Limit your intake of salt to one teaspoon per day. Salt, or more specifically sodium, causes calcium loss, weakening bones over time.

According to experts, you would lose around 40 milligrams of calcium in urine for every 2,300 milligrams of sodium, the amount of sodium you should get in a day (present in a teaspoon of salt). In a study conducted on post menopausal women, it was found that women who consumed a high-sodium diet lost more bone minerals in comparison to those who didn't. Apart from table salt, salt also shows up in nearly all processed foods like whole grain breads, breakfast cereals, and fast foods, making up 75 percent of the total sodium consumption.

Cooking without salt and can help, but limiting your consumption of processed foods provides the most help. Eating plenty of potassium-rich foods (such as sweet potatoes, bananas, tomatoes, and spinach) can also help decrease the loss of calcium as potassium helps balance sodium levels in blood.
