Beyond Smoking: Your Diet's Role in Lung Cancer
1 Dec
Summary
- High-glycaemic index carb diets linked to 13% higher lung cancer risk.
- Refined carbs spike blood sugar, potentially fueling cancer growth.
- Whole grains and plant-based foods may offer protective benefits.
Emerging research in 2025 highlights a significant association between diet and lung cancer, moving beyond traditional risk factors like smoking and pollution. A recent study indicates that consuming high-glycaemic index (GI) carbohydrates, which cause rapid blood sugar spikes, is linked to a 13% increase in lung cancer risk. This includes common foods like white bread, refined grains, and sugary snacks.
Scientists suggest that these dietary patterns can lead to chronic inflammation and elevated growth factors, potentially promoting abnormal cell growth. Conversely, diets rich in whole grains, fiber, fruits, and vegetables appear to stabilize blood sugar and reduce inflammation, offering a protective effect. Experts advise prioritizing whole grains and plant-based foods over refined carbohydrates.
While this dietary link is notable, it is crucial to remember that smoking and air pollution remain the dominant drivers of lung cancer. The study's findings underscore the importance of a balanced, conscious approach to carbohydrate consumption as a complementary strategy for lung health. Further research is needed, especially among diverse populations, to solidify these conclusions.
