Here is abstract of that coffee study.. I don't see where they made

any distinction b/w filtered and unfiltered.

http://www.ajcn.org/cgi/content/abstract/80/4/862

Associations between coffee consumption and inflammatory markers in

healthy persons: the ATTICA study1,2,3

Antonis Zampelas, Demosthenes B Panagiotakos, Christos Pitsavos,

Chrysohoou and Christodoulos Stefanadis

1 From the Department of Nutrition and Dietetics, Harokopio

University, Athens, Greece (AZ and DBP); and the First Cardiology

Clinic, School of Medicine, University of Athens, Greece (CP, CC, and

CS).

Background: The effect of coffee consumption on the cardiovascular

system is conflicting. Inflammation is important to the development

of cardiovascular disease (CVD), and several dietary factors are

thought to exert significant effects on inflammation and thus on the

risk of CVD.

Objective: We aimed to investigate the associations between coffee

consumption and inflammatory markers.

Design: The cross-sectional survey enrolled 1514 men ( ± SD age: 46 ±

13 y; range: 18–87 y) and 1528 women (aged 45 ± 13 y; range: 18–89

y). Five percent of men and 3% of women were excluded for history of

CVD. Fasting blood samples were collected. Dietary habits (including

consumption of various types of coffee) were evaluated by using a

validated food-frequency questionnaire.

Results: Compared with coffee nondrinkers, men who consumed >200 mL

coffee/d had 50% higher interleukin 6 (IL-6), 30% higher C-reactive

protein (CRP), 12% higher serum amyloid-A (SAA), and 28% higher tumor

necrosis factor (TNF-) concentrations and 3% higher white blood cell

(WBC) counts (all: P < 0.05). Women who consumed >200 mL coffee/d had

54% higher IL-6, 38% higher CRP, 28% higher SAA, and 28% higher TNF-

concentrations and 4% higher WBC counts (all: P < 0.05) than did

coffee nondrinkers. The findings were significant even after control

for the interactions between coffee consumption and age, sex,

smoking, body mass index, physical activity status, and other

covariates.

Conclusions: A relation exists between moderate-to-high coffee

consumption and increased inflammation process. This relation could

explain, in part, the effect of increased coffee intake on the

cardiovascular system.

Quote from the original cited article:

" The report did not identify which coffee ingredients caused the

increased risk but Prof Zampelas said the suspicion was that

cafestol and kahweol, found in unfiltered coffee, were to blame. "

Hi :

Well where do you get that information from? The article only says

that it is *suspected* that that is the source of the problem: " Prof

Zampelas said the suspicion was that cafestol and kahweol, found in

unfiltered coffee, were to blame. "

This study had a fairly large number of subjects. What proportion of

the population drinks unfiltered coffee? Fairly low I would have

thought. So a smallish proportion of the population drinking

unfiltered coffee is supposed to cause a noticeable effect on the

data for the entire sample? If that is the case then cafestol and

kahweol must be pretty nasty stuff.

Maybe. But maybe not. Since the phenomenon is noticeable in the

entire sample perhaps it is some other component? No doubt we will

know in a couple of years.

I drink coffee. But not lots of it.

Hi All,

For your interest is the following, for which the pdf

is available.

I would have categorized the curve as reverse-L-

Shaped for the all-cause mortality, which to me is

the bottom line.

Arch Intern Med. 2000 Dec 11-25;160(22):3393-400.

Coffee consumption and the risk of coronary heart disease and death.

Kleemola P, Jousilahti P, Pietinen P, Vartiainen E, Tuomilehto J.

.... coronary heart disease (CHD) ... 20 179 randomly

selected eastern Finnish men and women aged 30 to 59 years who

participated in a

cross-sectional risk factor survey in 1972, 1977, or 1982. ...

followed up for 10

years ... Multivariate analyses were performed by using the

proportional

hazards model. RESULTS: In men, the risk of nonfatal myocardial

infarction was

not associated with coffee drinking. The age-adjusted association of

coffee

drinking was J shaped with CHD mortality and U shaped with all-cause

mortality.

The highest CHD mortality was found among those who did not drink

coffee at all

(multivariate adjusted). Also, in women, all-cause mortality

decreased by

increasing coffee drinking. The prevalence of smoking and the mean

level of

serum cholesterol increased with increasing coffee drinking. Non-

coffee drinkers

more often reported a history of various diseases and symptoms, and

they also

more frequently used several drugs compared with coffee drinkers.

CONCLUSIONS:

Coffee drinking does not increase the risk of CHD or death. In men,

slightly

increased mortality from CHD and all causes in heavy coffee drinkers

is largely

explained by the effects of smoking and a high serum cholesterol

level.

PMID: 11112231 [PubMed - indexed for MEDLINE]

The amount of all-cause death due to coffee, where 1 cup = 100 mg

caffeine, was:

Cups, value (confidence interval)

< 1, 1.58 (1.20-2.07)

1-3, 1.00

4-7, 0.97 (0.82-1.14)

> 7, 1.01 (0.84-1.22)

Hi All,

I have always held the view that coffee drinking is

more or less neutral in its all-cause death, which

to me is the bottom line.

This seems to be the overall finding in the literature,

irrespective of our weight, as an indicator of our level

of CR.

For evidence, see:

Now, it seems, along comes an article that may

be less relevant, since it is an epidemiology study.

CR purportedly reduces inflammation and its markers.

Yet the pdf-available below implies coffee counters

at least inflammation markers:

The findings were significant even after control for the interactions

Hi :

So to clarify, are you saying that the results of the greek study may

only apply to Greece because a much higher proportion of the coffee

drunk in Greece is unfiltered? Thanks.
