Prevention: A brisk 30 minute walk a day can protect against bowel cancer Regular exercise can significantly cut the risk of bowel cancer, research shows. Just 30 minutes of activity a day has been shown to reduce the chance of developing polyps – growths which can become cancerous – by a third. Scientists from Washington University School of Medicine found that people who took regular exercise were 30 per cent less likely to develop the larger polyps most at risk of becoming cancerous.

　　積雪融化、春天又踏著她輕盈的腳步來到了我們身邊，在當今快節奏的繁忙的工作中如何能保持身心健康，“春季將如何養生”又是一個擺在我們面前的重要課題。有來自華盛頓大學醫學院的專家建議，每日30分鐘的有氧慢走可以有效減少患上大腸癌的機率，換句話來說，慢走可以降低胃腸道息肉（胃腸道粘膜局限性增生形成的隆起腫物）的生長速度，具體數字能達到30%，看來，慢走是白領春季養生的最佳選擇之一。

The study, published in the British Journal of Cancer, looked at data from 20 previously published pieces of work. Lead author Dr Kathleen Wolin said: ‘Exercise has many benefits, including boosting the immune system, decreasing inflammation in the bowel and helping to reduce insulin levels.’ Bowel cancer is the third most common form of the disease, and the second most common among women. There are around 38,600 cases a year in the UK. The researchers analysed data from 20 existing studies and found people who lead sedentary lifestyles are more likely to have growths.

　　據悉，這項實驗結果發表在《英國癌癥雜志》期刊上，有專家Dr Kathleen Wolin 說：“鍛煉有許多益處，包括提高自身免疫系統抵御外界侵蝕的能力、降低體內胰島素水平并減少腸道炎癥的機率等等。”據悉，大腸癌是第三大癌癥，而且女性發病的機率會很高。在英國，這種疾病的數量異常龐大，每年共有3萬8千多的類似案例發生，研究人員經過調查證實，有“久坐的不良生活習慣”的人群最容易患上此類疾病。看來，亞健康生活帶來的弊端越來越顯現了，而且城市白領的亞健康趨勢呈上升趨勢，我們要意識到，需要社會關注的問題不僅僅局限于大腸癌而已了。

　　People who took regular exercise were 16 per cent less likely to develop bowel polyps and 30 per cent less likely to develop large or advanced polyps which are more likely to develop into cancer. Professor Wolin said: 'We've long known that an active lifestyle can protect against bowel cancer but this study is the first to look at all the available evidence and show that a reduction in bowel polyps is the most likely explanation for this.

　　有數據顯示，每日能做有規律運動的人比不愿意運動的人患上大腸癌的機率低16%，而胃腸道長息肉的機率也大大減少30%。教授 Wolin 說：“雖然我們都知道有規律的運動可以減少患上大腸癌的機率，但是這次的實驗是首次提供具體數據證實了我們的假想。”
