தினமும் 5 கப் காபி குடிங்க….மாரடைப்புக்கு டாட்டா சொல்லுங்க

Featured Replies

drink_coffee_001.jpgதினமும் 5 கப் காபி குடித்தால் மாரடைப்பு வராது என்று ஆய்வு ஒன்றில் தெரிவிக்கப்பட்டுள்ளது.

உடலுக்கு உற்சாகம் தரும் பானங்களில் ஒன்றான காபி மற்றும் டீ குறித்து எதிர்மறையான கருத்துக்கள் நிலவி வருகின்றன.

இந்நிலையில், தென்கொரியா தலைநகர் சியோவில் உள்ள ஒரு தனியார் மருத்துவமனையை சேர்ந்த நிபுணர்கள் சமீபத்தில் இதுகுறித்து ஆய்வு நடத்தினார்கள்.

பொதுவாக ரத்த நாளங்களில் கடின தன்மை அல்லது ரத்து குழாய்கள் சுரங்குவதால் அடைப்பு ஏற்படும்.

அதனால் ரத்த ஓட்டம் சீராக இல்லாமல் மாரடைப்பு மற்றும் பக்கவாதம் போன்றவை ஏற்படுகிறது. ஆனால் தினமும் 3 முதல் 5 கப் காபி குடிப்பவர்களுக்கு மாரடைப்பு உள்ளிட்ட இதய நோய்கள் ஏற்படும் வாய்ப்பு மிகவும் குறை என கண்டறிந்துள்ளனர்.

காபியில் உள்ள வேதி பொருட்கள் ரத்த நாளங்களில் உள்ள அடைப்பை நீக்கி ரத்த ஓட்டம் சீராக ஓட வழிவகை செய்கின்றன. அதனால் மாரடைப்பு ஏற்படுவதில்லை என தெரிவிக்கப்பட்டுள்ளது.

Drinking a few cups of coffee a day may help people avoid clogged arteries - a known risk factor for heart disease - Korean researchers believe.

They studied more than 25,000 male and female employees who underwent routine health checks at their workplace.

Employees who drank a moderate amount of coffee - three to five cups a day - were less likely to have early signs of heart disease on their medical scans.

The findings reopen the debate about whether coffee is good for the heart.

Heart effects

There is a lot of confusion when it comes to the effect of coffee on heart health.

Some studies have linked consumption to heart risk factors, such as raised cholesterol or blood pressure, while others suggest the beverage may offer some heart protection.

But there is no conclusive evidence either way, and the latest research from South Korea, which is published in the journal Heart, only adds to the discussion.

Unexplained link

In the study, the researchers used medical scans to assess heart health.

Specifically, they were looking for any disease of the arteries supplying the heart - the coronary arteries.

More research is needed to confirm these findings and understand what the reason is for the association”

Victoria Taylor of the British Heart Foundation

In coronary heart disease, the coronary arteries become clogged by the gradual build-up of fatty material within their walls.

The scan the researchers used looks for tiny deposits of calcium in the walls of the coronary arteries to provide an early clue that this disease process may be occurring.

None of the employees included in the Korean study had outward signs of heart disease, but more than one in 10 of them were found to have visible calcium deposits on their scans.

The researchers then compared the scan results with the employees' self-reported daily coffee consumption, while taking into account other potential heart risk factors such as smoking, exercise and family history of heart problems.

People who drank a few cups of coffee a day were less likely to have calcium deposits in their coronary arteries than people who drank more than this or no coffee at all.

The study authors say more research is needed to confirm and explain the link.

Coffee contains the stimulant caffeine, as well as numerous other compounds, but it's not clear if these might cause good or harm to the body.

Victoria Taylor of the British Heart Foundation said: "While this study does highlight a potential link between coffee consumption and lower risk of developing clogged arteries, more research is needed to confirm these findings and understand what the reason is for the association.

"We need to take care when generalising these results because it is based on the South Korean population, who have different diet and lifestyle habits to people in the UK."
