• Sommario/riassunto: This publication is based on an FAO/IAEA coordinated research project (CRP) and provides insight into the application of induced mutation and in vitro techniques for the improvement of well known fruit trees such as citrus, mango, avocado and papaya, as well as more exotic fruit trees such as litchi, annona, jujube, carambola, pitanga and jaboticaba. The latter are of particular importance due to their adaptation to harsh environments and their high potential as basic food and micronutrient providers for populations in poorer and more remote regions. The findings of the CRP show that application of radiation induced mutation techniques in tropical and subtropical fruit trees can contribute to improving nutritional balance food security, and to enhancing the economic status of growers.

• Sommario/riassunto: This book explores the relationship between nutrition and cognitive health in the aging brain. Written by Richard A. Dienstbier, Professor Emeritus of Psychology, it examines how dietary choices and specific nutrients impact brain function, emotional well-being, and resilience against cognitive decline. The author discusses the concept of 'healthspan' versus 'lifespan,' emphasizing mental preservation and cognitive longevity. Drawing on recent scientific research, the book evaluates dietary approaches like the Mediterranean diet, the role of vitamins, minerals, and supplements, and their effects on brain health and mood. It also tackles inconsistencies in nutrition studies and provides evidence-based insights into smart dietary choices that may delay dementia and enhance mental clarity. Intended for an audience interested in psychology, aging, and health, the book balances scientific rigor with practical dietary advice.
