How to Rebuild Bone Density: The Truth About Calcium | Dr Connie Weaver
Join us as Dr. Connie Weaver, Distinguished Research Professor at San Diego State University and National Academy of Medicine member, reveals the hidden science of bone loss, calcium bioavailability, and the gut-bone axis. Discover why fractures kill more people than most realize, why modern plant-forward diets are inadvertently blocking mineral absorption, how soluble corn fiber halts postmenopausal bone loss, and the strict 500mg calcium dosing rule you need to know. Osteoporotic fractures outnumber new diagnoses of heart disease and cancer combined, with 20% of hip fracture patients dying within 12 months. Yet bone health remains one of the most overlooked pillars of healthspan. In this episode, we sit down with Dr. Connie Weaver, one of the world's foremost authorities on mineral metabolism and bone remodeling. Dr. Weaver explains why nutrition plays a permissive role alongside resistance exercise, how the estrogen crash during menopause accelerates osteoclast bone resorption, and why high-dose Vitamin D trials have failed to stop fractures in the general population. She breaks down her landmark 3-decade research modeling calcium bioavailability across global diets (now integrated into Cronometer), revealing how high-oxalate and high-phytate plant diets are driving widespread calcium deficits. Finally, Dr. Weaver shares her groundbreaking discovery on the gut-bone axis - demonstrating how prebiotic soluble corn fiber feeds fiber-fermenting bacteria to stop postmenopausal bone loss - and clarifies the truth about calcium supplements and arterial plaque.
