Coffee lowers risk of heart failure, stroke drastically

Coffee lowers risk of heart failure, stroke drastically”

DRINKING just one cup of coffee a week can reduce your risk of heart failure by seven per cent, new research suggests.

Having the breakfast brew could lower the risk of a stroke by eight per cent and heart failure by seven per cent, with increased reductions dependent on how much you have.

The report one extra cup can make a huge and positive difference.

Still, the researchers noted that their study only found an association, and can not prove a "cause and effect" relationship between coffee consumption and a lower risk of stroke and heart failure.

Adding, "The work showed that each additional cup per day had an associated decrease of each outcome". Other dietary patterns, such as convenience, sweets, Southern, or salads/alcohol style, were not related to the reduced risk of heart failure.

"More research is needed before we can confidently say how coffee consumption may impact our heart health".

Researchers used a machine to analyse data from the long-running Framlingham Heart study. Although caffeine seems bad for the heart, consuming it regularly can prevent people from suffering both strokes and heart failure.

Lead researcher Dr Kyla Lara, from Mount Sinai Hospital in NY, said: "Eating a diet mostly of dark green leafy plants, fruits, beans, whole grains and fish, while limiting processed meats, saturated fats, trans fats, refined carbohydrates and foods high in added sugars is a heart-healthy lifestyle and may specifically help prevent heart failure if you don't already have it".

Stevens and team also found a correlation between how much red meat we include in our diets and the risk of stroke and heart failure.

The research was presented at the American Heart Association's Scientific Sessions 2017, in California. In this case, red meat consumption was identified as a potential risk factor, although here, the correlation was less striking.

"We were not able to validate the association with red meat, due to the definition of red meat not being uniform across these studies", Stevens said. They also are considering whether the coffee drinking might not be the cause of the reduced risk at all - for example, people who drink more coffee might be more fit or have other heart-healthy habits, Stevens said. Nearly all of the coffee drinkers in the study (97%) consumed between one and six cups of coffee a day, says Stevens, so the researchers can't know for sure if the benefits continue at even higher consumption levels. Moreover, they also used machine learning to study all their findings, and what resulted was a correlation between higher coffee consumption and lower chances of experiencing cardiac events.

In a study conducted by Dr Kyla Lara, experts examined five diets which ranged from red meats, to plant based food, candies and alcohol over four years. They hope that machine learning methods will be effective in uncovering hitherto unknown culprits.

In a more surprising finding, the research also suggested that red meat might be linked to lower risk of heart failure and stroke, said Stevens, who is also a doctoral student at the University of Colorado School of Medicine in Aurora. "The risk assessment tools we now use for predicting whether someone might develop heart disease, particularly heart failure or stroke, are very good but they are not 100 percent accurate", said Laura M. Stevens, first author of the study and a doctoral student at the University of Colorado School of Medicine.
