Coffee consumers may have one less risk to worry about. A recent study by best known institute suggested that long term and moderate coffee consumption is inversely associated with CVD risk.
Coffee, becoming a popular and social beverage all over the world, particularly in the West, is a drink made from roasted bean from the Coffea plant, native to tropical Africa and Madagascar.
Caffeine, a chemical stimulant found abundantly in tea and coffee is a class of methylxanthine having a profound impact in central nervous system (CNS).
Cardiovascular disease is a medical condition characterized by heart attack, chest pain (angina) or stroke caused by narrow blood vessels induced block blood.
In the review of literature existed from the data base involved prospective cohort studies of the relationship between coffee consumption and CVD risk, 36 satisfied the criteria and guidelines included studies, with 1 279 804 participants and 36 352 CVD cases, coffee drinkers have a nonlinearly inverse association to risk of CVD, depending to numbers of cup intake per day.
According to the joint study lead by the Harvard School of Public Health, the relative risk of cardiovascular disease in coffee consumption was .95 in compared with the 0 cup of coffee consumption per day.
Dr. Ding M, the lead author in the review said, "oderate coffee consumption was inversely significantly associated with CVD risk, with the lowest CVD risk at 3 to 5 cups per day, and heavy coffee consumption was not associated with elevated CVD risk".
In fact, long term moderate coffee consumption not only reduced risk of heart disease, but also ameliorated other conditions associated with CV risk factors such as obesity and depression.
However, the affect of caffeine in lipid file may associate to endothelial function in increased CVD risk, depending to how the coffee is prepared.
More importantly, epidemiological studies also suggest that risks of mortality in both CV and all-causes are substantially attenuated in regular coffee drinkers.
Furthermore, other researchers insisted that the health benefits of coffee consumption regarding to cardiovascular system risk, mostly depend on its antioxidant compounds involved many factors, such as variety of coffee species, roasting degree, type of brewing method and serving size.
Antioxidant is types of chemical compound inhibited the free radicals to protect the body against oxidative damage cause of cellular dysfunction which has been found to increased risk of metabolic syndrome epidemiologically, a major risk factor of CVD development.
Some searchers concerned that caffeine as a brain stimulant after intake, may stimulate the sympathetic nervous system, inducing rise of blood pressure, release of adrenaline and increased heart beat harder and faster that may cause enormous problem to people with precondition of CVD.
However. for healthy individuals, coffee and coffee caffeine have a reduced prevalence of CVD incidence
Since most of the data on coffee's health effects are based on observational data, risk of high caffeine adverse effects such as anxiety, insomnia, tremulousness, and palpitations have rarely be mentioned, therefore, more randomized, controlled studies are necessary, some researchers suggested.
