The Myth That Protein Reduces Bone Health

Despite all the calcium that dairy contains, some believe that its high protein content can cause osteoporosis.

The reason is that when protein is digested, it increases the acidity of the blood. The body then pulls calcium from the blood to neutralize the acid.

This is the theoretical basis for the acid-alkaline diet, which is based on choosing foods that have a net alkaline effect and avoiding foods that are “acid forming.”

However, there really isn’t much scientific support for this theory.

If anything, the high protein content of dairy is a good thing. Studies consistently show that eating more protein leads to improved bone health (4, 5, 6, 7).

Not only is dairy rich in protein and calcium, it’s also loaded with phosphorus. Full-fat dairy from grass-fed cows also contains some vitamin K2.

Protein, phosphorus and vitamin K2 are all very important for bone health (8, 9).

Summary

Not only is dairy rich in calcium, it also contains large amounts of protein and phosphorus, all of which are important for optimal bone health.
