Note to tea lovers who drink their drink only if thick smoke escapes: it will have to change your habits. As reported by CNN, a study published on Wednesday, 20 March the International Journal of Cancer confirms the link between drinking hot drinks and esophageal cancer. But these researchers from France and Iran went further: they set up the exact temperature from which this risk is present.
After 10 years of tracing 50,000 people in Golestan, a north-eastern state in Iran, they discovered 317 new cases of esophageal cancer. And by measuring the temperature at which the participants regularly drank their tea, they found that eating 700 ml of tea a day at 60 ° C or higher increased the risk of developing this type t 90% cancer. A figure revised downwards, as the World Health Organization (WHO) concluded that this risk was present when drinks reached 65 ° C.
How did they come to such a collection? Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene and Tropical Medicine, quoted by CNN, said, "the heat would cause esophagus lesions and this trauma would lead to cellular changes and so to cancer".
For his part, Dr James Doidge, a researcher at University College London, gives the point: "There is no need to wait for scientists' conclusions to know that repeated itching on any face in the body is increasing. Your risk of cancer The sun gives skin cancer, smoking gives lung cancer, and many foods and drinks contribute to the risk of stomach cancer. gut, "he said, with an irony touch.
Make sure you are all the same, in the US and Europe, tea is rarely eaten at temperatures above 65 ° C (remember, to give you an idea, if necessary, that the water boils to 100 ° C). However, in geographical areas like Russia, Iran, Turkey and South America, there is a common hot drink even hot. The American Cancer Society estimates that 13,750 new cases of esophageal cancer will be diagnosed in men and 3,900 new cases in women in the United States in 2019. Esophageal cancer is the eighth most common cancer in the world and it is often fatal, killing about 400,000 people every year, according to the International Agency for Cancer Research.
