Hello, Thank you for your query. I think the combination of grapes, spinach and beans made the IBS worse. If your symptoms resolve in the next day, don t worry. If it doesn t or you develop severe diarrhea with blood or abdominal pain, then see your doctor right away. I recommend ; -Take bland and easily digestible food -have smaller and more frequent meals -chew food well and thoroughly. -avoid too much fiber. Identify trigger foods that worsen symptoms of IBS and avoid them. -cook beans thoroughly to minimize flatulence effect. -add ginger to diet -don t eat fruit or drink milk within an hour of meal times. - avoid too much water along with meals. Sips if required. -don t have cold drinks or sodas along with Meals. If you don t feel better in a day or 2,see your doctor for medication to ease symptoms. Hope this helps. Pls let me know if there is anything else I can help you with. Wish you good health
