Clinically, there is no clear stipulation that osteoporosis should not eat “three kinds of vegetables”, osteoporosis groups should try to eat as little as possible spinach, leeks and other vegetables containing high oxalic acid, and drink less highly carbonated beverages. 1. Oxalic acid will combine with calcium in food to form calcium oxalate precipitates and affect the body’s absorption of calcium, which in the long run will lead to the loss of bone calcium and further promote osteoporosis. Common vegetables including spinach and leek are rich in oxalic acid, so it is not recommended to eat ribs with spinach to affect calcium absorption. 2. In addition to vegetables, osteoporosis group should also try to avoid drinking cola and other highly carbonated beverages, with oxalic acid, carbonic acid and calcium combined to form calcium carbonate, will also inhibit the body’s normal absorption of calcium. Osteoporosis patients should plan their daily diets under the guidance of medical professionals in order to minimize calcium loss.
