[IP] Re: Chromium.


     According to the PDR for Nutritional Supplements, Chromium plays an 
important role in normal carbohydrate metabolism.  It is also necessary in 
the the maintenance of normal glucose tolerance.  It presence in the diet 
also seems to have an effect upon peripheral neuropathies too.  Important 
thing is to get the right form.  Nutritional chromium is trivalent.  
Poisonous stuff is hexavalent.  Good food sources are: whole grains, cereals, 
spices like black pepper, thyme, mushrooms, brown sugar (gee that one doesn't 
seem to help), coffee, tea, beer (yes!), wine and meat products.  Brewer's 
yeast is a good sources as well, however fruits and veggies are considered 
poor sources.  Side note, Chromium is also believed to have 
hypocholesterolemic and anti-atherogenic activity.
     Chromium is believed to increase insulin binding, increased insulin 
receptor numbers, and increase insulin receptor phosphorylation (chemical 
process that activates the receptors), it also inactivates the 
phosphotyrosine phosphatase which inactivates the insulin receptors.  The 
Nutritional PDR really stresses that Brewer's Yeast is really rich in 
     Obviously, those folks who are allergic should avoid it.  Also pregnant 
women and nursing mothers should avoid excessive doses (above 200 
micrograms).  Excessive doses (above 200 micrograms) can lead to anemia, 
thrombocytopenia, hemolysis, liver dysfunction, renal failure, and 
     Interactions with Beta Blockers produce a mildly elevated serum HDL 
level.  Ascorbate increases the absorption of chromium.  Foods rich in phytic 
acid (unleavened bread, raw beans, seeds, nuts, some grains, and soy 
isolates) decrease the absorption of chromium.
     Be careful and read the size of the dose of the tablets or capsules you 
are using because there is a great deal of varience.
