▪ Content : Background and Objectives: Our aim was to evaluate the effect of consuming tomato juice before carbohy-drate on postprandial glucose concentrations in healthy women. Methods and Study Design: In this random-ized controlled cross-over study, 25 healthy women (age 21.6±3.8 years, HbA1c 5.3±0.2 %, mean±SD) con-sumed either 200 g of tomato juice, tomato, or water (control) at 30 min before consuming 200 g of boiled white rice at 9:00 and consumed identical lunch at 13:00 for 3 days. The blood glucose concentrations were measured by self-monitoring blood glucose at 0, 30, 45, 60, 90, 150, and 210 min pre- and post-breakfast, and at 0, 30, 60, 120, 150, and 180 min pre- and post-lunch.
