Täh? Eikös ne "huonot rasvat" ole juuri niitä, jotka ovat vastuussa monista kahvin positiivisista terveysvaikutuksista? Tässä mielessä suodatinkahvi on lähes poispilattua...

Does a latte a day keep the hepatologist away?

Several studies have demonstrated that the protective effect of coffee on liver disease is independent of caffeine or that consumption of other caffeine-containing beverages such as green tea have no consistent association with liver enzymes, cirrhosis, or liver cancer. Substances found in coffee, including chlorogenic acids and diterpenes, have been shown to have antioxidative and anticancer properties in several animal and cell-culture experiments. The diterpenes, cafestol and kahweol, block enzymes involved in the detoxification of carcinogens and induce synthesis of glutathione. However, these oils are trapped by filter paper and are found in negligible amounts in filtered coffee, the predominant form of brewing in most of the populations studied.

No, itse tulee nautittua kahvi lähes aina espressoautomaatin keittämänä ja siten kaikki "tärpätit" tallella.

Tästä perspektiivistä:

The coffee culprit 
Although caffeine is often cast as a villain, the stimulant is not to blame for unfiltered coffee's effect on cholesterol levels. According to Klag, the increase in cholesterol is believed to be caused by oils called terpenes that are found in coffee, but are mostly removed by filters.

"Persons who drink unfiltered coffee should get their cholesterol checked to make sure it is not elevated," says Klag.

The Johns Hopkins researcher notes that in a 1994 study he and his colleagues found an association between coffee consumption and an increased risk of heart disease. But most of the increased risk was linked to coffee drinking before 1975. It was during the mid-1970s, Klag points out, that drip coffee makers became widely used in the United States, making filtered coffee the norm.

Although Klag advises his patients who drink unfiltered coffee to switch to filtered brew, he says that not everyone needs to be overly concerned about the effect of unfiltered coffee on cholesterol. He notes that cholesterol levels are a "combination of how you live, what you eat and what genes you inherit." A healthy person with low cholesterol probably does not need to worry too much about the effect of coffee on cholesterol levels, he says.

A Dutch researcher who has also documented the cholesterol-boosting effect of unfiltered coffee agrees that the risks need to be seen in perspective.

"Unfiltered coffee has much less effect on your heart disease risk than smoking, high blood pressure or being overweight," says Dr. Martijn B. Katan, a professor at the Wageningen Center for Food Sciences and Wageningen University. "But if you want to optimize your cholesterol levels, you should avoid large daily amounts of unfiltered coffee."

Unfiltered coffee seems to boost cholesterol the most, although a handful of recent studies hint that filtered coffee may have an effect on cholesterol, too. In one study, researchers in Sweden found that people who normally drank filtered coffee experienced a small drop in cholesterol levels when they stopped drinking coffee for a few weeks. The results were "surprising," according to Dr. Elisabeth Strandhagen, of Sahlgrenska University Hospital(CK) in Goteborg, who led the study.

"We have done some tests on coffee filters, but we cannot explain why the filtered coffee had this effect on serum cholesterol," she says.

Despite the findings, filtered coffee seems to have a much smaller effect on cholesterol than unfiltered coffee. Strandhagen encourages people with high cholesterol or who are at high risk of heart disease to choose filtered coffee. They should also avoid coffee filters that have "aroma holes," which are very common in Sweden, she says.

Tilanne ei ole vielä mitenkään selvä "tärpättien" suhteen eikä muutamasta "pannukahvi tappaa" -tutkimuksesta kannata vielä vetää kovin pitkälle meneviä johtopäätöksiä:

Coffee consumption and risk of coronary heart diseases: A meta-analysis of 21 prospective cohort studies

However, there was no sub-analysis stratified by boiled and filter coffee in the cohort studies involved in this study. We could not determine if the long-term effect of filter coffer differed from boiled coffer on CHD development in this meta-analysis. Further studies were needed to clarify this issue.

Results: From the subjects included in the study, 87% consumed a boiled Greek type of coffee. Moreover, 40% had a ‘low’, 48% a ‘moderate’ and 13% a ‘high’ daily coffee consumption. There was a linear increase in FMD according to coffee consumption (‘low’: 4.33 ± 2.51% vs ‘moderate’: 5.39 ± 3.09% vs ‘high’: 6.47 ± 2.72%; p = 0.032). Moreover, subjects consuming mainly a boiled Greek type of coffee had a significantly higher FMD compared with those consuming other types of coffee beverages (p = 0.035).

