When a food label claims that the product will "build strong bones," the assumption can be made that

The answer is that the food is rich in calcium and vitamin D. ca2+ ions is deposited in the bone matrix as calcium phosphate crystals and are what calcify the bone and give it its physical strength. This prevents osteoporosis and hence reduces the susceptibility to bone fractures. Vitamin D is significant in the differentiation of  hypertrophic chondrocytes and calcification processes.
