Studies have shown that drinking 2-3 cups of coffee daily will reduce cardiovascular disease (CVD) as well as the mortality rate in humans, in contrast to avoiding coffee altogether.
The coffee should be either ground, instant, or decaffeinated as they are associated with the curtailing of arrhythmia and atrial fibrillation. According to a study, it also prevents coronary heart disease, congestive heart failure, and ischaemic stroke.
A person should have a mild to moderate consumption of coffee, as it is considered as a part of healthy lifestyle.
The Study was conducted by the Baker Heart and Diabetes Research Institute, Australia, among adults between the age of 40-69 years of age. This is to learn more about the link among different types of coffee and how they affects the heart.
“Our findings indicate that drinking modest amounts of coffee of all types should not be discouraged but can be enjoyed as a heart healthy behaviour,” said professor Kistler.
The result was surprising as it showed that not just one or two but all kinds of coffee have the same positive impact on human body as it truly helps in the decrease the risk of death from any causes.
Outstanding results can be achieved if one were to have 2 or 3 cups of instant or 4-5 of ground cups per day. For decaf, ground and instant coffee the reduction percentage is 6, 20 per cent, and 9 per cent respectively.
“While caffeine is the most well-known constituent in coffee, the beverage contains more than hundred biologically active components. It is likely that the non-caffeinated compounds were responsible for the positive relationships observed between coffee drinking, cardiovascular disease and survival,” Kistler added.
What the study revealed about lower heart disease?
At the same time, coffee drinkers were compared to that of non-drinkers on the basis of their age, sex, ethnicity, high BP, obesity, smoking status as well as tea and alcohol consumption.
The results showed that the median follow up was by 12.5 years. Out of the 450,000 people participated, 27,809 (6.2) participants died in the follow up. The questionnaire given to them included questions like their usual intake of coffee every day and whether they drank instant, ground (like cappuccino or filter coffee), or decaf.
They were then divided into 6 daily intake categories consisting of those who never drinks coffee to those who have more than 5 cups a day. The survey further shows that 44.1% of the participants uses instant coffee type, while 18.4% prefers ground and 15.2 drinks decaf.
The rest of the 22.4% are non-drinkers who served as the comparator group. The lower number of coffees gives lower risks of getting any sort of heart disease. Ground and instant coffee reduces arrhythmia except for decaf coffee.
Studies also shows that certain acids present in coffee may also fight against the virus causing Hepatitis-B. Another study conducted in 2018, over a period of ten years has found that coffee drinkers have a 10-15% per cent chance to live longer than those of non-drinkers.
There is an ongoing study on how coffee will even influence the survival for prostate cancer.
“In a broad group (of patients with prostate cancer), coffee didn’t seem to be harmful … maybe survival was a little better in terms of prostate cancer-specific death (for higher coffee intake), but none of it was statistically significant, meaning that we’d hang our hat on it,” said Dr. Justin R. Gregg, an assistant professor in the Department of Urology at The University of Texas MD Anderson Cancer Center in Houston.
“Caffeine is the most well-known constituent in coffee, but the beverage contains more than 100 biologically active components. It is likely that the non-caffeinated compounds were responsible for the positive relationships observed between coffee drinking, cardiovascular disease and survival”, said Kistler.
