Is Omega-6 in Seed Oils Fueling the Rise in Colon Cancer?

Colon and rectal cancer are on the rise, especially among younger people. Scientists are scrambling to understand why. A recent study published in the journal Gut points a finger at ultra-processed foods, suggesting they may contribute to tumor growth by fueling inflammation.




The Omega-6 Connection:

This study uncovered an intriguing detail: cancer tumors from patients showed high levels of omega-6 fats and low levels of omega-3 fats. This imbalance is concerning because:

Omega-6s: These fats, abundant in many seed oils, can promote inflammation when consumed in excess.

Omega-3s: These fats, found in fatty fish, chia seeds and flaxseeds, have anti-inflammatory properties.

The Role of Ultra-Processed Foods:

Ultra-processed foods, often packed with seed oils, are a major source of omega-6s in the modern diet. The study suggests that excessive consumption of these foods may disrupt the delicate balance of omega-6s and omega-3s in the body. This imbalance can create a pro-inflammatory environment that allows tumors to thrive.

Does this mean seed oils cause cancer?

Not necessarily. Omega-6 fats are essential for the body in moderation. However, a diet heavily skewed towards omega-6s at the expense of omega-3s can create a chronic inflammatory state, increasing the risk of various health problems, including cancer.

The Bigger Picture:

It's important to remember that the study points to the broader issue of ultra-processed food consumption. These foods, often laden with seed oils, may contribute to cancer risk by:

  • Fueling inflammation: Creating an environment where tumors can flourish.
  • Weakening the immune system: Making it harder for the body to fight off disease.

What can you do?

  • Limit ultra-processed foods: Choose whole, unprocessed foods whenever possible.
  • Increase omega-3 intake: Include fatty fish like salmon, mackerel, and sardines in your diet. repalce seed oil with avocado and olive oil. Incorporate chia seeds and flax seeds. 
  • Consider omega-3 supplements: If you don't eat enough fish, talk to your doctor about supplementation.
