The relationship between blood calcium and blood phosphorus is generally close. Almost all blood calcium exists in plasma, and the blood calcium level in healthy individuals fluctuates very little, maintained at around 2.25~2.75 mmol/L. Phosphorus in the blood exists in two forms: organic phosphorus and inorganic phosphorus. Three-quarters of the phosphorus in the blood is organic, and one-quarter is inorganic. Inorganic phosphorus mainly exists in the form of phosphates, forming a buffering system in the blood. Phosphates in cells participate in many enzymatic reactions and are components of nucleotide coenzymes. The relationship between blood phosphorus and blood calcium is generally close. The product of blood calcium and blood phosphorus concentrations in healthy individuals is 30~40 mg/dl. When the product of blood calcium and blood phosphorus concentrations exceeds 40 mg/dl, calcium and phosphorus are deposited in bone tissue in the form of bone salts. A product of blood calcium and blood phosphorus concentrations less than 35 mg/dl hinders bone calcification and may even cause bone salt dissolution, affecting bone formation. It is recommended to maintain a light diet, including plenty of fresh vegetables and fruits such as cantaloupe and tomatoes. Avoid spicy and irritating foods such as spicy chicken nuggets and spicy chicken thighs.
