Want to prevent the breast cancer relapse? Increase your ‘night fast’
Want to prevent a recurrence of breast cancer? Ensure the gap between your dinner and breakfast next day, says a new study.Updated: Apr 01, 2016 14:01 IST
If you are a breast cancer survivor and don’t want a relapse of the deadly disease, then make sure that the time between your dinner and breakfast is long enough. According to a new study, this time, termed ‘night fast’, should be more than 13 hours to lessen the risk of a relapse. The findings showed that a short ‘night fast’ of less than 13 hours led to a 36 percent greater chance of tumours returning in women treated for early-stage breast cancer.
“Our study introduces a novel dietary intervention strategy and indicates that prolonging the length of the nightly fasting interval could be a simple and feasible strategy to reduce breast cancer recurrence,” said lead author Catherine Marinac, doctoral candidate at University of California, San Diego in the US.
Also, going to bed too soon after eating may increase the risk of breast cancer coming back.
A longer nightly fasting interval can significantly lower the concentrations of HbA1c (Glycated hemoglobin) and longer duration of nighttime sleeping.
Interventions to prolong the nightly fasting interval could also potentially reduce the risk of type 2 diabetes, cardiovascular disease and other cancers.
However, shorter fasting was not associated with a higher risk for death from breast cancer or from any other causes.
For the study, published online by JAMA Oncology, the team collected data on 2,413 women with early breast cancer who participated in the Women’s Healthy Eating and Living study, which looked at the effects of diet on women’s health.
Between 1995 and 2007, that is, during an average of 7.3 years of follow-up, the researchers looked at invasive breast cancer recurrence and new primary breast tumors.
Women who participated in the study were of an average age of 52.4 years and kept average fasting duration of 12.5 hours per night.
The findings from this study have broad and significant implications for public health. Randomised trials are needed to adequately test whether prolonging the nightly fasting interval can reduce the risk of chronic disease,” the researchers concluded.
