An early dinner or an interval of at least two hours before bedtime are both associated with a lower risk of breast and prostate cancer. In particular, people who take their dinner before 21

clock. or wait at least two hours before going to bed have about a 20 percent lower risk of this type of cancer compared to people who dine after 10 in the evening. or those who eat and go to bed with little distance. These were the key conclusions of a new study by the Barcelona Institute for Global Health (ISGlobal), a center supported by the La Caixa Banking Foundation. For the first time, the study analyzes the relationship between cancer risk and the timing of meals and sleep.

Previous studies on the relationship between food and cancer have focused on nutritional patterns – for example, on the effects of red meat, fruits and vegetables, and the links between food intake and obesity. However, other food-related factors received little attention: the time of ingestion and pre- and post-meal activities. Recent experimental studies have shown how important it is to eat the meals and demonstrate the health effects of late eating.

The aim of the new study, which was published in International Journal of Cancer was to assess the meal timing could be associated with the risk of breast and prostate cancer, two of the most common cancers worldwide. Breast and prostate cancer are also among the most associated with night shift work, circadian disorder and alteration of biological rhythms. The study evaluated each participant's lifestyle and chronotype (an individual attribute that correlated with the morning or evening activity preference).

The study included data from 621 cases of prostate cancer and 1,205 cases of breast cancer as well as 872 men and 1,321 women controls randomly selected from primary health care centers. The participants, representing different parts of Spain, were asked about their time of eating, their sleeping habits and their chronotype, and they completed a questionnaire about their eating habits and compliance with cancer prevention recommendations.

"Our study concludes that adhering to daily eating habits entails a lower risk of cancer," stated ISGlobal researcher Manolis Kogevinas, lead author of the study. The findings "emphasize the importance of evaluating circadian rhythms in nutrition and cancer studies," he added.

If the findings are confirmed, Kogevinas said: "They will have an impact on cancer prevention recommendations that currently do not take meals." He added, "Influence could be particularly important in cultures like Southern Europe, where To eat people late at night. "

IS Global Researcher Dora Romaguera, the final author of the study, said, "More human research is needed. To understand the reasons behind these findings, everything seems to indicate that the time of sleep is our ability to feed Animal experimental evidence has shown that the timing of food intake has "profound effects on the metabolism and health of the food".
