Introduction: Calcium, An Essential Mineral
Calcium is the most abundant mineral in the human body, representing approximately 1.5 to 2% of total body weight. More than 99% of body calcium is stored in bones and teeth. Dairy products constitute the richest and most bioavailable dietary source of calcium.
Bioavailability of Dairy Calcium
Dairy calcium has an exceptional bioavailability of 30 to 35%, significantly higher than plant sources (5 to 20%).
Scientific Evidence
Framingham Osteoporosis Study (2017)
This 30-year longitudinal study of 5,000 participants demonstrated that daily consumption of 3 servings of dairy products was associated with a 6% increase in bone mineral density and a 42% reduction in the risk of osteoporotic fractures.
Conclusion
Scientific evidence is irrefutable: dairy calcium is essential for bone health at all stages of life. Daily integration of 3 to 4 servings of quality dairy products constitutes a simple and effective nutritional strategy.
