:) All of these studies they do are so silly.. Every year they change their mind on what effect everything has on out bodies.. some years its good, some its bad.. This is the latest coffee study

Regular coffee drinkers have 'cleaner' arteries

 

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.

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.

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."

 

How much caffeine?

 

coffee beans

In the US, experts say up to 400mg a day appears to be safe for most healthy adults

There is no recommended daily upper limit for caffeine consumption in the UK, except for pregnant women

If you're pregnant, you should limit the amount of caffeine you have to 200mg a day - equivalent to two mugs of instant coffee

one mug of instant coffee: 100mg

one mug of filter coffee: 140mg

one mug of tea: 75mg

one can of cola: 40mg

an espresso contains about 50mg of caffeine

Coffee shop caffeine levels vary widely

Definitely not true for me.

 

I took a 750ml flask of strong java to work every day for years.

2 years ago I started getting atrial fibrillation - irregular heartbeat.....caused by my caffeine intake.

I stopped the coffee and the fibrillation hasn't bothered me once since, BUT as part of the investigation into my heart they gave me a scan; which found I had 50% plaque in at least one artery and more elsewhere.

Admittedly this isn't nearly bad enough for them to have to do something - yet. I am 60.

 

Would it have been worse without me drinking the stuff everyday for 12 years?

 

Doubt it. It might have been better without all that beer though....and the rest. [smile]

 

Cheers!

Sounds like a selection bias to me. Thousands of Koreans can be studied but it would be difficult to extrapolate to caucasians.

 

I drink tons of coffee and had a terrible calcium score (bottom 10%).

 

Coffee has a beneficial effect on diabetes though. Pretty complex relationships there I'm afraid.

In the big poker tournament with the grim reaper, that's one hand I know I'm never going to win.

So why bother trying.

 

Now if you'll exuse me, I'm going to finish off this big mug of double spooned coffee while lighting up my Habana bad boy wrapped in fatty bacon rind.
