Genetically modified crops mat food more nutritious by adding genes to produce more vitamin that the body needs for health and growth. For example, a kind of rice called golden rice has been genetically modified to contain vitamin A. Regular rice does not have vitamin A, and some people who live mostly on rice are missing this important vitamin. This new rice can make a big difference to those people. Modifying potatoes to contain less starch would make French fries healthier because they would not absorb so much fat in the cooking. Genetically modified vegetables of the future may be produced with added nutrients to help fight heart disease and cancer.
