Glutathione-rich Foods for Type 2 Diabetes

Overview

The purpose of this research study is to find out whether certain plant-based foods may be beneficial for individuals with type 2 diabetes. To meet the goal, study participants will be fed known amounts of foods and nutrients. Before and after participants have eaten the food, they will self-measure height, weight, and waist circumference and study staff will administer questionnaires. Blood samples will be taken at a local lab to measure blood sugar and blood lipids.All study appointments will be conducted online.

This research study is a randomized, controlled trial that will evaluate whether diet and nutrition education on, and short-term partial feeding of, specific plant foods high in the antioxidant glutathione will impact total glutathione status, gamma-glutamyltransferase (GGT) activity, glucose control or insulin sensitivity in people with type 2 diabetes. Dietary education will include information on plant sources of glutathione, as well as, cooking methods to reduce glycation and lipid peroxidation during cooking, which may indirectly alter glutathione status by reduce demand for elimination of these compounds. Participants will be randomized to one of two groups: the educational intervention plus partial feeding of two small meals per day vs. a wait list control group that will receive standard advice on nutrition for diabetes. After 12 weeks, the intervention group will no longer receive foods, but will be followed for 12 additional weeks to determine if lasting effects are achieved. After 12 weeks, the control group will receive access to the educational materials, but will not receive study foods, to see if the educational intervention alone impacts food/nutrition choices. Both groups will have lab measures (as described above) again after this additional 12 weeks, for a total duration of 24 weeks in the trial.
