血管钙化是补钙闹的？

Group 1 - The core issue of vascular calcification is related to chronic inflammation of the vascular wall and calcium-phosphorus metabolism imbalance, rather than simply excessive calcium supplementation [2] - Vascular calcification can be protective in nature, as calcified plaques are less likely to rupture compared to non-calcified ones, thereby reducing the risk of cardiovascular events [1] - The recommended daily intake of calcium for adults is between 800 to 1000 mg, with a safe upper limit of 2000 to 2500 mg according to the American Heart Association [3] Group 2 - Osteoporosis is a common metabolic bone disease characterized by a decrease in bone density, leading to increased fracture risk, and calcium supplementation is a primary treatment method [2] - Reasonable calcium supplementation generally does not exacerbate vascular calcification, with risks only associated with long-term excessive intake or calcium metabolism disorders [2] - The average dietary calcium intake is approximately 400 mg per day, and common calcium supplements provide around 600 mg, making a total intake sufficient for health [3]
