While fighting against arthritis / osteoarthritis which makes her suffer severely and almost entirely deprives her of the use of her fingers, Jacqueline LagacÔe discovers the hypotoxic diet of Doctor Seignalet. Believing that she has nothing more to lose, she decides to follow him. The results are spectacular. In ten days, the pain was gone and in sixteen months, she completely recovered the use of her fingers. At the same time, she sees significant improvements in the joints of her knees and spine, which had been affected by symptomatic osteoarthritis for several years. It does not take more for this scientist to dive into the reading the increasingly numerous articles which appear, in the Anglo-Saxon world, in particular, on diet in relation to the various chronic inflammatory diseases. Having gathered an abundant documentation, she devotes herself to writing a book "to inform, she writes, those who suffer from chronic pain that changes in their diet could allow them to eliminate their pain and restore their quality of life they no longer believed possible".
