In the ever-evolving field of nutrition, understanding the science of aging is essential for dietitians aiming to support clients in achieving healthy longevity. This comprehensive workshop delves into the complex biological processes of aging, including the role of oxidative stress and chronic inflammation, two key drivers of age-related decline. Participants will explore the latest research on caloric restriction and its potential benefits for aging, along with targeted nutritional strategies designed to combat these physiological challenges. The course will provide an in-depth analysis of essential proteins, micronutrients, and dietary patterns that support healthy aging, including the role of probiotics in maintaining gut health and overall vitality. We’ll examine popular diets such as the Mediterranean and DASH diets, assessing their efficacy in promoting longevity and preventing age-related diseases. Special focus will be placed on the practical application of these nutritional strategies in clinical practice, equipping dietitians with the tools to develop personalized nutrition plans that cater to individual needs.
