Osteoporosis

Nearly 25 million Americans suffer with osteoporosis and the related complications of thin, porous bones prone to fracture.  Today, I’d like to start a series on the subject of calcium and strong bones.

Everyone believes that strong bones are merely the result of how much calcium you can pour down.  In reality, there are numerous factors such as the type of calcium, other vitamins and minerals, physical activity and your own internal chemistry that will undermine your efforts regardless of your calcium intake.  Many researchers believe that your chemistry, specifically your pH, may be one of the most important factors.  pH in your body is the same as in your swimming pool – it’s the balance of acid and base.  By design, we are meant to be slightly basic or “alkaline” and many believe that all disease exists only in an acidic environment.

In terms of strong bones, as we become more acidic (pH less than 7.3) the activity of the cells that break down bone (osteoclasts) is increased and the activity of the cells that build bone (osteoblasts) is decreased.  This means in an acidic environment, you will continuously be losing bone strength.  However, the opposite phenomenon seems to happen in an alkaline environment and you gain bone strength.  The question then should be how do we stay alkaline, and what would make our bodies acidic?

The key to staying alkaline is the same as the key to reducing inflammation in the body.  You must eat a diet high in alkaline foods such as fruits and vegetables.  The primary things that increase acidity in our bodies are diets high in protein and excessive amounts of emotional stress.  Do you know what food is relatively high in dietary protein . . . dairy.  Ooops!  More on this next week.
