Our Values


Data-driven science always serves as the base of the information the PCSI provides. We do understand that food and food ingredient choices are very personal, but our mission is based on science-based information sharing.


Being transparent in all our efforts is of the upmost importance for maintaining trust in our food supply more broadly, and in stevia more specifically. To do so, we communicate in an open and honest way with all of our audiences from partners to consumers.


To further enhance awareness and education of stevia, the PCSI partners with companies and organizations throughout the world to support stevia education efforts.To see the latest news and information from the PCSI, visit our News page.
