A study has found that high glycemic index foods, like white bread, bagels and rice, increase the risk of lung cancer. The study confirms that carbohydrates¹ are a contributing factor in increasing the risk of the lung disease.

 

研究发现，白面包、百吉饼、米饭等血糖指数偏高的食物，会增加患肺癌的几率。该研究证实，患肺部疾病的人群数量正在增加，而碳水化合物是这种趋势的一个诱因。

 

According to the study, while high glycemic index (GI) foods increase the risk of lung cancer by 49%, low GI foods, like fruits and vegetables were found to lower the risk. The study's lead author Dr Stephanie Melkonian of the University of Texas MD Anderson Cancer Center said: "We observed a 49% increased risk of lung cancer among subjects with the highest daily GI compared to those with the lowest daily GI.

 

"Diets high in glycemic index result in higher levels of blood glucose² and insulin, which promote perturbations in the insulin-like growth factors (IGFs). Previous research suggests increased levels of IGFs are associated with increased lung cancer risk. However, the association between glycemic index and lung cancer risk was unclear."

 

As a part of the study that has been published in the journal Cancer Epidemiology, Biomarkers & Prevention, some 1,905 patients diagnosed with lung cancer were surveyed. Comparisons were made with 2,413 healthy patients. The study's senior author Dr Xifeng Wu said it is the "average quality" and not the quantity of carbohydrates that determines the risk of lung cancer. Non-smokers³ consuming high GI foods, like bagels, white bread, popcorn⁴ and cornflakes, were found to be more at risk compared to smokers.

 

Meanwhile, latest statistics from the Office for National Statistics (ONS) revealed that cancer is on the rise in England, with at least 813 new cases registered every day. The ONS statistics found that breast cancer accounted for the greatest proportion of cancer registrations⁵ in England, making up 15.6% of cancer cases. Prostate cancer followed behind at 13.4% and lung cancer was in the third place making up 12.6% of cancer cases.
