Key clinical point: Women who survive stages I-III breast cancer (BC) may experience improved survival outcomes on adhering to a low-carbohydrate diet, particularly one that is plant-rich.
Major finding: Compared with women having the highest carbohydrate intake, lowest protein intake, and lowest fat intake after BC diagnosis, those adhering to an overall low‐carbohydrate diet (hazard ratio [HR] 0.82; Ptrend = .0001) and a plant‐rich low‐carbohydrate diet (HR 0.73; Ptrend < .0001) had a significantly lower risk for all-cause mortality.
Study details: Findings are from an analysis of two ongoing cohort studies, the Nurses’ Health Study (NHS) and NHS II, including 9621 women with stages I-III BC, of which 1269 women died from BC.
Disclosures: This study was sponsored by the US National Institutes of Health and University of Toronto. Two authors declared being the founder of or receiving personal fees, nonfinancial support, and grants from various sources. The other authors declared no conflicts of interest.
