Yes, taking soda is bad for the bones because it calcium absorption by the body and favors loss of bone mass, increasing the risk of fractures and osteoporosis.
Soft drinks are rich in phosphor, present in phosphoric acid. In the human body, the calcium is always connected to phosphorus. They are called metabolic twins, because where one is, there is the other also.
When drinking soda, normal, diet, light or zero, the body needs to fetch the calcium from the bones to process the large amount of phosphorus ingested.
This imbalance contributes to the loss of bone mass, increasing the risk of osteoporosis.
In addition, phosphorus and calcium compete with each other to be absorbed by the body. This means that taking soda hinders the absorption of calcium present in food.
Another substance that damages bones is the caffeine, present in large quantities in cola-based soft drinks such as Coca-Cola and Pepsi.
In excess, caffeine increases the concentration of calcium in the muscles, thereby blocking its reuptake into the blood.
Caffeine also increases the production of the cells responsible for bone resorption, that is, they remove calcium from the bones.
The result is a reduction in bone mass, with a consequent increase in the risk of fractures, especially in women.
