Certain foods high in omega-6 fatty acids may hinder the body’s ability to combat colon cancer cells, according to a new study. Excessive omega-6, commonly found in ultraprocessed foods, could disrupt the anti-inflammatory and tumor-fighting properties of omega-3 fatty acids. This imbalance may create a pro-inflammatory environment conducive to cancer growth.
Omega-3s, found in fatty fish like salmon, mackerel, and sardines, as well as in flaxseeds, walnuts, and chia seeds, support immune defense and reduce inflammation. Conversely, omega-6s, present in seed oils used in many processed foods, can promote inflammation if consumed in excess.
The study revealed that tumor tissues from colorectal cancer patients contained higher levels of pro-inflammatory omega-6 molecules compared to healthy tissues, which maintained a balance of omega-3 and omega-6. Experts suggest boosting dietary omega-3s to counteract the effects of excess omega-6.
Omega-3 EPA and DHA are found in fatty fish.
Eating two servings of fatty fish per week, incorporating seeds and nuts into meals, or considering fish oil supplements can help restore this balance. However, consult a doctor before starting supplements to ensure they suit your health needs.
