American scientists have succeeded in developing carrots significantly richer in calcium but more research is necessary before we can buy these enriched veggies from the market.
Scientists at Texas A & M University and Baylor College of Medicine set out to produce calcium-enriched carrots through genetic engineering and their preliminary experimentations seem to have been a success, according to a study appearing in this week's online early edition of Proceedings of the National Academy of Sciences.
In the researchers’ experiment, adults consumed genetically modified carrots and normal carrots alternatively for a period of time. They found that participants absorbed 41 percent more calcium from the enriched carrots than from the normal ones.
Unlike the carrots the scientists modified, normal carrots do not contain a significant amount of calcium. The calcium-rich carrots however are not ready for wide distribution yet, the authors said, requiring further safety trials.
“These carrots were grown in carefully monitored and controlled environments,” said Professor Kendal Hirschi, part of the team at the Baylor College of Medicine in Texas, in a news release. “Much more research needs to be conducted before this would be available to consumers.”
Calcium consumption is essential in that it helps protect bones from brittle bone disease and osteoporosis. It is found primarily in dairy products, leafy green vegetables such as broccoli and collard greens, oranges as well as fortified foods and supplements.
Osteoporosis, which is a disease of the bone characterized by fragility and risk of fracture, is one of the world's most prevalent nutritional disorders, the scientists said. An increased calcium intake is essential in treating the disease.
Until the Texas researchers’ genetically modified carrots are ready, those suffering from osteoporosis can be more careful about their diet and about exercising, which is also recommended as a way of maintaining the bones’ health. Experts also advise quitting smoking and consuming alcohol in moderation.
