A recent study suggests that consuming high amounts of ultra-processed foods (UPFs) may be linked to an increased risk of lung cancer, with some estimates indicating up to a 41% higher risk compared to diets low in UPFs.

Key Findings:

• Higher UPF intake was associated with a 41% increased risk of lung cancer, even after adjusting for smoking and other risk factors.
• Possible mechanisms include additives, acrylamide (from processed carbs), and inflammatory effects of UPFs.
• Other cancers (e.g., colorectal, breast) have also been linked to UPF consumption in previous studies.

What Are Ultra-Processed Foods?

UPFs are industrially manufactured products with additives, preservatives, and artificial ingredients, such as:

• Packaged snacks (chips, cookies)
• Sugary cereals
• Fast food
• Sodas & processed meats

Recommendations:

• Limit UPFs and opt for whole, minimally processed foods (fruits, vegetables, whole grains, lean proteins).
• Read labels—avoid products with long ingredient lists full of unrecognizable additives.

While more research is needed, this study adds to growing evidence that diet quality plays a role in cancer risk.