"Yleinen näkemys" on että suodatin olis parempaa mutta se näkemys tosiaan tulee pitkälti tuosta kolesterolivinkkelistä, tilanne voi muuttua/olla erilainen jos asiaa tutkitaan "eri kulmista ja eri mittauksin". Nämä indikaatiot elää ajan ja tutkimustulosten kertyessä joten tilanne voi muuttua. Sekin olisi mukava nähdä onko esim kahvin jauhatuksen tuoreudella merkitystä. Esim onko tuo Kreikkalainen kahvi jauhettu "kahvipavuista" aina suoraan käyttöä varten ja siten parempaa vaikutuksiltaan?

Kyllähän se kokonaisvaikutus on edelleen pannukahvillakin "nykyisen konsensus näkemyksen" mukaan myönteinen terveyden suhteen jos pysytään tuossa 3-5 kuppi päivässä. Liikaa ei kannata litkiä...

Seurataan tilannetta. 

Tuossa hieman kreikkalaisesta  kahvista; vaalea paahto ja erittäin hieno jauhatus. voisi olettaa että antioksidantteja säilyy vaaleassa paahdossa enemmän ja irtoaa hienosta jauhatuksesta paremmin joten etu voi tulla suuremmasta antioksidanttien kokonaismäärästä tuossa kreikkalaisessa kahvissa. Ei niinkään siinä että se olisi pannutyyppisesti valmistettu? Nämä kaikki pitäisi vertailla.

Be sure to use Greek coffee, which is a light-roast coffee and is very finely ground. It can be found at most Greek grocers.

Tutkimusta paahdon vaikutuksista kahvin pro-ja antioksidantteihin.

New research into health benefits of coffee

New research has brought us closer to being able to understand the health benefits of coffee.

Monash researchers, in collaboration with Italian coffee roasting company Illycaffè, have conducted the most comprehensive study to date on how free radicals and antioxidants behave during every stage of the coffee brewing process, from intact bean to coffee brew.

The team observed the behaviour of free radicals - unstable molecules that seek electrons for stability and are known to cause cellular and DNA damage in the human body - in the coffee brewing process. For the first time they discovered that under certain conditions coffee can act as an antioxidant, a compound found in foods that helps stabilise free radicals.

The findings, published in PLOS ONE, will lead to a deeper understanding of the brewing process, as well as the potential health benefits of coffee.

Siis - meillä on metatutkimus, jonka mukaan sydäntautien suhteen ei löydy eroa suodattamattoman ja suodatetun kahvin välillä ja sitten meillä on hajanainen joukko tutkimuksia, joiden mukaan suodattamaton kaffe nostaa veren (pahaa) kolesterolia?

Minun mielestäni tässä ei ole mitään ristiriitaa - kokonaisuus kuitenkin ratkaisee loppupelissä ja vaikka suodattamaton kahvi nostaisikin pahaa kolesterolia, niin hyödyt lienevät suuremmat. Lisäksi - vaikka en mitenkään liputa "vedetään vaan kaikessa rauhassa pekonia ja voita niin, että napa paukkuu" -kolesterolirevisionismin puolesta - niin kyllähän se toinenkin "virallisen terveysvalistuksen" ääripää on alkanut osoittautumaan vähintäänkin himppasen överiksi vedetyksi. Ainakin ison veden tuolla puolen mm. kanamunat, katkaravut ja sen sellaiset ovat jo vapautuneet pannasta - ja siten kysymys siitä, että mikä merkitys ravitsemuksella ja kolesterolilla an sich on sairastuvuuteen lienee kuitenkin relevantti vaikka täällä monien mielestä "science is settled" tässäkin tapauksessa.

Lainataan tähän alle se koko kappale. Lainasit aiemmin hyvin valikoiden, kuten tekstistä huomaat tässä meta-analyysissä ei ole riittävällä tarkkuudella pyritty erottelemaan filtteroitua kahvia pannukahvista.

Tämä oli meta-analyysin pääkohta/"tavoite"  ja naisilla hyöty näyttää olevan selvempi kuin miehillä: 

Conclusion

Our findings do not support the hypothesis that coffee consumption increases the long-term risk of coronary heart disease. Habitual moderate coffee drinking was associated with a lower risk of CHD in women.

Sitten näistä oletetuista/havaituista riskeistä: 

.

