Trace minerals: silica
Silica is another trace mineral that like Boron receives little attention in the popular press.
There is a chemical compound called silicon dioxide which is the chemical name for this trace mineral. Since the 9th century it has been known for its hardness.
Silica is most commonly found in nature as sand or quartz. If you have sufficient amounts of this trace mineral in your diet you will have stronger bones, better skin, more flexible joints.
It seems to boost the benefits of calcium, glucosomine and vitamin D. And scientists believe that it provides defense against aluminum toxicity - something that has been associated with Alzheimer's disease.
When we are very young we have more silica and less calcium in our bodies. As we age the ratio between these twominerals reverses.
This trace mineral is a major ion in the bone-forming cells in young, uncalcified bone. As the bone matures, the concentrations declines and deposits of calcium and phosphorous increase. But the trace mineral is important. It acts as a regulating factor for calcium and phosphorous in bone tissue. ( Life Extension Magazine April 2003.)
Major nutritional sources of this trace mineral:
Although the mineral is found in soil and sand, none of us are eating that! Bananas, beer and string beans seem to be the best food sources. An article in the Am. J. Clin. Nutrition in may 2002 noted that men tended to have greater silicon in their bodies than women - the authors assumed that was because men drank more beer!
For your bones. As we age, there appears to be a reduction in the amount of our silica. Some English researchers with funding from the British Food Standars Agency are studying the amount of the mineral in older British Women andthe possible relationship betwen this mineral and bone health - and whether silicon is essential for proper useof two necessary bone building vitamins: Vitamin D and Vitamin K.
Meantime, do eat bananas and string beans (Note I am not advocating beer drinking since alcohol is a problem for thosestrong bones. See: Alcohol Osteoporosis Connection
You might want to check to see if this important mineral is included in your daily multi-vitamin and/or your calcium supplement.
One of the reasons I use Advacal Ultra, rather than the plain Advacal as my calcium supplement is that Advacal Ultra does includes micro nutrients. It has 90mg of this important trace as well as others such as boron, manganese etc.
