The Kunzhou team used a genetic technique to assess whether coffee increases the risk of cancer and described it as a very effective method.
According to the Australian Broadcasting Corporation, Associate Professor Stuart MacGregor, a member of the research team, said the results of the study were clear.
He said: "the use of genetic techniques to assess whether coffee increases the risk of cancer is a very effective method. And we have shown in this way that drinking coffee does not affect your risk. "
"genes don't lie," he added. "
There was no link between drinking coffee every day and eventually developing cancer, the study found.
The QIMR Berghofer Medical Research Center in Kunzhou analyzed the data of more than 300000 people using the Mendelian Randomization method (Mendelian randomization) and data from previous international observational studies. Data on coffee drinking habits were provided by the participants themselves. Mendelian randomization is a genetic technique that observes the causal response of a target disease by changing the external conditions of genes with known functions. The results have been published in the International Journal of Epidemiology.
In the past, many animal tests have confirmed that coffee contains both carcinogenic substances and antioxidants. The health benefits of coffee have long been the subject of heated debate between the scientific community and the medical community.
Jue-Sheng Ong, the lead researcher in the study, was surprised by the results, pointing out that coffee has always been thought to be a choice between health benefits and an increased risk of cancer, but this is clearly not the case.
The world consumes about 2 billion cups of coffee a day. For coffee, which contains a possible carcinogen, acrylamide, which is also found in fried or baked starchy foods, there have been lawsuits in the United States in the past about whether coffee shops need to write warnings on coffee cups.
QIMR Berghofer researchers think their research may have an impact on public health around the world. However, Associate Professor McGregor believes that government policy does not need to be affected.
At the very least, the findings reassure coffee lovers to drink coffee.
