Cancer survivors who consume a lot of ultraprocessed foods might face greater risks of death, according to a study in Cancer Epidemiology, Biomarkers & Prevention. These foods are often low in essential nutrients and contain additives, artificial flavors, and unhealthy fats. Lead researcher Dr. Marialaura Bonaccio from Italy’s IRCCS Neuromed explained that as ultraprocessed food consumption increases globally, we need to look closer at their effects on health, especially for cancer survivors.
Research suggests that what one eats after a cancer diagnosis can impact survival. However, many studies have primarily focused on nutrition rather than the food’s processing level. Dr. Bonaccio pointed out that ultraprocessed foods can mess with metabolism and gut health, leading to inflammation. Even if these foods seem similar in calories and nutrients to minimally processed items, their overall effect on health can be far worse.
In the Moli-sani Study, researchers followed over 24,000 people from Southern Italy for nearly 15 years, focusing specifically on 802 cancer survivors. They assessed diets using the NOVA classification system, which categorizes foods based on processing. The findings were striking: survivors who ate the most ultraprocessed foods had 48% higher all-cause mortality and a 57% increased risk of dying from cancer compared to those who consumed the least.
Dr. Bonaccio noted that these health risks were not just due to poor nutrition alone but also due to how food is processed. To dive deeper, they looked at biological markers indicating inflammation and heart health. Results showed that inflammation could explain part of the link between ultraprocessed foods and increased mortality.
The study examined various types of ultraprocessed foods, including sugary drinks, processed meats, and snacks. Some groups were linked to higher death rates, while others did not show clear impacts. However, it’s essential to view these foods as part of an overall diet rather than isolated items.
Dr. Bonaccio emphasized that the total consumption of ultraprocessed foods is the key issue. Reducing these foods and favoring fresh, minimally processed items is crucial for better health. Checking food labels for added ingredients can help in making healthier choices.
While this study provides valuable insights, it has limitations. It’s observational, meaning causation can’t be definitively established. Self-reported dietary data can be unreliable, and dietary habits may change over time. The study also faced challenges regarding the number of deaths and lacked details on cancer stages during diagnosis.
As we consider these findings, they underscore the importance of mindful eating, especially for cancer survivors. Moving towards a diet rich in whole foods could greatly contribute to improved outcomes and overall well-being.
