A data set of eating behaviors, mood and sociodemographic features for people following with meat-free or omnivore diet

Exclusion criteria were being outside this age range or following any types of a plant-based diet other than meat free diet (ovo-vegetarian, lacto-vegetarian, lacto-ovo-vegetarian or vegan). A total of 1652 participants responded to the study.

Of these, 86 reported following any other types of plant-based diet, such as a pescetarian diet (eating fish, but no other meat), flexitarian diet (mostly vegetarian, but sometimes includes red meat, fish, or poultry) and they were excluded from the data analysis, leaving 1466 participants, resulting in a response rate of 86%. Of these, 836 self-identified as vegetarian or vegan, and 519 self-identified as an omnivore.
