Coffee Lovers; How Much Can Cause An Effect On The Heart?

Many individuals think coffee as a magical preparation that initiates the day, a very vital necessity in the afternoon and also a welcoming drink as digestion after dinner time. Nevertheless, when do you know you’ve had enough coffee? A new research brings the answer to light.

“What on earth could be more luxurious than a sofa, a book, and a cup of coffee?”writes the Victorian writer Anthony Trollope in his 1855 novel The Warden.

Any reason which brings people to coffee , whether its the taste and smell or used as an antidepressant, it is to be mentioned without fail that it is one of the most demanded beverages.

in USA, coffee drinking is increasing rapidly. The statistics in the report show that, in 2018/2019, people in USA have devoured almost 26.5 million 60 kg bags of coffee. The same reports show that it has been consumed more this year than the previous year.

Other results demonstrate that in 2018, close to half of young generation (18-24 yrs) where consuming coffee and roughly three-quarters of older individuals were also seen drinking coffee. Many latest studies have advised that drinking coffee can be beneficial in numerous ways for example to increase focus and productivity. Also, researchers have claimed that coffee can help in retaining brain health, add number to a persons longevity and even slow the process of prostate cancer.

Though, with any food or drink even if it is the healthiest and packed with nutrients, there is a fine line to how much one can consume, even in the case of coffee. Too much intake of coffee creates bad affects in the short run, symptoms include migranes, dizziness and nausea and continuously drinking too much could have a higher risk of an individual being prone to cardiovascular disease.

So, what amount is considered “a lot” for the heart? This is the vital question which scientists in University of South Australia in Adelaide decided to reply to in their new study, the results which are shown in the American Journal of Clinal Nutrition.

Observers identify the ‘warning point’

The observers combined with previous studies demonstrated that individuals with a certain variant of the gene CYP1A2, that has an important role in caffeine metabolism, metabolize this material less effectively. This causes a higher risk of being prone to high blood pressure (hypertension) and cardiovascular disease. In the new observation, the observers were keen to find out the amount of coffee that would raise the risk of cardiovascular in people with or without this genetic variant. They then found out by examining the data of 347,077 people of age 37-73 from which 8368 had cardiovascular disease. The scientists checked the data through UK Biobank.

“An estimated 3 billion cups of coffee are enjoyed every day around the world,” says the study co-author Prof. Elina Hyppönen. For this reason, she further adds, “knowing the limits of what’s good for you and what’s not is imperative.” “As with many things,” she warns, “it’s all about moderation; overindulge and your health will pay for it.”

In their observation, the scientists saw how much coffee was consumed by the members each day, if they did or didn’t have the genetic variant which concluded in slow caffeine metabolism, and the chances of developing cardiovascular disease. It was known that despite the information that individuals without the specific CYP1A2 genetic varient were capable to take in caffeine four times quicker than those with it, which did not impact their cardiovascular risk. Though, the quantity of coffee they took in every day did.

As a fact, everyone who usually had a dose of six or more cups of coffee every single day – the scientists explained one cup having around 75 miligrams of caffeine – and an increase in cardiovascular disease risk.

“Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable, or perhaps even feel nausea — that’s because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being,” says Prof. Hyppönen. “We also know that risk of cardiovascular disease increases with high blood pressure, a known consequence of excess caffeine consumption,” she adds.

“In order to maintain a healthy heart and a healthy blood pressure, people must limit their coffees to fewer than six cups a day — based on our data six was the tipping point where caffeine started to negatively affect cardiovascular risk.” as advised by Prof. Elina Hyppönen
