Cancer survivors need to pay close attention to their diet. Recent research indicates that a diet high in ultra-processed foods significantly increases the risk of death, even after treatment has concluded. Additives, preservatives, and industrial processing methods can trigger inflammation and metabolic imbalances, impacting long-term health.
What foods should people who have had cancer avoid?
The Risks of Ultra-Processed Foods
Ultra-processed foods are industrially manufactured products low in essential nutrients and fiber, but high in sugars, salt, unhealthy fats, and chemical additives. Dr. Marialaura Bonaccio, author of a study published in Cancer Epidemiology, Biomarkers & Prevention, explains that the human body is not equipped to metabolize these artificial substances, and their consumption can disrupt the gut microbiome and increase chronic inflammation.
Even if calorically equivalent to natural foods, the effects on the body are different: metabolism and cardiovascular function are impaired, increasing the risk of complications. This research highlights the importance of dietary choices for long-term health following a cancer diagnosis.
What the Study Revealed
The Italian research followed 802 cancer survivors for 14.6 years, analyzing their dietary patterns. Using the NOVA system, which classifies foods based on their degree of processing, scientists discovered:
- Individuals with the highest consumption of ultra-processed foods had a 48% greater risk of death from any cause.
- The risk of death specifically from cancer increased by 57% in this group.
These negative effects were linked to systemic inflammation and a higher resting heart rate, which accounted for approximately one-third of the additional mortality risk.
Recommendations for Cancer Patients
Researchers emphasize that reducing risks doesn’t indicate eliminating a single product, but adopting a healthy eating pattern. Practical recommendations include:
- Check product labels: If a food contains more than five ingredients, It’s likely ultra-processed.
- Avoid artificial additives and preservatives: Their presence indicates a high degree of industrial processing.
- Choose whole, fresh foods: Fruits, vegetables, whole grains, lean meats, and fish are healthy alternatives.
- Cook at home: Preparing foods naturally reduces exposure to industrial chemicals.
Adopting a diet based on natural, minimally processed ingredients can contribute to extending lifespan and reducing the risks associated with ultra-processed food consumption, offering cancer survivors a chance at better recovery and a higher quality of life.
