High-GI Carbs Linked To Increased Lung Cancer Risk
A 2025 study links high-glycaemic index (GI) carbs—like white bread, refined grains, and sugary foods—to a 13% higher lung cancer risk. Whole grains, fibre-rich, and plant-based carbs appear protective. While smoking and pollution remain major risks, choosing healthier carbs may support lung health. Quality, not quantity, matters in carbohydrate consumption.
