A higher adherence to the Chinese Food Pagoda and Dietary Approach to Stop Hypertension diet appears to reduce the risk of premature death and breast cancer-specific recurrence or death among long-term breast cancer survivors

In February 2020 researchers from the USA and China published the results of their study to assess the possible benefits of adherence to dietary recommendations among breast cancer survivors. A total of 3,450 5-year breast cancer survivors in Shanghai were involved in the study. Dietary information was collected via food frequency questionnaires. Adherence scores to the Chinese Food Pagoda-2007, Chinese Food Pagoda-2016, modified Dietary Approaches to Stop Hypertension (DASH), and Healthy Eating Index 2015 diets were then generated. Results showed that those who had the highest adherence scores to the Chinese Food Pagoda-2007, Chinese Food Pagoda-2016 and DASH diets had a 25-34% reduced risk for total mortality and a 36-40% reduced risk of breast cancer-specific events when compared with the lowest adherence scores. The Healthy Eating Index 2015 diet did not appear to be significantly associated with breast cancer outcomes.
