One Way of Drinking Coffee Could Help You Live Longer, Study Finds
Take your coffee black, and it could help you live longer: That's according to a new study that found coffee drinkers tend to live longer, but only those who put little or no sugar and saturated fat in their beverages. This notion coffee reduces the chance of an early death has been around for a while. Here the study team, led by researchers from Tufts University, wanted to look specifically at whether what you add to your coffee makes a difference. "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," says epidemiologist Bingjie Zhou from Tufts University. "Our results align with the Dietary Guidelines for Americans which recommend limiting added sugar and saturated fat." Related: The team crunched the stats on 46,332 US adults aged 20 or over, recorded in government health surveys, over the course of 9-11 years on average. In that time, 7,074 people died – deaths which were then cross-referenced against coffee consumption. Coffee drinkers showed a notably lower risk of all-cause mortality, the researchers found, but when more than a little sugar and saturated fat (as found in full-cream milk or cream) was added to the mix, that statistical significance went away. Overall, drinking black coffee or coffee with very low sugar and fat content was linked to a 14 percent reduction in the chance of an earlier death, compared to drinking no coffee at all. Between two or three cups a day seems to be the sweet spot. While the researchers did factor in variables that might have affected mortality rates – including exercise levels, alcohol intake, age, sex, and education level – the study isn't thorough enough to prove direct cause and effect. There may still be unknown variables influencing both coffee drinking and all-cause mortality. However, the data here does show a strong association, and does fit in with previous research into the health benefits of coffee. This study suggests that caffeine drives those benefits, as decaffeinated coffee drinkers saw no difference in mortality rates, and that sugar, milk, and cream might dilute the positive effects. "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," says Fang Fang Zhang from Tufts University. There's plenty more still to look into here, not least how the many different components of coffee might be protecting against an early death. There are likely to be numerous factors involved – including when you actually drink the stuff, as shown by a study published at the start of the year. This new research is particularly helpful in that it isolates the coffee itself from anything else we may throw into it, which isn't the case for all studies like this – with each study often focusing on an angle of its own. "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," says Zhang.

One-two cups of black coffee daily could lower risk of death by 14%: Study
New Delhi: Drinking a cup or two of black coffee daily could lower risk of death by 14 per cent, but adding milk or sugar could diminish the benefits, according to a new study. The same link was not observed for coffee with high amounts of added sugar and saturated fat, researchers said. "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, from Tufts University in the US, and senior author of the study published in The Journal of Nutrition, said. Data nine consecutive cycles of the US' National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018, linked to national death data, was analysed. Responses of more than 46,000 adults aged 20 years and above who completed first-day 24-hour dietary questionnaires were looked at. Coffee consumption was categorised by type -- caffeinated or decaffeinated -- sugar, and saturated fat content, and outcomes of death studied included those from any cause, cancer, and cardiovascular disease. "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," first author Bingjie Zhou, a PhD graduate from Tufts University, said. The authors wrote, "Consuming black coffee and coffee with low levels of added sugar and saturated fat was associated with a 14 per cent lower risk of all-cause mortality, compared with no coffee consumption." Consuming two to three cups a day could lower the risk of death due to any cause by 17 per cent, whereas taking more than three cups daily was not associated with additional reductions, the researchers said. Further, the link between coffee and a lower risk of death by cardiovascular disease weakened when more than three cups of coffee were taken a day, they added.>

How many cups of coffee do you drink a day? Science says this exact amount could lower death risk by 14%
Having one or two cups of black coffee each day could reduce the risk of dying early by 14%, according to a new study quoted by PTI. But adding sugar or milk might reduce these health benefits, researchers have warned. The study, published in The Journal of Nutrition, was led by Fang Fang Zhang from Tufts University in the US. She explained, 'The health benefits of coffee might be due to its bioactive compounds, but our results suggest that adding sugar and saturated fat may take away these benefits.' What the study found The research team studied data from over 46,000 adults aged 20 and above. The data came from nine cycles of the US National Health and Nutrition Examination Survey (NHANES), collected between 1999 and 2018. This information was then linked to national death records. Participants reported what they ate and drank in a 24-hour period. Based on that, their coffee habits were studied, whether they drank it with or without caffeine, how much sugar and saturated fat they added, and how many cups they consumed. Black coffee vs coffee with sugar and fat Bingjie Zhou, first author of the study and a PhD graduate from Tufts, said, 'Few studies have looked at how coffee additives affect the link between coffee and mortality. Our study is one of the first to measure how much sugar and saturated fat people are adding.' Live Events The researchers found that people who drank black coffee or coffee with very little sugar and fat had a 14% lower risk of dying from any cause compared to those who didn't drink coffee at all. Having two to three cups of coffee a day was linked to a 17% lower risk of death. However, drinking more than three cups a day did not show extra benefits. In fact, the link between coffee and reduced death from heart disease became weaker beyond that point. Key takeaway While coffee may offer health benefits, the study suggests that these may only apply when it's drunk plain or with minimal additions. Too much sugar or fat could cancel out the good effects. Inputs from PTI
