Scientists have found an association between late diners and the development of breast and prostate cancer. In general, it is recommended avoid dinner after 21 hours.
In a new study published in the International Journal of Cancer, scientists have found an association between late diners and the development of breast and prostate cancer. “Compared with people who slept immediately after dinner, those who slept for two hours or more after dinner had a 20% reduction in the risk of breast and prostate cancer,” the study said. The risk of developing breast cancer decreased by 16% and that of developing prostate cancer by 26%.
In addition, a similar protection was observed in the subjects who had dinner before 9 pm compared to those who dined after 10 pm. The effect of lengthening the dinner-sleep interval was more pronounced in the subjects who followed the recommendations in terms of cancer prevention (balanced diet, non-consumption of alcohol and tobacco, etc.). Respect for eating habits and a long interval between the last meal and sleep are also associated with a lower overall risk of cancer.
Medical records of 621 prostate cancer patients and 1,205 breast cancer patients were analyzed and compared to a healthy group of 1,321 women and 872 men. “The hypothesis we tested is supported by experimental evidence and emphasizes the importance of assessing circadian rhythms in studies of diet and cancer,” the scientists said. For them, cancers are often associated with the evolution of hormones, which themselves depend on the circadian rhythms of the body.
“We know that the body makes digestive enzymes that will react differently depending on what you eat and the time you eat.” The findings of the researchers are not surprising, “says French nutritionist dietitian Hélène Brunengo. Chrono-nutrition, a field explored since the 1950s, consists of eating according to the biological rhythms of your body. “We should avoid eating after 9 PM (except for night workers obviously). The intestinal movements stop from 10:30 pm. If we eat a lot and late, we will feel digestive discomfort and body temperature will increase. This will hurt sleep,” adds the professional.
According to another study, published last year, eating late in an 8-week period would increase the risk of diabetes, obesity, atherosclerosis and other cardiovascular problems.
