Milk has long been sold as the key to strong bones, but research challenges that claim: many people don’t tolerate dairy, calcium needs are lower than advertised, and higher milk intake doesn’t necessarily prevent fractures. Politics and industry marketing helped set “three glasses a day,” even though healthy bones depend more on overall diet and lifestyle—things like vitamin D, movement, and avoiding soda, excess sugar, and stress that drive calcium loss. Dairy may be helpful for some diets, but it can also trigger bloating, acne, congestion, or digestive issues. The good news is that strong bones and good nutrition are still very doable without cow’s milk—think leafy greens, sardines, almonds, chia, and sunshine for vitamin D.

In this episode, I discuss, along with Dr. David Ludwig and Dr. Elizabeth Boham why bone health depends more on diet, lifestyle, and nutrient balance than on dairy.

David S. Ludwig, MD, PhD, is an endocrinologist and researcher at Boston Children’s Hospital, Professor of Pediatrics at Harvard Medical School, and Professor of Nutrition at the Harvard T.H. Chan School of Public Health. He co-directs the New Balance Foundation Obesity Prevention Center and founded the Optimal Weight for Life (OWL) program, one of the nation’s largest clinics for children with obesity. For over 25 years, Dr. Ludwig has studied how diet composition affects metabolism, body weight, and chronic disease risk, focusing on low glycemic index, low-carbohydrate, and ketogenic diets. Called an “obesity warrior” by Time Magazine, he has championed policy changes to improve the food environment. A Principal Investigator on numerous NIH and philanthropic grants, Dr. Ludwig has published over 200 scientific articles and three books for the public, including the #1 New York Times bestseller Always, Hungry?

Dr. Elizabeth Boham is Board Certified in Family Medicine from Albany Medical School, and she is an Institute for Functional Medicine Certified Practitioner and the Medical Director of The UltraWellness Center. Dr. Boham lectures on a variety of topics, including Women’s Health and Breast Cancer Prevention, insulin resistance, heart health, weight control and allergies. She is on the faculty for the Institute for Functional Medicine.
