Bowel cancer is the fourth most common cancer in the UK, and experts believe poor diet is behind half of all cases. 

肠癌是英国第四大最常见的癌症，而专家认为引起一半肠癌病例背后的原因都是不健康的饮食习惯。 

Researchers at Oxford University, funded by Cancer Research UK, looked at data from more than half a million UK women over more than 16 years. It found that those with an extra 300 milligrams of calcium in their diets, equivalent to a large glass of milk a day, had a 17% lower risk of bowel cancer. 

牛津大学研究人员在英国癌症研究基金会的资助下对 50 多万名英国女性在超过 16 年间的医学数据展开了研究。研究发现，每天在饮食中额外摄入 300 毫克钙的人，即等同于每天多喝一大杯牛奶，患肠癌的风险降低了 17%。 

Researchers also said dark, leafy greens, white wholemeal bread and some non-dairy milks, which contain calcium, also had a protective effect. 

研究人员还表示，同样含钙的深色绿叶蔬菜、全麦白面包以及部分种类的非乳制牛奶也具有一定的保护效果。
