Dedication To my wife Helen, my daughter Katie, my son Anton, my grandsons Oscar, Arthur and Henry and my granddaughter Aiste who gave me inspiration for writing this book. About the author Dr. Peter Surai started his studies at Kharkov University, Ukraine, where he obtained his PhD and DSc in biochemistry studying effects of antioxidants on poultry. Later he became Professor of Human Physiology. In 1994 he moved to Scotland to continue his antioxidant related research in poultry and in 2000 he was promoted to a full Professor of Nutritional Biochemistry at the Scottish Agricultural College. Recently he was awarded Honorary Professorships in 5 universities in various countries, including UK, Hungary, Bulgaria and Ukraine. In 2010 he was elected to the Russian Academy of Sciences as a foreign member. He has more than 750 research publications, including 150 papers in peer-reviewed journals and 13 books. In 1999 he received the prestigious John Logie Baird Award for Innovation for the development of ‘super-eggs’ and, in 2000, The World’s Poultry Science Association Award for Research in recognition of an outstanding contribution to the development of the poultry industry. In 2017 he became a member of the team at the Moscow State Academy of Veterinary Medicine and Biotechnology named after K.I. Skryabin to conduct a research under a mega- grant of the Government of Russian Federation (Contract No. 14.W03.31.0013). For the last 15 years he has been lecturing all over the world visiting more than 70 countries.
