Are your New Year’s resolutions already beginning to slip? New research could provide some much-needed motivation, after discovering that people who stick to lifestyle changes may reduce their risk of cancer by a third.According to a poll conducted by YouGov last month, eating better and exercising more are the top two New Year’s resolutions for Americans in 2018. Other lifestyle changes, including getting more sleep, quitting smoking, and cutting back on alcohol consumption, also make the top 10. Unfortunately, more than 40 percent of us fail such resolutions after just 1 month. But what are the benefits of sticking to them? A new study — recently published in the journal ecancermedicalscience — sheds light. Study leader Prof. Peter Elwood — of the Division of Population Medicine at Cardiff University in the United Kingdom — and colleagues set out to determine how certain healthy behaviors affect the risk of cancer development.
