Dietary therapy for osteoporosis is an important treatment method. First, eat foods that are high in calcium. Second, consume high protein diets; third, moderately supplement vitamins. Avoid high-salt diets, because the main component of salt, sodium chloride, affects bone metabolism. Sodium chloride primarily increases the excretion of calcium, meaning that higher levels of sodium chloride lead to higher levels of calcium excretion. Therefore, high sodium diets can increase the amount of calcium excreted in urine; excessive intake of sodium chloride can lead to further loss of calcium. Thus, it is essential to focus on a low-sodium diet.
