As a retail dietitian, you suggest food options and provide dietary information to customers in retail stores. Some details of this job depend on the type of store at which you work. At supplement-focused stores, you may provide pills designed to help treat various conditions. At organic food stores, you may help customers plan healthy, minimally-processed meals. While part of your responsibilities is to increase sales, being a retail dietitian also requires providing good advice to people based on their nutritional needs. Balancing these responsibilities is essential to success as a retail dietitian.
