Red wine good, tea OK, power drinks bad, right? Well, together is so frequently the case, the prize isn"t always quite together black and also white as we can think, as a series of new studies reminds us. The studies, in addition to many others, were presented at the European culture of Cardiology in Barcelona, Spain over the weekend.

You are watching: Is there caffeine in red wine

Red wine

Here"s the an excellent news abouy red wine: it protects against cariovascular disease. But here"s the rest of the story: it just works that method for people who exercise, follow to outcomes from the In Vino Veritas (IVV) examine presented at ESC congress by Professor Milos Taborsky from the Czech Republic.

Evidence saying that mild come moderate usage of alcohol protects versus cardiovascular condition has been accumulating since the early 1990s. In particular, retrospective studies have found that wine rises levels the HDL, the "good" cholesterol. Yet until currently there has been no long-term, prospective, randomized research comparing the results of red and also white alcohol on HDL cholesterol and other markers of atherosclerosis.

That"s what Prof. Taborsky and also associates set out come test. The results: "We uncovered that middle wine drink was only protective in civilization who exercised. Red and also white wine developed the very same results."

The study had 146 human being with mild come moderate threat of cardiovascular disease according to the HeartScore. Participants were randomized come one year the moderate usage of red wine (Pinot Noir) or white wine (Chardonnay-Pinot) indigenous the same year and also wine region of the Czech Republic.

"The only positive and constant result was in the subgroup the patients who took much more exercise, which means regular exercise at least twice a week, plus the wine consumption. ... There might be part synergy in between the low dose the ethyl alcohol in wine and also exercise i m sorry is protective versus CVD."

Spot the tea then?

So how about tea matches coffee? drink tea reduces non-cardiovascular mortality through 24%, reveals a study of 131,000 world presented through Professor Nicolas Danchin indigenous France.

"If you need to choose in between tea or coffee it"s probably much better to drink tea," Danchin. "Coffee and tea space important contents of our means of life. Their impacts on cardiovascular health have been investigated in the past with sometimes divergent results. Us investigated the results of coffee and also tea on CV mortality and also non-CV mortality in a big French populace at low hazard of cardiovascular diseases."

Tea had actually a more marked effect on blood pressure than coffee, with a 4-5 mmHg to decrease in SBP and 3 mmHg decrease in DBP in the heavy tea drinkers, contrasted to non-drinkers, when changed for age.

Coffee showed a tendency for enhancing CV mortality in the heavy contrasted to non-drinkers but the result was not significant. Coffee substantially increased non-CV mortality however the raised risk disappeared when the effect was adjusted for smoking. Danchin said: "The tendency for greater mortality in coffee drinkers is most likely largely explained by the reality that there are more smokers in the group who drink a the majority of coffee."

He concluded: "Tea has antioxidants i m sorry may administer survival benefits. Tea drinkers likewise have healthy lifestyles so does tea drinking reflect a particular person file or is that tea, every se, that improves outcomes -- for me that remains an open question. Pending the answer to that question, ns think the you could fairly honestly introduce tea drinking fairly than coffee drinking and even quite than not drinking anything at all."

Skip the power drinks

But while the wine, tea and coffee group can find both encouraging and also discouraging elements in the latest research, that"s no the case with energy drinks, i m sorry French Professor Milou-Daniel Drici identified as attention for many consumers.

"So-called "energy drinks" are famous in run clubs and also during physics exercise, with people sometimes consuming a variety of drinks one after the other. This situation can cause a variety of adverse conditions including angina, cardiac arrhythmia (irregular heartbeat) and even suddenly death," Drici said.

"Around 96% the these drinks contain caffeine, with a typical 0.25 litre can holding 2 espressos precious of caffeine. Caffeine is among the most potent agonists that the ryanodine receptors and leads to a massive release the calcium within cardiac cells," he said, presenting the results of a study which uncovered 95 situations of cardiovascular problems linked to power drinks end a two-year duration in France.

"We discovered that "caffeine syndrome" was the most usual problem, developing in 60 people. That is characterised by a quick heart rate (called tachycardia), tremor, anxiety and also headache," Drici said. "Rare yet severe adverse occasions were likewise associated through these drinks, such together sudden or unexplained death, arrhythmia and heart attack (myocardial infarction). Our literature search evidenced that these conditions can be associated to consumption of energy drinks."

Drici added: "The basic public require to know that so-called "energy drinks" have actually absolutely no place during or after physical exercise, as compared with various other drinks draft for the purpose. When supplied in lengthy alcoholic cocktails, the caffeine in "energy drinks" allows young human being in dance clubs or elsewhere to overcome the unwanted results of alcohol, causing an even greater entry of caffeine."

The European culture of Cardiology (ESC) represents much more than 80 000 cardiology professionals across Europe and also the Mediterranean. That mission is to alleviate the burden of cardiovascular an illness in Europe.
