People considered genetically more likely to drink coffee are nearly three times more likely to develop esophageal cancer.
Researchers say that drinking hot coffee may increase the risk of esophageal cancer. It is assumed that this is due to the fact that hot liquids harm the tissues of the organ. The Daily Mail writes about it.
It has been noted that people who are genetically predisposed to drinking coffee may have an increased risk of developing esophageal cancer, but not other types of cancer.
Experts from the University of Cambridge compared the genes of more than 360,000 people in the UK and Finland and linked them to the risk of developing 22 types of cancer over 11 years.
They did this to account for the same factors that may have slowed previous studies. For example, those who admitted to drinking coffee also tended to drink more alcohol, which may explain their higher risk of cancer.
But the genes associated with a love of coffee are not necessarily related to lifestyle factors such as smoking or drinking. That’s why Dr. Steve Burgess and his team that studying the volunteers’ DNA makes it easier to determine whether coffee causes cancer.
The data showed that people thought to be genetically more likely to drink coffee were nearly three times more likely to develop esophageal cancer. No such association was found for any other type of cancer.
“The good news is that drinking coffee does not increase your chances of developing most cancers,” says Dr. Burgess.
Having coffee-loving genes increases the risk in heavy coffee drinkers, as well as in people who prefer other hot beverages. This suggests that the effects may be due to tissue damage caused by the hot liquid rather than the coffee itself.
“The most likely reason for the association between drinking coffee and esophageal cancer is that pouring hot liquid down the throat causes some damage,” added Dr. Burgess.
This idea is supported by a previous study from 2019, which found that drinking tea at temperatures above 60°C increases the risk of esophageal cancer. Scientists believe that when hot drinks burn cells in this organ, it causes inflammation, which damages genes and causes cancer. But more evidence is needed to confirm the results.
Although the WHO concluded five years ago that it is safe when consumed at normal serving temperatures, ie 65°C or below.
It is worth noting that caffeine is considered safe to consume in doses up to 400 mg per day for the general population. It also has many health benefits, including fighting liver disease and type 2 diabetes. The world’s most widely used stimulant has been proven to increase daily energy expenditure by approximately five percent.
Researchers say that the combination of two to four cups of coffee a day with regular exercise will be more effective for weight loss.
Remember, earlier, scientists from the California University of Public Health in San Francisco called a sudden signal that could indicate the development of leukemia.
