Fizzy drinks increase risk of pancreatic cancer
The high consumption of sweetened food and drink increases the risk of developing pancreatic cancer, according to a new study from Karolinska Institutet. A heavy intake of fizzy drinks, creamed fruit and sugar in coffee are three common ways of increasing the risk.
Pancreatic cancer is a very serious form of cancer that is possibly caused when the pancreas produces heightened levels of insulin as a consequence of upset glucose metabolism. A well-known way of increasing insulin production is to eat a lot of sugar. Scientists have now, for the first time, shown that the consumption of sweetened food and drink affects a person's chances of developing pancreatic cancer.
The study began in 1997 when scientists ran a dietary survey of almost 80,000 healthy women and men. This group was subsequently monitored until June 2005. According to the cancer registry, 131 people from this group had developed cancer of the pancreas.
The researchers have now been able to show that the risk of developing pancreatic cancer is related to the amount of sugar in the diet. Most at risk were those who drank high quantities of fizzy or syrup based (squash) drinks. The group who said that they drank such products twice a day or more ran a 90% higher risk than those who never drank them. People who added sugar to food or drinks (e.g. coffee) at least five times a day ran a 70% greater risk than those who did not. People who ate creamed fruit (a product resembling runny jam) at least once a day also ran a higher risk ?they developed the disease 50% more often than those who never ate creamed fruit.
"Despite the fact that the chances of developing pancreatic cancer are relatively small, it's important to learn more about the risk factors behind the disease," says Susanna Larsson, one of the researchers involved in the study.
"It is perhaps the most serious form of cancer, with very poor prognoses for its victims. Since it's difficult to treat and is often discovered too late, it's particularly important that we learn to prevent it," she says. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 富有泡沫的饮料会增加患胰腺癌风险
Karolinska Institutet一项新的研究报道，甜味食品和饲料的大量消耗增加了患胰腺癌的危险。大量食用发泡饮料、奶油水果和咖啡加糖是增加这种危险的三种最常见的方式。
由于葡萄糖代谢紊乱，胰腺产生更高水平的胰岛素，胰腺癌是可能由此导致的非常严重的一种癌症。众所周知的增加胰岛素分泌的办法就是吃很多糖。科学家们现在首次表示，食用加糖的食物和饲料影响了人患胰腺癌的机率。
这项研究在1997年开始，科学家们调查了80,000个健康的男性和女性的饮食，并一直监测到了2005年6月。根据癌症的登记情况，这组人群中有131个人患了胰腺癌。
研究者们现在能够说患胰腺癌与食物中的糖分有关。最危险的是那些饮用大量发泡或含糖浆饮料的人。这组人群中，那些每天饮用2次或更多此类饮料的人比那些从不饮用此类饮料的人高出90%的危险。每天至少5次在食物或饮料（咖啡）中加糖的人比那些从不加糖的高出70%的风险。每天至少一次吃奶油水果（类似松软果酱的食品）的人也有着更高的发病危险。他们患胰腺癌的危险比那些从不吃奶油水果的人高出50%。
“虽然患胰腺癌的机率很小，知道此病的危险因素是非常重要的”，Susanna Larsson说，她是本研究的研究者之一。
“这可能是最严重的一种癌，预后非常差。由于它很难治疗，发现又晚，学会预防尤其重要。”她说。
