People who have an early supper or go to sleep at least two hours after having dinner have a 20% lower risk of breast and prostate cancer than people who go to sleep immediately after eating. This is the main conclusion of work conducted by ISGlobal, in the first analysis of the link between cancer risk and the timing of meals and sleep, which has been published in the International Journal of Cancer. The study, which was part of theMCC-Spain project and was co-financed by CIBERESP, included data from 621 cases of prostate cancer and 1,205 cases of breast cancer, as well as 872 male and 1,321 female controls. The participants, from various parts of Spain, were interviewed about their meal timing, sleep habits and chronotype, in other words, their preference for morning or evening activity, and completed a questionnaire on their eating habits as well as their adherence tocancer prevention recommendations.
“Our study concludes that sticking to diurnal eating patterns is associated with a lowerrisk of cancer”, explains Manolis Kogevinas, lead author of the study. The findings “highlight the importance of assessing circadian rhythms in studies on diet and cancer”, he points out. - Carlos Sierra / PRBB
