Dairy products
Consuming too many dairy products is harmful to bones. The reason is that the body absorbs very little calcium from milk and dairy products, and the body uses calcium to neutralize acidity.
Salt
Salt and an excessively salty diet can make bones brittle. A Japanese study showed that women who ate very salty foods were more likely to have osteoporosis than those who ate normally or consumed a minimal amount of salt.
Carbonated drinks
Carbonated drinks are a very unhealthy choice. Some studies have shown that they also negatively affect bone health because they contain acids that have an extremely harmful effect on bones.
