Osteoporosis patients should eat less caffeine-rich, oxalic acid-rich, pickled and spicy stimulating, high-sugar foods. 1. Caffeine-rich: Reduce the consumption of strong tea, coffee and other foods. Theophylline and caffeine will inhibit the absorption of calcium in the gastrointestinal tract on the one hand, and accelerate the loss of calcium on the other, aggravating the symptoms of osteoporosis. 2. High oxalic acid content: Reduce the consumption of spinach, leeks and other foods. This type of food will affect the gastrointestinal tract on the absorption of calcium, pay special attention to this type of food can not be eaten with high-calcium foods, such as spinach and tofu soup with food or with fish soup with food. Calcium oxalate is easily formed, leading to stone formation and aggravating osteoporosis. 3. Pickled and spicy stimulation: reduce eating salted vegetables, canned food, bacon, barbecue, hot pot and other foods. High-salt foods will cause an increase in urinary calcium, accelerate calcium ion loss, which in turn affects calcium absorption and aggravates osteoporosis. 4. High-sugar foods: Reduce the consumption of cakes, drinks, chocolate and other foods. Too much sugar can affect the absorption and utilization of calcium, which will aggravate osteoporosis. Osteoporosis should be standardized under the guidance of a doctor, and balanced, adequate and comprehensive nutrition should be ensured.
