New Year’s resolutions（决心）often fail, but now a new study may just provide motivation for you to stick to them. Scientists found that meeting goals — such as giving up drinking or smoking — can slash your risk of cancer.
The large-scale study — of half a million Britons — looked at the effects of quitting tobacco，limiting alcohol intake, maintaining a low body mass index (BMI), exercising regularly and eating a healthy diet. Each individual behaviour was found to bring a decrease in the chance of getting cancer of about eight per cent. But if people carried out all together the overall risk reduction was about a third — and likely a greater cut in deaths from the disease.
The researchers from Cardiff University examined data from 343,150 people from the UK Biobank to identify the five healthy behaviours and compare them to the risk of cancer. The subjects were aged 40 to 69 and 14,285 were diagnosed （诊断）with the disease during an average follow-up of just over five years. The team found that adopting（采用）all the studied healthy behaviours brought a 25 and 35 percent reduction in bowel and breast cancer respectively — two of the most common forms of the disease.
The team said the findings may not sound surprising — but they serve as a reminder of the importance behind turning resolutions into permanent lifestyle choices.
Professor Elwood, the lead researcher，said the real problem for people adopting resolutions was translating the unclear idea of lifestyle choices being “good” into useful evidence — which was what this study provided. “A healthy lifestyle has many additional benefits to cancer reduction — it costs nothing, has no undesirable side effects…and is better than any pill.”
