Calcium Overload

摘要

Calcium doesn't grow in orange groves, but it abounds in orange juice these days—not to mention margarine, breakfast cereal, pancake mix and energy bars. Food makers introduced a record 119 calcium-fortified products last year, nearly three times the number launched in 1998. "Everywhere you turn, it seems another food has added calcium," says Bonnie Liebman, nutrition director for the Center for Science in the Public Interest. Consumers seem to love the idea; among Tropicana's chilled juices, sales of the calciumfortified varieties are growing at three times the rate of the others. And about 20 million U.S. households are taking calcium supplements.
