A GM corn strain has twice the protein and half the carbs:
"Surprisingly, not only did we observe rescue of flower abortion but the kernels produced from pairs of flowers fused into a single normal-sized kernel that contained two embryos and a smaller endosperm," said Gallie. "Because it is the embryo that contains the majority of protein and oil, the presence of two embryos doubles their content in corn grain. The reduction in the size of the endosperm in the kernel, the tissue that contains most of the carbohydrate, means that the nutritional value of the grain has been improved considerably."
