What percentage of milk is comprised of calcium?

Milk is an important source of calcium, which is a vital mineral for bone health and various metabolic functions. The correct answer indicates that approximately 1% of milk is composed of calcium. This aligns with nutritional data that highlights how milk contributes to dietary calcium intake.

Calcium is found in milk in relatively small percentages compared to the total volume, which consists primarily of water and other nutrients. Given that milk typically contains around 120 milligrams of calcium per 100 milliliters, it simplifies to about 1% in terms of composition.

Other percentages, such as 0.5%, 2%, and 1.5%, do not accurately represent the calcium content found in typical milk. This reflects an understanding of nutritional facts regarding dairy products, reinforcing the significance of milk as a good dietary source of calcium for those who include it in their diets.
