Adherence to planetary health diet and breast cancer risk: insights from a large case-control study in a low-and middle-income country setting.

ABSTRACT:

Background

Breast cancer (BC) is the most frequently diagnosed cancer among women worldwide. Growing evidence highlights the role of overall dietary patterns, rather than individual foods or nutrients, in modulating cancer risk. Among these, the EAT-Lancet diet, developed to promote both human and planetary health, has recently gained attention for its potential in preventing non-communicable diseases. However, its association with BC risk remains understudied, particularly in low-and middle-income countries.

Methods

We conducted a population-based matched case-control study in Morocco, including 2,800 women (1,400 incident BC cases and 1,400 matched controls by age and place of residence). Cases were newly diagnosed, histologically confirmed BC patients recruited from major
