2 to 3 cups of coffee per day is linked to improved heart health and longevity

-

Over the years coffee has been criticized and associated with health problems. According to Harvard’s School of Public HealthEarly studies found that coffee intake was associated with serious conditions, including asthma and heart disease. These studies revealed that many of those who participated in the study also smoked cigarettes. Therefore, there was no unfair connection between coffee consumption and good health.

Recent research has shown strong evidence linking coffee consumption with overall better health. We’ve already covered its potential to help reduce the risk of dementia and stroke. Now we’re taking a look at another study that suggests coffee’s positive impact on heart health and life longevity.

A study Publication Date: September 27, 2022, in the European Journal of Preventive CardiologyWe examined the impact of habitual coffee consumption on mortality, arrhythmias, and cardiovascular disease.

Over a period of 10 years, 449,563 participants (median age 58, 55.3% women) were followed by the researchers. For previous studies, false correlations were excluded by taking into account the participants’ BMI, smoking habits, alcohol consumption, and medical history.

The participants were asked to fill out a questionnaire that detailed how much coffee and whether they used instant, ground or decaffeinated coffee each day. The participants were then divided into six categories based on their daily coffee intake: none, less that one, one to three, four- to five, five to seven, and more than five.

Researchers found that coffee drinkers can rejoice in the findings. Here’s the basic breakdown:

  • The risk of arrhythmia fell significantly for those who consumed one to five cups of instant or ground coffee per day. The lowest risks were found for those who consumed four to five cups of instant coffee and two to three cups of ground coffee each day. Decaffeinated coffee drinkers did not experience a lower risk of arrhythmia.
  • There was a lower risk of developing cardiovascular disease when you drink two to three cups of instant or ground coffee, compared to those who don’t.
  • Consuming 2 to 3 cups of decaffeinated, instant or ground coffee reduced all causes of mortality.

All types of coffee were associated with better health, except arrhythmia and decaf. This is good news for people with caffeine sensitivities. For most correlations, two to three cups per day was the best.

However, the study authors acknowledge that there were limitations to their research. For example, coffee consumption was reported by participants and relied on the assumption that coffee intake would be consistent. It is possible that some participants consumed multiple types of coffee throughout the course the study. The majority of the population was white so these findings might not apply to other ethnicities.

Although more research is needed to correct these issues, the initial findings seem promising for coffee lovers of all kinds.
