About this episode

Monica discusses the relationship between calcium intake and kidney stones, debunking common myths and providing evidence-based dietary advice.

874. If you're prone to kidney stones, you've probably been told to cut back on calcium. If you're worried about your bones, you've been told to get more. So which is it? Turns out it's a false choice. The old advice to restrict dietary calcium doesn't lower your risk of calcium stones -- it can raise it, while leaving your bones more vulnerable to loss. In this episode, Monica breaks down why the calcium in your food behaves so differently from the calcium in a pill, when timing it with a meal actually makes a difference, and how much calcium and vitamin D you really need if you're filling a gap. She also looks at how sodium, animal protein, and fluid intake each shape your kidney stone risk, and why the same evidence-based eating habits that guard against osteopenia and protect bone health as you age are also the ones that protect your kidneys.
