Subjects were studied using a 3T Siemens Prisma MRI scanner in the morning after a 12-h overnight fast. During the fast, subjects were asked to avoid any alcohol, caffeine, or medication that could affect GI function. Every subject underwent 3 fMRI sessions. Every subject first had a 5-min, eyes-closed, resting-state fMRI scan under a fast state. Then, the subject was instructed to consume a 350g meal consisting of blended natural ingredients (128g firm tofu, 95g pineapple chunks, 57g pineapple juice, 32g blueberry, and 38g banana). Immediately after the meal, every subject had another 5-min, eyes-closed, resting-state fMRI scan under a fed state. About 1-hour post-meal, every subject had another 5-min, eyes-closed, resting-state fMRI scan under a fed state.
