Sleep is one of the most important and crucial physiological needs for maintaining a healthy life. However, in today's day and age, insomnia and other sleep disorders, such as sleep apnea, are increasing rapidly. This new book details the nutraceuticals from foods that help to promote good health and optimum sleep. The authors discuss the importance of sleep, the role of diet in sleep, the role of specific vitamins and minerals, amino acids and opioids as nutraceuticals for sleep, newer technologies for use and delivery of nutraceuticals for treating insomnia, and more. The book not only explores nutraceuticals that promote optimum sleep but also details foods that cause insomnia, such as processed, chemical-rich, and refined foods. Chapters also cover commensal and symbiotic microbes, microbial metabolites, and bacteriocins and their impact on sleep. A chapter on the ethical issues related to addiction to nutraceuticals for sleep induction is also included.
