The study was based on data extracted from the American screening trials for lung, colon, and ovary (PLCO), which included more than 101,000 participants aged between 55 and 74 years, according to ‘News Medical’. Ultra-processed foods include processed meats, regular and diet sodas, and manufactured bread, which constitute more than half of the daily diet in Britain.
The study showed that the most consumed types are lunch meats (11%), diet sodas (7%), and caffeine-free sodas (7%). Although researchers considered factors such as smoking and quality, some raised questions about the accuracy of the results.
Professor Sam Hare, a chest radiology specialist at ‘Royal Free London Hospital’, pointed out that the study did not take into account the intensity of smoking, which is the most prominent factor in lung cancer development. Meanwhile, Professor Tom Sanders from ‘King’s College London’ explained that the study lacks a clear explanation of the mechanism through which ultra-processed foods could lead to this type of cancer.
Experts agree on the importance of reducing the consumption of these foods and focusing on healthy dietary choices like whole grains, fruits, and vegetables to help reduce long-term health risks.
