研究称高碳水化合物饮食或增大肺癌风险

      据外媒报道，一项最新研究发现，包括白面包、米饭等高碳水化合物可能会增加肺癌风险。这些食物的血糖生成指数（GI）较高。

    血糖生成指数（GI）是衡量碳水化合物质量的指标，依据饭后血糖升高水平来定义。目前理论是高GI饮食会提高血糖和胰岛素浓度，而体内称为类胰岛素生长因子（IGF）的荷尔蒙也随着升高。

    研究人员梅尔科尼恩（Stephanie Melkonian）称，与每日饮食最低GI的人相较，每日最高GI饮食的人，患肺癌风险增加49%。

    Many studies suggest carbohydrates are bad for your waistline.

    But a new study has warned they may also be bad for your lungs.

    Specifically, foods with a high glycemic index - such as white bread or bagels, corn flakes and puffed rice - may increase the risk of lung cancer, scientists say.

    And non-smokers, who account for 12 per cent of those killed by the disease, appear to be particularly at risk.
