Carrots are rich in dietary fibers, minerals and vitamins. So far, they have been genetically modified to resist pests, fungi and to increase herbicide tolerance. With latest genetic improvements, carrots could become important source of another element essential for human health - calcium. Carrots are rich in calcium, but without proper calcium carriers it couldn’t be maximally absorbed. Increased level of proteins that act like carriers would increase calcium bioavailability. Experiments with mice showed that genetically altered carrots provide 50% more calcium than regular carrots. Test with human showed that genetically modified carrots offer 41% more calcium compared to unaltered plants. Calcium and vitamin D are necessary for the proper bone metabolism and adequate bone mineral density. Osteoporosis is famous and widespread disease resulting from lack of calcium in the bones; it is usually treated by various calcium containing pills. Genetically modified plants would simplify the procedure by providing calcium directly from the meal. Calcium “enriched” carrots are still not available.
