Introduction
Living a healthy and active life requires proper nutrition that varies according to our age group. Rapid growth during childhood requires different eating patterns than the health maintenance process experienced during adulthood, plus older people need different nutrition than they do in old age. This complete age-appropriate nutrition guide will show you how to achieve your body’s optimal fuel needs at any stage of your life. In this guide, you will find evidence-based healthy eating tips for every age group, useful for both parents who need food for their children and working adults as well as seniors who want to stay physically active.
Why Nutrition Matters Across the Lifespan
Good nutrition serves two important purposes in life, as it helps prevent disease as well as enables individuals to thrive. Intake of essential vitamins and minerals enables proper growth, strengthens the immune system, provides clear thinking, and prevents persistent illnesses. The World Health Organization reports that proper nutritional intake can reduce the risk of heart problems and diabetes and the incidence of obesity by up to 80% during adulthood.
