Coffee is among the most popular beverages in the world. As a result, considerable research has been conducted on the relationship between coffee and long-term human health. However, a new wave of evidence suggests that the science behind how people consume their coffee has a profound impact on the benefits they may derive from it. It has recently been observed that moderate intake of coffee, especially when taken earlier in the day with fewer additives, can lead to a number of benefits concerning heart problems as well as mortality. These are just a few reasons why scientists are so keen on examining the effects associated with coffee.
Ways coffee may boost heart health and longevity
Morning coffee is linked to better heart health
A 19-year observational study involving 40,725 adults conducted by Tulane University observed the coffee drinking habits of the participants. It found that people consuming coffee in the morning had a 16 per cent reduced risk of death from any cause and 31 per cent from cardiovascular disease.On the contrary, individuals who took coffee in the late part of the day did not demonstrate equal benefits. This is why researchers think that the intake of coffee in the morning can work in synchronisation with the body’s natural cycles to decrease inflammation and improve heart function.
Coffee may help protect against alzheimer’s and parkinson’s disease
An article published as a research paper titled “Frontiers in Neuroscience” reveals that there are certain components in coffee, besides caffeine, which are beneficial for brain health. Canadian scientists have isolated these components, which are known as “phenylindanes.” These are produced through a chemical reaction that occurs while coffee beans are being roasted. These components stop the buildup of tau and beta-amyloid proteins, which are linked to Alzheimer’s and Parkinson’s diseases. Additionally, it was discovered that dark-roasted coffees tend to have higher concentrations of phenylindanes, which reveal a higher neuroprotective value.
Moderate coffee consumption is associated with longer life
In one of the biggest research studies ever done involving coffee and longevity, which was published in the Annals of Internal Medicine, 171,616 participants in the UK Biobank study were observed. Those who drank 1.5 to 3.5 cups of coffee every day were shown to have a 30 percent reduced risk of death compared with those who drank coffee.Both caffeinated and decaffeinated coffee consumption was found to be beneficial. For individuals who had added sugar to their coffee, the effects remained similar, but for aspartame, it remained uncertain.
Coffee intake reduces the risk of heart disease
There are many studies that have proven the protective effect of coffee on the cardiovascular system. The Framingham Heart Study, which included 5,209 participants, showed that the increased consumption of coffee per day led to a reduced risk of heart failure or stroke by 8 per cent.Another research carried out in the journal Heart, with 25,000 participants, found moderate coffee drinking to be associated with a reduced risk of early symptoms of heart disease.
Even high coffee intake shows protective effects
In a large study of 500,000 participants based in the UK, published in JAMA Internal Medicine, results revealed that coffee consumers had a 10 to 15 percent reduced risk of death over a period of 10 years compared to non-coffee consumers.It is especially important to note that this protective association persisted even among those drinking eight or more cups daily. Additionally, scientists found that coffee seemed to mitigate some adverse effects associated with smoking and alcohol consumption.
Coffee may counteract age-related inflammation
Ageing involves chronic inflammation that leads to many diseases in old age. A research finding by Stanford University demonstrated that caffeine interferes with the chemical processes involved in age-related inflammations. It may slow the biological aging process due to the reduction in inflammatory reactions that occur in the body.
Health benefits increase with age
A Spanish cohort study following 20,000 participants over 10 years found that the health benefits of coffee became more pronounced with age. Adults over 45 years experienced a 30 per cent reduction in mortality risk for every two additional cups of coffee consumed per day.Researchers concluded that as the baseline risk of disease increases with age, the protective effects of coffee become more evident. Taken together, findings from multiple large-scale studies suggest that coffee, when consumed in moderation and preferably earlier in the day, is associated with improved heart health, reduced inflammation, better neurological protection and longer life.
