Among Earth's most nutrient-dense foods, microalgae are sold worldwide. Understanding microalgae has powerful implications for our health and for our planet. Jeffrey Bruno, Ph.D. has created a comprehensive, well researched book (with over 900 citations). Eat Light & Feel Bright is solid evidence-based book, backed by clearly explained scientific studies. He brings to light how these transformational microscopic organisms can help rebuild our health and restore our environment. Eat Light & Feel Bright offers more than the most comprehensive and far-reaching research collection on microalgae. This book delivers a transformational journey on human health and nutrition, using microalgae as a way to gain a deeper understanding of the evolutionary basis of nutrition. Part I describes how microalgae helped to change our world and provide foundational nutrients, like amino acids and bioactive light-sensitive pigments. The reader will learn about heat-shock proteins and how blood heme and algae pigments share common qualities. Part II describes 12 areas of microalgae health research from anti-inflammatory and antioxidant effects to safety concerns. Part III highlights the use of microalgae for planetary medicine, helping to address global hunger and ecological restoration. The future of microalgae as a sustainable energy source and microalgae solutions to tackle rising CO2 levels is presented. An accessible book for most readers - based on sound science over 910 references - describes how microalgae are super foods, to help restore our personal and planetary health.
