This book is the best that crossed my path for many years. Synthesis Dr. Seignalet Kousmine and it provides clear explanations and synthesis of many food priorities to do and why! I am suffering from an MS for over 12 years and this book allowed me to complete my food still steps (I already ate gluten and cow milk for 12 years) and bring me a huge PLUS ( targeted food supplements). Available and of great humanity, Mr Magnien was there immediately to help me and guide me in my progress. It is my reference. Thank you Mr Magnien
