I am certainly not a doctor, but it seemed to me that it was well-known. Look, eg.: https://www.gastroenterologyandhepatology.net/archives/february-2018/health

  "The GFD continues to trend in popular culture and the media, and more people are restricting gluten from their diet. The medical community must seek to provide an evidence-based approach delineating both the benefits and potential harms of a GFD. Although convincing evidence is available to support the benefits of a GFD for certain patient populations without a gluten-related disease (especially patients with IBS and NCGS), the data are conflicting and not definitive. It appears that most individuals who participate in a GFD do not have a physiologic requirement for the diet and likely do not derive substantial benefit. Existing evidence for potential harms of a GFD include possible nutritional deficiencies, financial costs, and negative psychosocial implications. As with other dietary interventions, a GFD is a rapidly evolving topic, and additional insight is needed to guide a complete discussion between patients considering a GFD and their health care providers."
