The long-held belief that milk and dairy products are essential for bone health has been challenged in recent years. As the global health community shifts towards more plant-based diets for environmental and ethical reasons, it's crucial to examine the evidence behind these claims. We asked experts about the latest research to answer the question: why more dairy doesn't necessarily mean fewer fractures.

“'Calcium is essential for bone health, but it's not the only nutrient that matters. A balanced diet, rich in various nutrients and adequate in calories, is key,' says Dr. Susan Lanham-New, Senior Research Fellow at the University of Surrey.”

The calcium myth?

The notion that dairy products are the best source of calcium has been questioned. While it's true that dairy contains calcium, other plant-based foods can provide comparable amounts.

Plant-based diets and bone health

Several studies have found that well-planned plant-based diets can support bone health. The key is ensuring adequate intake of calcium and other essential nutrients.

“'A well-planned plant-based diet can provide all the nutrients we need for bone health. It's about variety and balance,' says Dr. Emma Derbyshire, Public Health Nutritionist.”

Exercise and vitamin D

Regular exercise and adequate vitamin D intake are also crucial for bone health. Weight-bearing and resistance exercises stimulate bone growth, while vitamin D aids calcium absorption.

The environmental impact

The environmental impact of dairy production is significant. Plant-based alternatives often have a lower carbon footprint and require less water and land.
