N utrients are substances that the body essentially needs so the body can do its function properly, one of the examples are minerals calcium and phosphorus. The highest sources of calcium minerals can be found in foods such as dried shrimp and dried anchovies, while the highest source of phosphorus are found in dried anchovies and milk powder. The average of recommended daily needs of minerals calcium for adults are 500-800 mg while phosphorus are 400-500 mg. The mainfunctions of minerals calcium and phosphorus are to help the process ofcalcification of bones and teeth. Calcification process begins with the deposition of calcium and phosphorus on the mineral matrix of bone and teeth that form mineral crystals. Then, These crystals are combined with calcium hydroxide which are called hydroxyapatite. The process of calcification in bones are characterized by hardening of the bones while in the teeth are characterized by hardening of the email and dentin. Vitamin D (1,25-dihydroxycholecalciferol),parathyroid hormone is a factor which helps absorption of calcium andphosphorus mineral. Calcitonin hormone that regulates levels in the blood. Deficiency of mineral calcium and phosphorus in the bone can cause osteoporosis, a disease that cause a reduction in bone mineral density. Besides that, it can also cause a disease that softening the bone matrix that is called rickets in children while in adults is called osteomalacia The consequences of mineral calcium and phosphorus deficiency in the process of calcification may lead to the occurrence of hypoplasia email, which are the structural abnormalities of the enamel. So, the minerals calcium and phosphorus is needed for the process of calcification of bones and teeth and by consuming foods that contain lots of minerals calcium and phosphorus can be spa.red from the diseases above.
