In recent years, plant based diets have gained popularity and the supporting evidence has caught the attention of many health professionals. Many health organizations, including the Academy of Nutrition and Dietetics (AND), the American Institute of Cancer Research (AICR), and the World Health Organization (WHO) have put out statements recommending some version of the diet. Plant based diets have been found to be a positive tool in fighting cardiovascular disease, some types of cancers, and obesity. As the nutrition experts, it is the Registered Dietitian Nutritionist's (RD/RDN) job to study, learn, and educate patients and other professionals about all research that may increase positive health outcomes. A quantitative study surveying RD/RDN in the state of Missouri was designed to evaluate their perception on the plant based diet. Demographics were analyzed using descriptive statistics and Chi-square analysis was used to examine relationships between various demographic statistics and the RD/RDN's perception on the diet. The results indicate that RD/RDN in Missouri disagree they would hesitate to recommend a plant based diet based on perception that the diet is not beneficial on promoting overall health. Results were not statistically significant in relationship to years in practice, reading of AND's white paper over vegetarian diets, and years of training.
