The researchers found that these results applied to ground, instant, and decaffeinated coffee varieties.

Ground, Instant & Decaffeinated Coffee

Professor Kistler, in a press release from the European Society of Cardiology, said that in this large observational study, ground, instant and decaffeinated coffee were associated with a reduction in the incidence of cardiovascular disease and death from cardiovascular disease or any other cause.

"The results suggest that moderate to moderate consumption of instant ground coffee and decaffeinated coffee is part of a healthy lifestyle," Kestler added.

There is little information about the effect of different coffees on heart health and survival. This study examined the associations between coffees, accidental arrhythmias, cardiovascular disease, and death. Using data from the UK Biobank, which took information from adults aged 40 to 69. Cardiovascular diseases include coronary heart disease, congestive heart failure, and stroke.

Number Of Coffee Cups

The study included 449,563 participants, with an average age of 58 years, 55.3% of whom were women, and had no arrhythmia or other cardiovascular disease at all.

Participants answered a questionnaire asking how many cups of coffee they drink each day, and if they usually drink instant coffee, ground coffee (such as cappuccino or filter coffee) or decaffeinated coffee.

Coffee drinkers were compared with others in terms of arrhythmia, cardiovascular disease, and death, and the median follow-up was 12.5 years.

The study found the following: 
Drinking coffee and the risk of death

The greatest reduction in the risk of death was with drinking 2 to 3 cups a day, compared to not drinking coffee, according to the following ratios:

Decaffeinated coffee: 14% 
Ground coffee: 27% 
Instant coffee: 11%

Coffee & Heart Disease

The greatest reduction in the risk of cardiovascular disease was with drinking two to three cups a day, compared to not drinking coffee, according to the following ratios:

Decaffeinated coffee: 6% 
Ground coffee: 20% 
Instant coffee: 9%

Coffee & Irregular Heartbeat

Ground coffee and instant coffee, but not decaffeinated coffee, were associated with a decrease in arrhythmias, including atrial fibrillation, when compared to non-coffee drinkers.

The lowest risk was observed with 4 to 5 cups per day for ground coffee and 2 to 3 cups per day for instant coffee, with reduced risks of 17% and 12%, respectively.

Coffee Contains More Than 100 Biologically Active Ingredients

Professor Kistler said: "Caffeine is the most well-known component of coffee, but it contains more than 100 biologically active ingredients. It is possible that non-caffeine compounds are responsible for the positive relationships observed between coffee drinking and cardiovascular disease and survival."

“Our findings suggest that drinking modest amounts of coffee of all kinds should be encouraged, but that coffee drinking can generally be enjoyed as a heart-healthy behaviour.”

Coffee Lovers

According to the occasion’s website, on World Coffee Day 2022, members and partners of the International Coffee Organization come together to move the coffee sector from a linear economy to a circular economy, and realize that converting waste in the coffee sector into new products and alternative energy options provides important income and job opportunities and reduces production costs.

According to a report in the Harvard TH Chan School of Public Health website, coffee lovers around the world who drink their favorite morning drink may not think about its health benefits or risks, yet this drink has been the subject of a long history of debate.

In 1991, coffee was listed as a carcinogen by the World Health Organization, and by 2016 it had been cleared; Research found that the drink was not associated with an increased risk of cancer. Conversely, there was a reduced risk of some types of cancer among those who drank coffee regularly.

Additional accumulating research indicates that when consumed in moderation, coffee can be considered a healthy drink. 
coffee contains:

Caffeine 
Vitamin B2 (Riboflavin) 
magnesium 
Phytochemicals: Polyphenols, including chlorogenic acid, quinic acid, and diterpene, including cafestol and cowell. 
One 8-ounce cup of brewed coffee contains about 95 milligrams of caffeine. A moderate amount of coffee is generally defined as 3-5 cups per day, or on average 400 milligrams of caffeine.

Coffee & Health

Coffee is a complex mixture of more than a thousand chemicals. What distinguishes a cup is the type of coffee bean used, how it is roasted, how much is ground, and how it is brewed. Human response to coffee or caffeine can also vary greatly.

Low to moderate doses of caffeine (50-300 milligrams) may increase alertness, energy, and ability to focus, while higher doses may have negative effects such as anxiety, insomnia, and increased heart rate.