1. Mechanisms of coffee on CHD risk

Coffee consumption may have duplex effects on cardiovascular system. Mechanisms of how coffee cause or protect against CHD have recently been reviewed in details by Cornelis and El-Sohemy [46]. In brief, coffee consumption may increase the CHD risk by increasing serum cholesterol and homocysteine, blood pressure, endothelial dysfunction and aortic stiffness [47][48] and [49]. The cholesterol-raising effect is probably influenced by the brewing method [47].

Boiled coffee contains cafestol and kahweol that powerfully elevate the levels of serum total and LDL cholesterol [48]. These substances were largely trapped by the use of paper filter in coffee preparation [48]. Thus, the filter coffee may be a weaker association, if any, with the cholesterol level. A case–control studied also reported a lower relative risk of non-fatal myocardial infarction in filter coffee consumers than those drinking boiled coffee [50].

These findings suggested that the type of coffee drinking in different countries, or even in the same country, may partly explain the conflicting results of the studies. Among the 21 cohort studies included in this meta-analysis, six cohort studies (U.S. 3, European 3) reported that filter brewing was the predominant method[16][19][25][26] and [51]. Klag et al. (U.S.) [18] and Kleemola et al. (Finland) [23] reported that their subjects mainly consumed percolated coffee or unfiltered coffer. Two articles mentioned an increased proportion of filtered coffee consumption [23] and [25]. However, there was no sub-analysis stratified by boiled and filter coffee in the cohort studies involved in this study. We could not determine if the long-term effect of filter coffer differed from boiled coffer on CHD development in this meta-analysis. Further studies were needed to clarify this issue.

Ja kuten viimeinen lause yllä osittaa filtterikahvin ja pannukahvin välinen kisa ratkaistaan muissa/jatkotutkimuksissa.  

Association of boiled and filtered coffee with incidence of first nonfatal myocardial infarction: the SHEEP and the VHEEP study. CONCLUSIONS:

Consumption of boiled coffee appears to increase the incidence of first nonfatal myocardial infarction. This increased incidence is consistent with randomized trials showing an adverse impact of boiled coffee on blood lipids.

Caffeine intake associated with reduced levels of erectile dysfunction

Men who drink the equivalent caffeine level of two to three cups of coffee a day are less likely to have erectile dysfunction (ED), according to researchers from The University of Texas Health Science Center at Houston (UTHealth).

The results of a study published recently in PLOS ONE found that men who consumed between 85 and 170 milligrams of caffeine a day were 42 percent less likely to report ED, while those who drank between 171 and 303 milligrams of caffeine a day were 39 percent less likely to report ED compared to those who drank zero to seven milligrams a day. This trend was also true among overweight, obese and hypertensive men.

"Even though we saw a reduction in the prevalence of ED with men who were obese, overweight and hypertensive, that was not true of men with diabetes. Diabetes is one of the strongest risk factors for ED, so this was not surprising," said David S. Lopez, Dr.P.H., M.P.H., lead author and assistant professor at UTHealth School of Public Health.

Kahvin suurin luomuvastainen riski on tietysti se, että

Viimesimpiä koosteita.

The ISIC session report highlights the research presented at a Satellite Symposium held during the European Association for Cardiovascular Prevention & Rehabilitation's 2015 congress in Lisbon, Portugal, on the subject of 'Coffee and CVD Mortality'. Leading researchers in this field presented on the role of lifestyle factors in CVD mortality risk reduction, the epidemiological evidence on coffee and CVD mortality, and the conclusions from meta-analyses on coffee and CVD mortality.

Key highlights:

The lowest CVD mortality risk is seen at an intake of approximately 3 cups of coffee per day, with a percentage risk reduction of up to 21%.

Two 2014 meta-analyses suggest an association between coffee consumptionand CVD risk, proposing a 'U-shaped' pattern whereby optimal protective effects were achieved with 3-5 cups of coffee per day.3,4

Drinking 3-4 cups of coffee per day is associated with an approximate 25% lower risk of developing type 2 diabetes compared to consuming none or less than 2 cups per day.

People with diabetes typically have a higher CVD mortality risk, therefore this association may be linked to a decreased CVD risk.6 

In males, a combination of 5 healthy behaviours (a healthy diet, moderate alcohol consumption (10 to 30 g/ day), no smoking, being physically active and having no abdominal adiposity) could prevent 79% of myocardial infarction events.7 

Half of CVD cases in women could be avoided by modifying lifestyle choices, as approximately 73% of CHD cases and 46% of clinical CVD are attributable to an unhealthy lifestyle.8

The report concludes that recent research supports the view that moderate coffee consumption at approximately 3 - 5 cups per day may have a protective effect against CVD mortality risk.

