Coffee consumption does not change the risk of diagnosing or dying from cancer, but has found a new QIMR Berghofer study.

The results of the research are published on the web page International Journal of Epidemiology.

Main author and head of the QIMR Berghofer statistical genetics group, associate professor Stuart MacGregor, said the great Mendelian study of randomization analyzed data from more than 300,000 people and showed that drinking coffee every day did not reduce even It increased the risk of developing any cancer.

"We know coffee is one of the most popular drinks in the world, and they continue to be mixed messages about the role they play in the disease," said Associate Professor MacGregor.

"We also know that the preference for coffee is hereditary.

"Our research in two areas analyzed whether the rates of cancer were different among people with different levels of automatic coffee consumption and if the same tendency was observed when the self-declared consumption was replaced with a genetic predisposition towards coffee consumption .

"We found that there was no real relation between the number of coffee cups that a person had one day and if they developed some type of cancer in particular.

"The study also ruled out a link between coffee intake and the death of the disease."

Coffee contains a complex mixture of bioactive ingredients, including substances such as caffeine and kahweol, which have been shown to have antitumour effects in animal studies.

However, it has not been established its potential anti-cancer effect in humans, up to now, that it has obtained contradictory studies on the general risk of cancer and individual cancers, such as breast and prostate cancer.

The QIMR Berghofer study used cancer data from the Biobanc UK cohort for more than 46,000 people who had been diagnosed with more invasive cancer types, including about 7,000 people who died of the disease.

The genetic and preferential information of people with cancer was compared with data from more than 270,000 people who had never been diagnosed with cancer.

The main researcher at QIMR Berghofer, Jue-Sheng Ong, said the study also analyzed certain common cancers such as breast, ovarian, lung and prostate cancer and that coffee consumption did not increase nor diminished its incidence.

"There were some inconclusive tests on colorectal cancer, where those who reported drinking a lot of coffee had a slightly lower risk of developing cancer, but at the time, examining the data of these people with a Higher genetic predisposition to drinking more coffee seems to indicate a risk of developing the disease, "Mr Ong said.

"The disparity in these findings suggests that more research is needed to clarify whether there is any relationship between colorectal cancer and coffee."

Associate professor MacGregor said the study had implications for public health messaging around the world.

"The health benefits of coffee have been discussed for a long time, but this research shows that changing coffee consumption is not an effective way to protect yourself from cancer," he said.

  • Data from the Australian Office of Statistics on Health Statistics show that in 2011, 46% of the Australian population consumed coffee (including coffee substitutes)
  • According to Food Standards Australia, New Zealand there is no recognized indicative value based on health, such as an acceptable daily intake, for caffeine.
  • In a statement from August 2018, the United States Department of Drugs and Foods said current science indicated that coffee consumption did not pose a significant risk of cancer.
  • The Cohort study of the United States Bank in the United Kingdom is a population-based study of approximately half a million participants in the United Kingdom between 2006 and 2010. QIMR Berghofer's analysis was limited to 438,870 British white participants with adequate genetic consumption and coffee data.
