High Glycemic Index Diet Linked To Lung Cancer Risk


There is a real need to dissociate the diagnosis of lung cancer from assumptions of cigarette smoking, there do exist quite a fair number of people who have never touched a stick in their life but have been recipients of this terrible diagnosis. A new study carried out at the University of Texas MD Anderson Cancer Center may provide the first hint at evidence between high Glycemic Index (GI) foods or diets and lung cancer risk.

Glycemic Index is a measurement carried out on carbohydrate containing foods and the eventual effect they have on blood sugar. Quite simply; when you eat a carbohydrate based meal, how high and how fast at that does the meal make your blood sugar climb. The study implies that well-known high Glycemic Index foods like white bread, baked potatoes, white rice, corn flakes and so forth, have been ascertained to increase the risk of lung cancer.

High-GI-vs-Low-GI-examplesFor the study, 4,320 people were examined, 1,905 had already been diagnosed recently with lung cancer and 2,415 who had no health issues. Out of the numbers, researchers found a 49% higher risk of lung cancer for people eating food high on the Glycemic Index scale.

The findings were more pronounced among people who had never smoked, those diagnosed with squamous cell carcinoma (a type of lung cancer) and those with less than 12 years of education. The Glycemic Load which can refers to the overall GI intake and is therefore based on the quantity of food consumed, had no significant relationship with lung cancer risk. The researchers therefore suggest that the carbohydrate quality and not its quantity may modulate lung cancer risk.

The study is however far from conclusive as there is no information to give an equivalent food intake and it also did not provide a reliable indication of lifetime dietary patterns and so a lot more evidence is still required but it is sound reasoning to still reduce high intake of high GI foods.
