Association Between Health Literacy and Adherence to the Eat- <i>Lancet</i> Sustainable Reference Diet Among Cancer Survivors

This study aimed to investigate whether there is an association between the health literacy of breast and prostate cancer survivors and their feeding, considering the planetary diet recommendation. This cross-sectional study utilized secondary data from 201 women with breast cancer and 106 men with prostate cancer. Health literacy was evaluated using the Brazilian version of the Health Literacy Questionnaire. The EAT-Lancet diet adherence was assessed using the Planetary Health Diet Index (PHDI). The mean PHDI score was 45.3 (9.0) points, without differences in consumption between men and women. The health literacy status and PHDI score were unassociated among cancer survivors. Adherence to a healthy and sustainable diet and health literacy were low among the studied population. Further studies should evaluate these conditions in other populations.
