What condition is prevented by adequate levels of calcium?

Adequate levels of calcium are essential for maintaining strong bones and overall skeletal health. Rickets is a condition characterized by the softening and weakening of bones in children, primarily due to a deficiency of vitamin D, calcium, or phosphate. Calcium plays a critical role in bone formation and growth, and insufficient calcium intake can lead to rickets by compromising the mineralization process within the bones.

While conditions like goiter, anemia, and poor teeth can be problematic and are associated with different nutritional deficiencies or health issues, they do not specifically relate to calcium levels. Goiter is related to iodine deficiency, anemia often arises from iron, vitamin B12, or folate deficiencies, and poor dental health can be influenced by various factors including oral hygiene and dietary sugar intake rather than solely being a consequence of low calcium levels. Thus, the direct relationship between calcium and the risk of developing rickets makes it the correct choice in this context.
