Research Finds Drinking 2 to 3 Cups of Coffee Daily is Linked to Longevity

New research suggests a link between drinking two to three cups of coffee daily to longevity on top of giving you a simple boost of energy.

Furthermore, the new study, published in the European Journal of Preventive Cardiology found that daily coffee intake is also linked to a lower risk of cardiovascular disease. The health benefits were observed regardless of whether or not the coffee was caffeinated or not, or whether it was ground or instant.

Health Benefits of Drinking Coffee

The study's results were based on an analysis of roughly 450,000 people's habits. The author of the study, Peter Kistler, said that ground, instant, and decaffeinated coffee were associated with reduced incidence of cardiovascular disease and death from cardiovascular disease or any cause.

Kistler added that the results of the study also suggest that mild to moderate intake of ground, instant, and decaffeinated coffee should be considered as part of a healthy lifestyle. Specifically, the researchers looked at the link between mild coffee consumption and cardiovascular issues, which include coronary heart disease, congestive heart failure, and ischaemic stroke, as per CBS News.

Participants in the study were free of these ailments at baseline and were asked by researchers how much and what kind of coffee they drank every day if any. The team then followed the conditions of the participants for a median time of 12.5 years.

During the observation, cardiovascular disease was diagnosed in more than 43,000 participants, which is 9.6% of the total number of people involved in the study. The researchers found that those who drank two to three cups of coffee per day had the lowest risk of developing the disease.

They also saw that people who drank ground, instant coffee, and decaffeinated coffee showed reduced likelihoods of 20%, 9%, and 6%, respectively. According to Neuro Science News, a total of 27.809 participants, roughly 6.2%, died during follow-up. Cardiovascular disease was found in 43,173 participants, or roughly 9.6%, during follow-up.

Reduced Likelihood of Cardiovascular Disease

Kistler noted that caffeine is the most well-known constituent in coffee, but the beverage contains more than 100 biologically active components. He added that it was likely that the non-caffeinated compounds were responsible for the beneficial aspects and positive relationships observed between consumption of coffee, cardiovascular disease, and survival.

The researchers grouped the participants into six daily intake categories, ranging from none to more than five cups of coffee per day. The team used medical records and death records to track the participants' incidence of arrhythmias, cardiovascular disease, and death.

This was done after they adjusted for age, sex, ethnicity, obesity, high blood pressure, diabetes, obstructive sleep apnea, smoking status, and tea and alcohol consumption. Ground and instant coffee, but not decaffeinated, were also associated with a reduction in arrhythmias, including atrial fibrillation, UPI reported.

The recent study builds on previous research that coffee has several apparent health benefits, especially when taken in multiple cups per day. In 2018, a study found that over the course of a decade, coffee drinkers were roughly 10% to 15% less likely to die than non-coffee drinkers.
