Tomatoes can be okay for IBS, but it depends heavily on the type, quantity, and preparation, as they contain fructans and fructose (FODMAPs) that trigger symptoms like bloating in some people. Small servings of fresh tomatoes (around 1/2 medium or 3 cherry tomatoes) are generally low FODMAP, but larger amounts or processed forms (like paste, sauce, or sun-dried) can become high FODMAP and cause issues, with added garlic/onion in products often being the real culprit. Always test your personal tolerance, as individual reactions vary.
