Low chromium levels may raise heart attack risk
Thu Jul 21, 2005 9:04 PM ET
NEW YORK (Reuters Health) - Low body levels of chromium, a mineral =
involved in carbohydrate and fat metabolism, are associated with an =
increased risk of heart attack, according to a new report. However, the =
value and safety of chromium supplementation remains to be determined.
Chromium deficiency leads to blood sugar problems that cannot be =
controlled with insulin, researchers explain in the American Journal of =
Epidemiology, but the association of chromium intake with heart-related =
outcomes is largely unknown.
Dr. Eliseo Guallar from the Welch Center for Prevention, Epidemiology, =
and Clinical Research in Baltimore, and colleagues measured chromium =
levels in 684 men who survived a heart attack and in a similar number of =
men who'd never experienced one. Chromium was measured in toenail =
clippings because this provides a better indication of levels on a =
long-term basis compared with measurement of blood levels.
Chromium levels were lower among older individuals, declining about 9 =
percent with each decade increase of age, the investigators report. =
Levels were also lower in those with high blood pressure.
Chromium levels were also 13-percent lower in heart attack patients than =
in comparison subjects, the researchers note. Further analysis showed =
that subjects with the highest levels were 35-percent less likely to =
have a heart attack than those with the lowest levels.
"Although there are no national survey data on chromium intakes, a study =
of self-selected diets of US adults indicated that the chromium intake =
of a substantial proportion of subjects may be well below" the levels =
that are considered adequate, the researchers point out.
However, "considerably more evidence" is needed to substantiate claims =
that chromium supplementation will improve sugar control, weight loss, =
exercise capacity, and longevity, the team says, "as well as to show the =
long-term safety of chromium supplementation in humans."
