A recent study has shown that people consuming three to five cups of coffee a day have the lowest risk of clogged arteries and heart attacks.
The latest finding was by the Kangbuk Samsung Hospital, Seoul in South Korea, which examined the link between coffee consumption and the presence of coronary artery calcium (CAC) which is an early indicator of coronary atherosclerosis, when arteries get clogged, leading to heart attack or a stroke. The team studied a group of 25,138 men and women aged in mid-40s had no signsof heart disease.
The researchers estimated the CAC score ratios associated with different levels of coffee consumption compared with no coffee consumption. The calcium ratios were 0.77 for people who had less than one cup per day, 0.66 for those having one to three cups every day, 0.59 for those consuming three to five cups per day, and 0.81 for people having at least five cups or more every day compared with non-coffee drinkers.
The researchers found the prevalence of detectable CAC was 13.4 percent among the whole group of people and the average consumption of coffee was 1.8 cups per day. They say coffee consumption had a possible link to reduced risk of Type 2 diabetes, a strong risk factor for atherosclerosis.
“Coffee consumption might be inversely associated with CVD (cardiovascular disease) risk. Further research is warranted to confirm our findings and establish the biological basis of coffee’s potential preventive effects on coronary artery disease,” the authors concluded.
Coffee had its origin in the Ethiopian highlands, where legend goes that a herd named Kaldi found his goats hyperactive after eating certain berries from a tree andfound it with tasty and inducing alertness. Soon, coffee became the beverage to keep people alert and it made its way across the Arabian Peninsula.
What about tea that is the most consumed liquid in the world next to water and before beer and it has its origins in China dating back to the Emperor of China in 2737 BC while he was boiling water under a tree. When leaves accidentally fell into the boiling water, he tasted it and was surprised by its goodness. Soon, it became the most consumed beverage in the world, as it was first supported by the respected priests class in China and Japan who found it essential to be awake, study and meditate and gave it a spiritual outlook too.
Essentially both beverages — coffee and tea — gained popularity in Asia before the Europeans arrived in the 17th century to make these beverages truly global.
Enter the 21st century, both coffee and tea are competing with each other for a bigger share and fighting it out adverse research reports, if any. Coffee with its caffeine has always been at the receiving end, making coffee boards and lobbyists to harp on its positive benefits while tea constantly retained its edge despite being less tasty with noo caffeine.
Healthwise, the beverages are squarely pitted against each other in terms of sales. Whie the figures below give a glance at half the market size of coffee compared to tea, the need for coffee growers and coffee boards across the globe make it compulsive to gain positive coverage in the media despite its one demerit, that, cancer-causing caffeine is higher in it than tea.
it When you can’t make caffeine’s negative impact on the human body, the best alternative is to highlight its other positive effects on the body, whether short-term or long-term and hence, there is visibly more coffee-related research coming out with positive health benefits in one form or the other.
Besides the South Korean study, some recent findings showed that coffee has the ability to reduce the incidence of dementia or Alzheimer’s or even type 2 diabetes, due to caffeine and another study proved that its higher levels of the stimulant helps people asthma relax by clearing the lung’s airways. Another study showed that it constricts blood vessels in the brain, reducing migraines and keeping away post-drink hangovers in the morning.
Without any explicit advertisement, coffee drinkers know that they can keep off their headache taking an Advil with coffee any time. But, a Harvard School of Public Health nullified all those beliefs by analyzing coffee’s overall effect on health and concluding that the beverage was pretty neutral, in the sense it didn’t have any great virtues, nonetheless any serious health problems. It means whether 5 or 6 cups of coffee made no difference to raise anyone’s risk of dying, nor make it anyone live particularly longer.
Tea, long hailed for its virtues of antioxidants and potential cancer-fighting properties, contatins according to the National Cancer Institute at the NIH, several polyphenol compounds. No conclusive studies have come out whether tea really reduces the risk of cancer, tea advocates have long harped on its therapeutic or medicinal benefits. Polyphenols in green tea, and theaflavins and thearubigins in black tea, with free radicals are touted to be protecting cells from DNA damage. But some tea blends from China, India, or Sri Lanka have been found to contain aluminum and risky amounts of lead.
Which one is better? Coffee or tea?
As long as sugar and cream are avoided with these beverages, ill-effects can be reduced radically, suggest numerous studies leaving us to decide how to economize our habit of drinking these beverages. Both have been serving humans for thousands of years and they remain so for few more.
