My fiance is currently trying the vegan diet recommended by Dr Neal Barnard. Its been nearly 2 weeks now. His bloods are coming down and he lost 3lbs in the 1st week. Hurrah! lol. But last night he had chronic heartburn which kept him up for hours. I had made a pasta dish with soya mince and beans in base made of tinned chopped tomatoes. It tasted quite nice but were both wondering if the tomatoes were the cause of his pain. Any ideas ?
