Osteoporosis is caused by a decrease in the calcium content in the bone, and you should eat less food that affects calcium absorption, such as: carbonated beverages, food containing phosphoric acid, high salt diet, smoking and alcohol. 1. Carbonated beverages: Drinking a lot of carbonated beverages such as Coke, Sprite, etc. will affect calcium absorption, leading to calcium loss and aggravating the risk of osteoporosis. 2. High-phosphorus foods: Excessive intake of high-phosphorus foods such as meat, nuts, etc. will cause calcium-phosphorus imbalance, and the chemical reaction between calcium and phosphorus will form substances that are not easily absorbed, resulting in calcium being excreted from the body. 3. High-salt diet: too much salt will affect the body’s absorption of calcium, but also may lead to the loss of the body’s original calcium, because salt contains sodium, sodium will be discharged by the kidneys every day, calcium will also be discharged in proportion. 4. Tobacco and alcohol: Osteoporosis patients who smoke and drink a lot of alcohol for a long time will increase the risk of osteoporosis. It is suggested that patients should adjust their dietary structure, avoid carbonated drinks, high phosphorus food, consume food with less salt and less oil, quit smoking and drinking, and can exercise properly and eat more high-calcium food.
