Consumption of calcium-rich foods can help increase bone density, such as seafood, dairy products, and nuts. Note that medication is also needed if low bone density is caused by pathologic factors. 1. Seafood: such as shrimp, kelp, etc. 2. Dairy products: such as milk powder, fresh milk, cheese, yogurt, etc., calcium content and absorption rate are relatively high. 3. Nuts and products: such as sesame paste, peanuts, sesame seeds, etc., calcium content is also high. 4. Beans and green vegetables: although high in calcium, their calcium absorption rate is low. In addition to supplementing calcium-rich foods, you can also sunbathe frequently to promote the absorption and utilization of calcium. Although the above foods may have the effect of calcium supplementation, the effective dosage ingested from daily consumption is limited and generally cannot achieve a therapeutic effect. If you want to achieve certain therapeutic effects, it is recommended that you undergo regular treatment under the guidance of a doctor.
