Eating foods that provide, by day's end, about three times the recommended daily amount of copper may help overweight or obese women retain calcium in their bones while they're dieting.
That's indicated by a study with overweight women aged 25 to 35.
Some of the women in the study received daily supplements of 3 milligrams (mg) of copper. The others received supplements of only 1.23 mg.
All participants were then put on a weight-loss diet for four months.
Women who took 3 mg of copper retained more calcium in their bones than those who took 1.23 mg of supplemental copper.
The current Recommended Dietary Allowance for copper is 0.9 mg for women older than 19 years.
The copper study, conducted by scientists at the ARS Grand Forks (N.D.) Human Nutrition Research Center, suggests the current allowance for copper may not be adequate during weight loss.
