The findings were striking. The researchers found that drinking at least one cup per day was linked with a 16% lower risk of all-cause mortality. When the coffee consumption was increased to 2-3 cups per day, the link rose to 17%. No benefits were found beyond three cups. 'Few studies have examined how coffee additives could impact the link between coffee consumption and mortality risk, and our study is among the first to quantify how much sweetener and saturated fat are being added. Our results align with the Dietary Guidelines for Americans which recommend limiting added sugar and saturated fat' first author Bingjie Zhou, a Ph.D. graduate from the nutrition epidemiology and data science program at the Friedman School added.

Walk your way out of back pain: Study finds 100-minute weekly walks cut pain by 23%
If your back is constantly aching from sitting for too long, there is some good news that does not require painkillers or expensive therapy. According to a new study, walking could be the simplest solution. Just 100 minutes per week could reduce chronic lower back pain by almost a quarter. A Norwegian study discovered that walking 100 minutes per week can reduce the risk of chronic lower back pain by 23%. The low-impact movement improves spinal mobility, strengthens support muscles, and promotes good posture. Best of all, it's simple, drug-free, and easy to incorporate into your daily routine. ALSO READ: Protein overload may raise uric acid, experts warn of hidden risks in high-protein diets People in their 20s, 30s, and 40s who are stiff, uncomfortable, and prone to periodic spasms are drawn to this "no pain pill" method. According to the study, which looked at medical records from 11,000 adult participants, increasing the amount of time and intensity of exercise may help lower the risk of getting chronic low back pain. Because the gains leveled off at that point, the 100-minute limit was chosen, as per a report by The Indian Express. Due to the fact that we sit more often than we move, persons in their 20s, 30s, and 40s are reporting stiffness, pain, and recurrent spasms at alarming spinal circulation, muscle loss, stiffness of the hip flexors, which are used to lift and bend your leg, compressed discs, and eventually discomfort are the results of this over time. Thus, everyday motions start to feel like enormous it softly moves the spine and nourishes and mobilizes the spinal tissues, walking is an essential activity for maintaining the health of the spine. It increases circulation and engages the hip, pelvic, gluteal, and core muscles, all of which are essential for spinal support. Walking lengthens the spine, raises the chest, promotes a healthy rhythm, and strengthens these muscles without overtaxing them. Walking helps people lose weight, especially those with lower back discomfort, because it is low-impact and restores vertical integrity. Walking causes the production of endorphins, which are naturally occurring chemicals that reduce pain.• Plan for 30-minute morning, 30-minute lunch, and 40-minute evening walks.• Use walking during phone calls, stairs, parking, pet walks, or coffee breaks.• Focus on momentum, not supportive shoes, take rest breaks, and choose flat, familiar routes to start with pain management small, even for five minutes. Does walking actually help with back pain?Yes. Walking improves circulation, loosens stiff muscles, and gently strengthens the spine-supporting core and hips, all of which help to relieve low back pain. Do I have to walk 100 minutes at once? Not at all. Break it up into short walks of 10 to 30 minutes each throughout the day. Consistency is more important than duration.
