New research reveals omega-3 and omega-6 fatty acids may significantly reduce cancer risk across multiple types.
Why it matters: This large-scale study of 250,000 participants provides strong evidence for the cancer-fighting potential of these healthy fats. The findings could reshape dietary recommendations and supplement guidelines for cancer prevention.
- Cancer prevention through diet remains a critical public health priority
Key finding: Higher levels of omega-3s and omega-6s were linked to lower rates of up to 19 different cancers, including colon, stomach, lung, brain, and melanoma.
“For women, it’s an easy decision: Eat more omega-3.”
Kaixiong Ye, associate professor at UGA’s Franklin College of Arts and Sciences
The process:
- Tracked over 250,000 UK participants for more than a decade
- Nearly 30,000 developed cancer during the study period
- Benefits remained consistent regardless of BMI, alcohol use, or physical activity
Keep in mind: The study found that high omega-3 levels might slightly increase prostate cancer risk in men, suggesting benefits may vary by gender.
Real-world impact: The findings could encourage increased consumption of fatty fish, nuts, and plant oils.
- The research validates the growing popularity of fish oil supplements while highlighting the need for personalized supplementation strategies.
TL;DR
- Higher omega-3 and omega-6 levels correlate with lower risk across 19 cancer types.
- Benefits appear stronger in women and younger participants.
- While generally protective, effects may vary by gender and cancer type, warranting personalized approaches.
