Fad diets past and present, including taurine for psoriasis, diet therapy for atopic dermatitis, and the role of elimination diets.

The effect of diets and foods on cutaneous afflictions has never been a moot point. The number of inquiries from patients and the wider public about how certain foods have affected or, indeed, caused their skin eruption, is increasing. While this inquisition is at the forefront of people's and physicians' minds in modern practice, this has long been a discussion in the scientific world. Élie Metchnikoff alluded to this at the turn of the 20th century. How foods and certain dietary programs affect diseases has been postulated, although there is still more to learn, despite the patient's advocacy for a particular dietary regimen. The study of the role of the microbiome is increasing. Gut dysbiosis, along with the interaction of the gastrointestinal tract, skin, and brain (gut-skin-brain axis) is discussed. The role and impact of neuroendocrine transmitters and the skin are explored. [ABSTRACT FROM AUTHOR]
