What is SugarScience? is designed as an authoritative source for the scientific evidence about sugar and its impact on health. Developed by a team of health scientists from the University of California, San Francisco (UCSF), the site reflects an exhaustive review of more than 8,000 scientific papers that have been published to date, with a focus on the areas where the science is strongest – specifically, on diabetes, heart disease and liver disease. The goal of SugarScience is to take this information out of medical journals and make it available to the public, to help individuals and communities make healthy choices.

SugarScience enables you to:

  • Explore the latest, evidence-based research on the health effects of sugar overconsumption;
  • Ask the SugarScientists questions to clear up confusion or learn more about sugar's impact on our health;
  • Download flyers, posters or graphics from the SugarScience Resource Kit to post on your refrigerator, share with friends or family, or use in presentations to your community and schools;
  • Stay connected through our newsletter, SugarScience Alerts, featuring new science and expert perspectives, and follow us on social media.
