據外媒報道，一項最新研究發現，包括白面包、米飯等高碳水化合物可能會增加肺癌風險。這些食物的血糖生成指數（GI）較高。
血糖生成指數（GI）是衡量碳水化合物質量的指標，依據飯后血糖升高水平來定義。目前理論是高GI飲食會提高血糖和胰島素濃度，而體內稱為類胰島素生長因子（IGF）的荷爾蒙也隨著升高。
研究人員梅爾科尼恩（Stephanie Melkonian）稱，與每日飲食最低GI的人相較，每日最高GI飲食的人，患肺癌風險增加49%。
部分原文報道如下：
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.
