Summary

A new study links omega-6 fatty acids, common in seed oils used in ultraprocessed foods, to inflammation that may fuel colon cancer.

Researchers found colorectal tumor samples contained high levels of omega-6s and low levels of omega-3s, which help resolve inflammation.

Prolonged inflammation can damage cells, promote uncontrolled cell growth, and increase cancer risk.

Experts suggest the Western diet, heavy in ultraprocessed foods and seed oils, is a likely contributor.

While omega-6s are essential in moderation, their current overconsumption raises concerns, prompting calls for further research and dietary caution.
