High-GI Carbs Linked to Increased Lung Cancer Risk
A recent study found that eating lots of high-glycaemic index (GI) carbs, like white bread and sugary snacks, might slightly increase the risk of lung cancer.
High-GI foods cause quick spikes in blood sugar, which might lead to inflammation and other changes that could promote cancer.
On the other hand, eating whole grains, fruits, and vegetables might help lower the risk.
Experts say that while smoking and pollution are still the biggest causes of lung cancer, choosing healthier carbs could be a helpful addition to preventing it.
The study doesn't prove that high-GI carbs definitely cause lung cancer, but it suggests that being mindful of the types of carbs you eat could be beneficial.
High-GI carbohydrate diets linked to a 13% higher risk of lung cancer.
Whole grains and fibre-rich foods may reduce lung cancer risk by up to 28%.
High-GI foods cause rapid blood sugar spikes, potentially leading to inflammation and cancer-promoting changes.
Experts recommend choosing whole grains, plant-based carbs, and reducing processed carbs.
Smoking and pollution remain the primary risk factors for lung cancer.
