Benefits Of Coffee: Drinking Coffee Might Reduce Risk Of Stroke, Heart Disease

Subjects who consumed an eight-ounce cup every day lowered their risk of each by 8 percent, 7 percent, and 5 percent, respectively.

Fortunately, it seems that my coffee-drinking habits may mean that I'm less exposed to certain health risks, according to new research by the University of Colorado School of Medicine in Aurora.

Researchers re-analysed data from the Framingham Heart Study, a long-running USA investigation of heart disease risk factors involving thousands of participants.

A press release stressed that this type of study demonstrates an observed association, but does not prove cause and effect.

The researchers then confirmed their findings with more traditional analyses of two additional large study groups: the Cardiovascular Heart Study and the Atherosclerosis Risk in Communities Study.

But researchers are still behind this learning technology.

The findings were to be presented Monday at the heart association's annual meeting in Anaheim, Calif.

Adding just one extra cup of coffee a week may be enough to reduce the risk, and the research published by the American Heart Association found no limit to how much you can consume.

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". In this case, red meat consumption was identified as a potential risk factor, although here, the correlation was less striking. Instead, they suggest replacing it with chicken, fish, and beans.

The researchers also built a predictive model using known risk factors from the Framingham Risk Score such as blood pressure, age and other patient characteristics associated with cardiovascular disease. "We don't yet know if it is the coffee intake itself or another behaviour that might go along with it", she says.

Senior author Professor David Kao said: 'Machine learning may be a useful addition to the way we look at data and help us find new ways to lower the risk of heart failure and strokes'.

The scientists will go on to explore risk factors for those two events and aim to better understand how our diets influence our cardiovascular health. "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.

The new research also supports the idea that machine learning may help researchers identify other unknown risk factors-or protective factors-for disease.
