With ‘1 time per week’ receiving a score of 1, and the remaining responses calculated as a factor of 1. 2 Only habitual intake (and not frequency) of these foods was required for classification of vegan and lacto-ovo vegetarian. Frequency on intake was not provided for butter and butter and margarine blends in the DQES.
