Final answer:
Marginal intake of calcium can lead to kidney stones.
Step-by-step explanation:
The marginal intake of calcium can lead to the formation of kidney stones.
Calcium metabolism is important for maintaining the balance of calcium in the body. When there is a reduction in calcium absorption from the intestines, the excretion of calcium from the kidneys increases, which can contribute to the formation of kidney stones.
Hyperparathyroidism, a condition characterized by high serum calcium levels, can also result in kidney stone formation.
