Beer is a rich source of silicon and may help prevent osteoporosis

A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Beers containing high levels of malted barley and hops are richest in silicon.

A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Researchers from the Department of Food Science & Technology at the University of California, Davis studied commercial beer production to determine the relationship between beer production methods and the resulting silicon content, concluding that beer is a rich source of dietary silicon.
Details of this study are available in the February issue of the Journal of the Science of Food and Agriculture, published by Wiley-Blackwell on behalf of the Society of Chemical Industry.
"The factors in brewing that influence silicon levels in beer have not been extensively studied" said Charles Bamforth, lead author of the study. "We have examined a wide range of beer styles for their silicon content and have also studied the impact of raw materials and the brewing process on the quantities of silicon that enter wort and beer."
Silicon is present in beer in the soluble form of orthosilicic acid (OSA), which yields 50% bioavailability, making beer a major contributor to silicon intake in the Western diet. According to the National Institutes of Health (NIH), dietary silicon (Si), as soluble OSA, may be important for the growth and development of bone and connective tissue, and beer appears to be a major contributor to Si intake. Based on these findings, some studies suggest moderate beer consumption may help fight osteoporosis, a disease of the skeletal system characterized by low bone mass and deterioration of bone tissue.
The researchers examined a variety of raw material samples and found little change in the silicon content of barley during the malting process. The majority of the silicon in barley is in the husk, which is not affected greatly during malting. The malts with the higher silicon contents are pale colored which have less heat stress during the malting process. The darker products, such as the chocolate, roasted barley and black malt, all have substantial roasting and much lower silicon contents than the other malts for reasons that are not yet known. The hop samples analyzed showed surprisingly high levels of silicon with as much as four times more silicon than is found in malt. However, hops are invariably used in a much smaller quantity than is grain. Highly hopped beers, however, would be expected to contain higher silicon levels.
No silicon was picked up from silica hydrogel used to stabilize beer, even after a period of 24 hours and neither is there pick up from diatomaceous earth filter aid.
The study also tested 100 commercial beers for silicon content and categorized the data according to beer style and source. The average silicon content of the beers sampled was 6.4 to 56.5 mg/L.
"Beers containing high levels of malted barley and hops are richest in silicon," concludes Dr. Bamforth. "Wheat contains less silicon than barley because it is the husk of the barley that is rich in this element. While most of the silicon remains in the husk during brewing, significant quantities of silicon nonetheless are extracted into wort and much of this survives into beer."
need to compare this to silicic acid content in mineral water re Dr. Exley's work (curing alzheimers? with Al chelation/antagonism)
sorry, no. Just a user wrote nonsense, one too many times and I decided to permit them to write their nonsense elsewhere, moved any posting that poster had responded to, over to "the funny farm" forum. Nothing to do with your posting and if your thing got moved, it was totally inadvertent
the internet has changed soo much.
and I grew up with some black'n'white t.v.'s in the house.
12 inch by 12 inch.
you got 4-5 stations.
and it if you wanted to adjust the volume...
well you had to get up off the couch and turn a knob.
I just saw an article 2 days ago.
not saying it is right....
but it was a police chief in some city saying...
one of the reasons for the rise in the homicide rate here is........ well instant media and all the attention the small amount of white cops killing black suspects gets.
There are 3-4 highly publicized cases a year.
people with cell phone cameras capturing this or that.
internet sites talking about this or that.
and according to his theory......
it has made cops 'gun-shy'.
for lack of a better expression.
not saying that is true.
but politics has changed.
if this technology existed in the past.....
well most of the higher up politicians would have had a hard time getting or staying elected.
Romney took it on the chin for a comment that was recorded at a private fundraiser.
Interesting study done on dolphins with metabolic syndrom / diabetes like symptoms;
"Heptadecanoic acid, also called margaric acid or C17:0, is a saturated fat found in dairy fat, rye, and some fish. The NMMF study showed no detectable heptadecanoic acid in nonfat dairy product and some amount in low fat dairy products. The highest levels were found in whole fat milk, yogurt, and especially butter. The fish with the highest heptadecanoic acid content was mullet.
"We hypothesize that widespread movement away from whole fat dairy products in human populations may have created unanticipated heptadecanoic acid deficiencies," said Venn-Watson, "and, in turn, this dietary deficiency may be playing a role in the global diabetes pandemic." Today, the Centers for Disease Control and Prevention estimates that over 86 million people in the U.S. have metabolic syndrome--tone in every three adults."
