Osteoporosis
Osteoporosis is the loss of calcium mineralisation from bones, resulting in
decreased bone strength. In extreme cases, bones become prone to breakage and the spine may even progressively
collapse under body weight. Women are more prone to osteoporosis than men.
While osteoporosis is generally a problem of old age, younger people who consume large amounts
of ‘coke’ type soft drinks may experience some bone calcium loss as a consequence of their intake of phosphoric
acid. This is ejected from the body at the expense of calcium in bones, and may have a detrimental effect in
marginal cases (i.e., where calcium uptake is already inadequate).
Risk factors for osteoporosis include prolonged intake of the prescription drug prednisone or
any other glucocortioid, smoking, low body mass index, estrogen deficiency, early menopause (<45 years), low
calcium and vitamin D intake, high alcohol intake, and a family history of the condition. Coeliac disease can lead
to calcium deficiency and osteoporosis in people with an otherwise adequate calcium intake due to the inability to
absorb calcium.
Osteoporosis is usually treated with biphosphonates, a type of drug that reduces the rate of
release of calcium from bone tissue. Treatment is generally accompanied by calcium supplementation. This in turn
should be accompanied by supplementation with magnesium and with vitamin D.
Prevention by means of supplementation is seen as of greater value than treatment after the
problem has become severe.
A deficiency in essential fatty acids (including GLA and EPA, an omega-3 fatty acid) can be
another cause of osteoporosis. Studies have shown that supplements of GLA and EPA together help maintain or
increase bone mass. Essential fatty acids may also enhance calcium absorption, increase calcium deposits in bones,
diminish calcium loss in urine, improve bone strength, and enhance bone growth, all of which may contribute to
improved bone mass and, therefore, strength.
