by Academics have found a connection between the consumption of high ultra -processed food (UPFS) and lung cancer.
An international team of researchers pursued the health and food habits of more than 100,000 US -growing people with an average age of 63 years.
After an average of 12 years, the team identified 1,706 cases of lung cancer.
And questionnaires for food survey revealed the consumption of UPFS, including ice cream, fried food, bread, cake, pastries, salty snacks, breakfast flakes, immediate pasta and soups, margarine, sweets, non -alcoholic drinks, sweetened fruit drinks, hamburgers, hot dogs and pizza.
The research team listed by academics in China found that the average UPF consumption was almost three portions per day, but was between 0.5 and six.
The three types of dishes with the most were lunch and soft drinks.
People who consumed the highest amounts of UPFS developed 41% more likely to develop lung cancer than those who consumed the slightest amount, wrote in the THORAX magazine.

They found an increased risk of lung cancer without small cells and lung cancer with a small cell.
The authors said that they were adapting their results based on whether people smoked or not, but they did not make any adjustments to the smoke intensity, which may have affected.
They emphasize that “causality cannot be determined” from their results and the data should be interpreted with caution.
“Although additional studies are justified in other population groups and environments, these results indicate the healthy advantages of limiting the UPF,” said the authors.
They added: “Referring trends of the UPF recording worldwide could help reduce the stress of lung cancer.”
Professor Sam Hare, advisor to the Royal Free London NHS breast -lime, said to the study: “A quarter of lung cancer cases occur in non -smokers, so we have to examine whether other factors are connected to lung cancer.
“We also know that immunity is associated with cancer biology, so it is a good idea to research factors such as nutrition.
“However, further work is required to determine a direct cause between UPFS and lung cancer. It is crucial, while the study makes some adjustments to smoking status. The amount of smoking is not taken into account, which is known to be directly connected to the development of lung cancer.
“Even in the course of such long-term studies, eating habits change considerably, as such that lung cancer is only related to the level of UPF consumption, since it was only explained at the beginning of the study.
“In view of the relative lack of information on non -smoking risk factors in lung cancer, it is important that the scientific community carries out more such studies. We need real evidence -based progress in the early diagnosis of lung cancer in non -smokers, but this study is not yet able to give us the answers.”

In a separate study, the smoking rates of teenagers over 50 years were examined in Great Britain.
Researchers under the direction of academics of the University of Michigan in the USA examined the data for smoking 16 and 17 year olds in 1974, 1986 and 2018.
They found that smoking teenagers decreased from 33% to 12% during the investigation period.
The 2018 study showed that 11% of older teenagers used Vapes.
The authors of the study estimate that teenagers who are Vape vape are rather smokers.
In the Tobacco Control magazine, they said that the likelihood of smoking among teenagers who were not vape, was 1.5%, but with those who do so.
“The efforts to control tobacco should continue to concentrate on the prevention of the nicotine use of general young people and especially address young people who use e-cigarettes because their risk of smoking cigarettes in the 1970s is similar,” they wrote.
But academic commentators said that this conclusion is “not justified”.
