A recent study published in the journal Thorax has found a concerning link between the consumption of ultra-processed foods (UPF) and an increased risk of lung cancer. This research sheds light on the potential impact of diet on the development of this deadly disease, which is the most common cancer worldwide.
The study, which analyzed data from the US Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trials, included over 100,000 participants who completed a Food Frequency questionnaire on their dietary habits. The researchers focused on UPF, which are heavily processed foods containing additives and preservatives, such as sour cream, ice cream, fried foods, and sugary drinks.
Over a 12-year tracking period, the study found that individuals with the highest intake of UPF were 41% more likely to be diagnosed with lung cancer compared to those with the lowest intake. This association was particularly strong for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).
While this study is observational and cannot establish causation, the researchers highlight the concerning nutritional profile of UPF, which are often high in sugar, salt, and unhealthy fats. They suggest that the rise in UPF consumption globally may be contributing to the increasing rates of obesity, cardiovascular disease, and cancer.
The researchers emphasize the importance of further research to confirm these findings in different populations and settings. If a causal relationship is established, reducing the consumption of UPF could potentially help lower the burden of lung cancer worldwide.
This study underscores the importance of a healthy diet rich in whole grains, fruits, and vegetables in reducing the risk of cancer. By limiting the intake of processed and ultra-processed foods, individuals may be able to protect themselves against this deadly disease. More research is needed to fully understand the impact of diet on lung cancer risk, but these findings provide valuable insights into the potential role of nutrition in preventing this devastating illness.
