To make it clear: coffee is not carcinogenic
Coffee drinkers can breathe a sigh of relief: The world health organization see contrary to earlier Reports, no evidence that coffee can cause cancer. Unless he is very hot.

Favourite drink of the German
Not beer the most popular drink in Germany, is – no, it’s the coffee!
Every German drinks on average 149 liters of coffee per year, equivalent to approximately three cups per day. Place two water. Beer, the German seems to like it that way, but the consumption is on the decline, but still at 100 litres per capita and year. -
A stimulating effect on the body and brain
Coffee contains caffeine. This chemical substance increases the heart rate, expanded blood vessels in the body, but narrows the blood vessels in the brain. Caffeine increases drive efficiency, and concentration and keeps you awake longer. However, you can make coffee, dependent, withdrawal symptoms, for example headache.

Better than its reputation
Coffee is not unhealthy. Every day four or more cups are even good for the body, says the German Green cross, an organization for health care. Because coffee stimulates many organs. As studies show, coffee can lower the risk for diseases such as liver cirrhosis, Alzheimer’s disease and Parkinson’s disease.

It all starts with the coffee cherry
Its origin of the coffee in the East African country of Ethiopia. From there, the coffee plants, up to four-Meter-high shrubs. They form fruits, the coffee cherries. While you Mature, changes its color from green over yellow to red. They contain two seeds: the coffee beans.

Harvest and preparation
The coffee cherries are usually picked by Hand and then dried. They are designed for several weeks in the sun and turned regularly. Or previously cleaned with water and a fermentation process from your flesh. At the end of the bean remains.

Finished the bean is!
After drying, the beans have to be freed only from your cuticle. They are then roasted and finally ground. Depending on the coffee plant different varieties of coffee: Arabica emerge-coffee comes from the Coffea arabica Plant and Robusta coffee is from Coffea canephora.

Brazil’s coffee exporter number 1
Coffee trees need a balanced climate without extremes of temperature, no Frost and scorching heat. Coffee is cultivated worldwide in countries around the Equator. The largest coffee producer is clearly Brazil, followed by Vietnam and Colombia.

Envelope In Hamburg
Each year, the world harvested about eight million tonnes of coffee beans. The majority is exported. The port of Hamburg is the largest European import port for green coffee beans, and a hub for the German, Scandinavian and Eastern European market.

Bad for biodiversity
Traditionally coffee plants were grown in the shade of larger trees, making natural habitats and species diversity remained largely intact. But the global coffee consumption is growing. In order to increase the yield of plants, most of the plantation owners of coffee trees as a monoculture. Especially birds suffer because they will find no shelter.
-
Alternative Eco-Coffee
In many countries, the forest must give way to make room for new coffee plantations. Pesticides and herbicides should also keep pests and weeds out of the plantations remote and harm the environment. Eco-coffee is a greener Alternative. However, its share of the world market is still very low.

Protection for the wild coffee
Coffee is grown all over the world – but ironically, the threatened wild coffee in his homeland of Ethiopia from extinction. He grows in the mountain rain forests of the Kaffa Region and is severely affected by local deforestation. Protection programs attempt to preserve the existence of wild coffee.

Didn’t know that? Coffee was suspected to be “possibly carcinogenic”, and urinary bladder cancer trigger. The International cancer research Agency, IARC, which is affiliated with the world health organization, was come in 1991 to this conclusion.
Who didn’t know so far, it can safely forget again and his coffee. Because after the IARC has reviewed the current research data, again, gives you the all-clear: An increased risk of cancer due to coffee, currently no scientific evidence. The IARC emphasized, however, that classification meant that coffee consumption was safe, but merely that the existing data did not allow conclusions.
Studies, which brought back the coffee with increased bladder cancer, in conjunction, would not have a taken into account, it is called by the IARC: people who drink a lot of coffee, smoked more. Tobacco increases the risk for many types of cancer, and also for bladder cancer. This was purchased at previous studies, the impression is only coffee might cause cancer. In the end, it is once again Smoking.
The experts of the IARC have spotted for your latest report about 500 diet studies in humans and a similar number of animal and laboratory experiments. Their conclusions appear in the journal “Lancet Oncology”.
Coffee lowers cancer risk even
And yet a pleasing news for all the coffee drinkers: The IARC evidence, sees that coffee can protect the consumer even against some types of cancer. Heiner Boeing, head of the European cancer and nutrition study (EPIC) at the German Institute for nutritional research Potsdam-Rehbrücke confirms this: “In the case of breast, stomach and liver cancer we have seen a lower risk with increasing coffee consumption. This relationship was in the case of liver cancer is particularly clear.”
Cancer researchers suggest that the ingredients of coffee to interfere in the hepatic metabolism and protective effect. “According to current epidemiological data, nothing speaks quite clearly against a high coffee consumption. We currently expect rather positive effects.”
Too hot can be dangerous
The all-clear, although there is for the coffee and its ingredients – but a warning: Very hot beverages – whether coffee, tea or water is likely to increase the risk for esophageal cancer alone due to their temperature. This was probably for drinks, which are about 65 degrees Celsius, said the IARC’s chief epidemiologist, Dana Loomis at a press conference.
Mate teas: especially popular in Argentina
“Hot drinks can lead to injuries and damage to the esophagus and thus also the risk of cancer increase,” says Gunter Kuhnle, Associate Professor, Food and Nutritional Sciences, University of Reading. “In particular, Mate is often drunk very hot and continuously. This could affect the risk of cancer.” So it pays to have his tea a few minutes longer to cool.
In 1991, the IARC Mate had been classified as “probably carcinogenic” due to “limited evidence for Carcinogenicity in humans and “sufficient evidence” in animal experiments. Mate-products that are as cold drinks is also popular in Germany, are extracted from the in South America, widespread Matestrauch.
The re-evaluation shows That esophageal cancer accumulate in Parts of South America, goes back to Mate, but the fact that the drink is consumed mostly extremely hot.
Also in other regions of the world where people drink tea very hot, such as in Central and East Asia as well as East Africa, to develop a striking number of human tumors of the esophagus.
The role of the IARC
The International cancer research Agency does not carry out experiments on the carcinogenic hazard of substances. You reviewed only the available literature on experiments conducted by other researchers around the world, from which it draws its conclusions. Then it classifies the substances into categories. These indicate how safe are the data in respect to the cancer hazard of the substance.
Last year, the IARC sausage classified as carcinogenic
In October 2015, the IARC had sausages, bacon and other meat to be classified, products considered to be safe to be carcinogenic. In order for this food ended up together with the smoke in category 1. “This does not mean, however, that the consumption of meat were just as dangerous as Smoking, but only that the data is the same in both cases, a reliable and clearly” emphasized Gunther Kuhnle.
The category says nothing about the hazardousness of the substance, how strong a carcinogen it is. The is often misinterpreted. Smoking is much more dangerous than meat, and certainly more dangerous than hot teas.
