Chromium supplement protects the heart of diabetics
Prolonged QT interval is a heart rythm disturbance that can cause fatal heart arrhythmias.
A prolonged QT interval is tied to decreased insulin sensitivity, elevated blood sugar, and
elevated levels of insulin in type 2 diabetics. In this study 30 diabetics took 1,000 mcg of
chromium a day for 3 months, followed by an inactive placebo for 3 months. Another 30 diabetics
took the placebo for the first 3 months and then were switched over to the chromium for the
2nd 3 month period. At the start of the study the QT interval was similar in both groups,
422 milliseconds in the first and 425 in the second. The QT interval shortened to 406
milliseconds in the chromium group and was significantly shorter than the placebo group.
In the second 3 month period the QT interval shortened in the other group that was switched
to chromium versus placebo. At the end of the trial the QT interval remained shorter than at
the beginning of the trial in both groups. Blood insulin levels also dropped significantly in
both groups. Chromium supplementation at 1,000 mcg per day lowers heart risk according to this
study. The study is published in the April 2005 American Heart Journal.
Another study links garden pesticides to Parkinson's disease
Researchers from the University of Aberdeen in Scotland have concluded that common back yard
pesticides can increase the risk of developing Parkinson's disease and the more pesticide the
gardener is exposed to the more likely they are to develop this degenerative brain disease.
In questioning 767 Parkinson's patients vs. 1,989 healthy individuals it was found that back
yard ameteur gardeners had a 9% more likely to develop Parkinson's disease and farmers were
43% more likely. Being knocked unconscious increased the risk. Having a family history of
Parkinson's disease increased the risk by 350%. The study is published in this weeks
issue of New Scientist.
