A simple meal plan of 'eating vegetables before carbohydrate ' was more effective for achieving glycemic control than an exchange-based meal plan in Japanese patients with type 2 diabetes . This study aimed to determine whether educating diabetic patients to 'eat vegetables before carbohydrate ' was as effective on long-term glycemic control as a traditional exchange-based meal plan . To test this hypothesis , we carried out a randomized , controlled trial in patients with type 2 diabetes that compared changes in HbA1c as the primary outcome . A total of 101 patients were stratified according to sex , age , BMI , duration of diabetes , and HbA1c , and then randomized to receive instructions to eat either vegetables before carbohydrate ( VBC , n=69 ) or an exchange-based meal plan ( EXB , n=32 ) . The impact of the two plans on glycemic control was compared over 24 months of follow-up . Significant improvements in HbA1c over 24 months were observed in both groups ( VBC , 8.3 to 6.8 % vs EXB , 8.2 to 7.3 % ) . HbA1c levels were significantly lower in the VBC group than in the EXB group after 6 , 9 , 12 and 24 months of the study . Both groups exhibited similar improvements in dietary practices with respect to intake of carbohydrate , fats and sweets , while the VBC group had a significant increase in consumption of green vegetables and a significant decrease in fruit consumption . A simple meal plan of 'eating vegetables before carbohydrate ' achieved better glycemic control than an exchange-based meal plan in Japanese patients with type 2 diabetes over a 24-month period .
