Tired of fad diets? Good — because this isn't one. In this episode of the Over 50 Health & Wellness Podcast, host Mark Sullivan shares what actually changes about nutrition after 50 and how to eat for energy, strength, and healthy aging — no restriction, no guilt, no gimmicks. Just real food and simple, sustainable habits.

Learn why you need fewer calories but more nutrients, how much protein and fiber you really need, the vitamins that get harder to absorb with age (like B12), how to cut sodium and added sugar without feeling deprived, and easy solutions for cooking for one or eating well on a budget.