The mechanisms of action behind the associations are unclear, however areas of interest for future research include the anti-inflammatory and antioxidant properties of coffee, and the known association between coffee consumption and type 2 diabetes risk reduction as CVD mortality is typically higher in this group. It is important to note that results differ between varying populations; it is suggested that 2 cups of coffee per day may offer the greatest protection in a Japanese population, whilst 3 cups may provide the greatest protection in UK and US populations.

Itse en juo kahvia laisinkaan, enkä syö esim. hedelmiä juuri ollenkaan. Yritän pysyä ruoan suhteen kotimaisessa. Siihen tosiaan ainakin pyrin.

Nykyinen suositus on 5-7 annosta kasviksia ja hedelmiä päivässä. Ei kannata siitä luistaa jonkun ideologian takia.

Voisi jopa väittää että tämä on tärkein yksittäinen suositus ravintosuosituksissa kokonaisterveyden kannalta.

Tuoretta, Assososiaatioita.

"People who drink about three to five cups of coffee a day may be less likely to die prematurely from some illnesses than those who don’t drink or drink less coffee, according to a new study by Harvard T.H. Chan School of Public Health researchers and colleagues. Drinkers of both caffeinated and decaffeinated coffee saw benefits, including a lower risk of death from cardiovascular disease, neurological diseases, type 2 diabetes, and suicide.

“Bioactive compounds in coffee reduce insulin resistance and systematic inflammation,” said first author Ming Ding, a doctoral student in theDepartment of Nutrition. “That could explain some of our findings. However, more studies are needed to investigate the biological mechanisms producing these effects.”

Researchers analyzed health data gathered from participants in three large ongoing studies: 74,890 women in the Nurses’ Health Study; 93,054 women in the Nurses’ Health Study 2; and 40,557 men in the Health Professionals Follow-up Study. Coffee drinking was assessed using validated food questionnaires every four years over about 30 years. During the study period, 19,524 women and 12,432 men died from a range of causes.

In the whole study population, moderate coffee consumption was associated with reduced risk of death from cardiovascular disease, diabetes, neurological diseases such as Parkinson’s disease, and suicide. Coffee consumption was not associated with cancer deaths. The analyses took into consideration potential confounding factors such as smoking, body mass index, physical activity, alcohol consumption, and other dietary factors.

This study provides further evidence that moderate consumption of coffee may confer health benefits in terms of reducing premature death due to several diseases,” said senior author Frank Hu, professor of nutrition and epidemiology. “These data support the 2015 Dietary Guidelines Advisory Report that concluded that ‘moderate coffee consumption can be incorporated into a healthy dietary pattern.’”

"Association of Coffee Consumption With Overall and Cause-specific Mortality in a Large US Prospective Cohort Study

Abstract

Concerns about high caffeine intake and coffee as a vehicle for added fat and sugar have raised questions about the net impact of coffee on health. Although inverse associations have been observed for overall mortality, data for cause-specific mortality are sparse. Additionally, few studies have considered exclusively decaffeinated coffee intake or use of coffee additives. Coffee intake was assessed at baseline by self-report in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Hazard ratios were estimated using Cox proportional hazards models. Among 90,317 US adults without cancer at study baseline (1998–2001) or history of cardiovascular disease at study enrollment (1993–2001), 8,718 deaths occurred during 805,644 person-years of follow-up from 1998 through 2009. Following adjustment for smoking and other potential confounders, coffee drinkers, as compared with nondrinkers, had lower hazard ratios for overall mortality (<1 cup/day: hazard ratio (HR) = 0.99 (95% confidence interval (CI): 0.92, 1.07); 1 cup/day: HR = 0.94 (95% CI: 0.87, 1.02); 2–3 cups/day: HR = 0.82 (95% CI: 0.77, 0.88); 4–5 cups/day: HR = 0.79 (95% CI: 0.72, 0.86); ≥6 cups/day: HR = 0.84 (95% CI: 0.75, 0.95)). Similar findings were observed for decaffeinated coffee and coffee additives. Inverse associations were observed for deaths from heart disease, chronic respiratory diseases, diabetes, pneumonia and influenza, and intentional self-harm, but not cancer. Coffee may reduce mortality risk by favorably affecting inflammation, lung function, insulin sensitivity, and depression."
