Study Details
- Prospective cohort study with 98,459 participants aged 55 and over
- Mean follow-up time of 8.8 years
- Data from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial
Key Findings
- Adherence to a low-fat diet (LFD) associated with reduced risk of lung cancer, especially in smokers
- High consumption of saturated fatty acids linked to increased lung cancer risk, particularly for small cell lung cancer (SCLC)
- No significant association found between monounsaturated or polyunsaturated fatty acids and lung cancer risk
Practical Implications
- Encouraging adherence to a low-fat diet may help in reducing lung cancer risk in middle-aged and older adults
- Avoiding high consumption of saturated fatty acids, especially for smokers, could be beneficial in reducing lung cancer risk
- These findings provide valuable insights for public health strategies and individual dietary choices
