Objective : To assess the cost of adopting a plant-based diet.

Methods : Breast cancer survivors randomized to dietary intervention (n=1109) or comparison (n1145) group; baseline and 12-month data on diet and grocery costs.

Results : At baseline, both groups reported similar food costs and dietary intake. At 12 months, only the intervention group changed their diet (vegetable-fruit: 6.3 to 8.9 serv/d.; fiber: 21.6 to 29.8 g/d; fat: 28.2 to 22.3 of E). The intervention change was associated with a significant increase of 1.22/ person/week (multivariate model, P0.027).

Conclusions : A major change to a plant-based diet was associated with a minimal increase in grocery costs.
