With diets we don't see the effects fully in the short term and from what you said I highly suggest you work out how to eat a range of vegetables in your diet, to support your nutritional long term needs.
If it's not just fruit but also vegetables that trigger your digestive issues, are you aware of the low Fodmap diet? It is based around understanding which vegetables don't cause the inflammation you mentioned, designed for people with digestive issues and reducing food irritation and inflammation.
