I would like to know if you can give me a reliable and comprehensive list of foods, including vegetables and fruits, that will not cause gas and bloating. i looked on line, but the lists all seem to conflict with each other. thank you?

Trial and error: Different people get varying amounts of gassiness with various foods and drinks, because for example different people... have different digesting abilities, eat at different speeds and different quantities, encounter no standard ingredients list for most of the world's foods, take different medications, etc... A list of FODMAPS is at: https://www.ibsdiets.org/fodmap-diet/
