Boosting Calcium In Potatoes

posted on April 4, 2003

To all spud lovers.

The USDA is trying to boost the potato's calcium content for the health of the consumer.

Potatoes, the nation's most popular vegetable, are naturally deficient in calcium because they grow underground and most of the calcium in the soil is drawn into the above-ground stems and leaves of the plant.

Scientists identified two South American types of wild potatoes with high calcium intake and they are working to isolate the vegetable genes that control calcium retention.

The average American eats more than 140 pounds of potatoes every year.
