Understanding the attitudes and perceptions of vegetarian and plant-based diets to shape future health promotion programs.

Vegetarian diets have become a prominent area of interest. However, little research has focused on the attitudes and perceptions on vegetarian diets. The purpose of this scoping review was to methodologically search the literature and summarize public perceptions and attitudes towards a vegetarian diet. Using the information found from this review, the Health Belief Model can be applied to shape future health promotion initiatives to move individuals towards a vegetarian or plant-based diet. The main findings indicate that vegetarian diets are generally perceived in a positive light. There are many barriers to consuming this diet such as health concerns, an unwillingness to make dietary changes, and an enjoyment of eating meat.
