Guide de santé pour le troisième âge is a French‑language paperback that offers practical advice for older adults seeking to maintain vitality and well‑being. Author Jacques Santoni draws on medical knowledge and everyday experience to discuss balanced nutrition and safe physical activity. He also covers routine health screenings and management of common age‑related conditions including arthritis, hypertension, diabetes, and heart disease. The book also addresses mental health and social engagement, and offers strategies for preserving independence. Illustrated with clear tables and simple explanations, it aims to empower readers to make informed choices about lifestyle and healthcare. First published in 1986 by Guy Le Prat and later reissued by GRUND, the guide remains a useful reference for seniors and caregivers, as well as health professionals interested in promoting healthy aging.
