A new study published in the scientific journal Thorax revealed that the consumption of ultra-processed foods, such as soft drinks, snacks and ready-to-eat meals, is associated with a significant increase in the risk of developing lung cancer. The research, which analyzed data from more than 100,000 participants in the Estados Unidos, followed cancer diagnoses and deaths over several years, highlighting concerns about current eating habits.
Although the research is observational and does not establish direct causality, scientists point out that factors such as industrial processing and the presence of harmful substances, such as acrolein, may contribute to the observed risks. The investigation also raises questions about the role of packaging and chemical additives in human health.
Among the main ultra-processed foods analyzed, processed meats, soft drinks with and without caffeine, and snacks stood out. The study recorded 1,706 new cases of lung cancer over a 12-year period, with a higher incidence among frequent consumers of ultra-processed products.
The researchers suggest that adopting a diet focused on fresh and minimally processed foods can be an effective strategy to mitigate the health risks associated with consuming these products, reinforcing the importance of conscious food choices.
Discoveries about the food link and disease risk
The American study, which examined information from 101,732 participants aged between 55 and 74, identified a notable correlation between the intake of ultra-processed foods and the development of lung cancer. Durante follow-up, 1,473 cases of non-small cell lung cancer (NSCLC) and 233 cases of small cell lung cancer (SCLC) were diagnosed.
After adjusting the data for other risk factors, including smoking and general diet quality, individuals who consumed the most ultra-processed foods were 41% more likely to develop lung cancer. Essa elevation was observed for both the NSCLC subtype, with a 37% higher risk, and SCLC, with a 44% higher risk.
Problematic components of industrialized products
Ultra-processed foods, which include items such as fast food burgers, pre-made pizzas and various breakfast cereals, are defined by their extensive ingredient lists. Essas lists often contain additives, preservatives and flavors that are not found in homemade culinary preparations.
These products go through multiple stages of industrial processing, which profoundly modifies their original food matrix. Este process results in the reduction of essential nutrients and, at the same time, increases the presence of compounds that can be harmful to health in the long term.
Substances such as acrolein, which appears in grilled sausages and caramelized sweets, are examples of problematic compounds. Curiosamente, acrolein is also found in cigarette smoke, indicating a possible route of exposure to harmful agents through the diet.
Most common food items in the analysis
Among the most predominant ultra-processed foods in the diet of study participants, processed meats, such as sausages and sausages, represented a significant portion. Esses items made up around 11% of the total consumption of ultra-processed foods, indicating their strong presence in eating habits.
Soft drinks, both those with caffeine and those without caffeine, were also among the most consumed products, accounting for 7.1% and 6.9% of consumption, respectively. The list of frequent items also included snacks, processed breads, ice cream and a variety of ready-made sauces, all easily accessible in supermarkets and fast food establishments, which facilitates their inclusion in the daily eating routine.
Global scenario of lung cancer incidence
Lung cancer remains one of the leading causes of cancer mortality on a global scale. Segundo updated data, around 2.2 million new cases and 1.8 million deaths were recorded in a recent year, underlining the severity and scope of the public health problem. Although smoking is recognized as the main risk factor for this disease, current research suggests that diet, especially high consumption of ultra-processed foods, may play an increasingly important role in increasing incidence. In nations like the Estados Unidos and the Reino Unido, where more than half of the daily diet is made up of these products, the challenges of controlling the disease intensify. The implementation of public policies that encourage access and consumption of fresh food, along with raising awareness about the dangers of ultra-processed foods, emerges as a crucial strategy to reverse projections and mitigate the global impact of the disease.
Recommendations for healthier eating
Nutrition and public health experts recommend adopting small but consistent changes in eating habits to reduce dependence on ultra-processed foods. Cozinhar at home, using fresh, minimally processed ingredients, is one of the most effective strategies for reducing exposure to additives and preservatives.
Another important practice is to plan your meals in advance, which helps to avoid impulsive choices for processed foods. Carefully reading product labels is essential to identify the presence of undesirable ingredients and choose more nutritious alternatives.
Including a wider variety of whole foods, such as fruits, vegetables, legumes and whole grains, in your daily diet can significantly improve nutritional quality. Essas choices provide essential fiber, vitamins and minerals that contribute to overall health and can help prevent disease.
Simple substitutions, such as swapping soft drinks for water, natural teas or fruit juices without added sugar, represent an important step. Campanhas Food education and tax incentives for fresh foods can also play a crucial role in making healthier options accessible to all segments of the population.
Notes and future investigations
Despite the relevance of the results presented, it is important to recognize that the study, due to its observational nature, does not establish a direct cause and effect relationship. Além Furthermore, collecting dietary data at a single point in time does not reflect possible changes in participants’ eating habits over the follow-up period. Pesquisas Futures should deepen understanding of how specific chemical compounds present in ultra-processed foods interact with the body and explore the effectiveness of regulatory policies in reducing health risks.
