Wheat germ, essentially the embryo of the berry, is a concentrated source of vitamins, minerals and protein. It has a nutty flavor and is very oily, which causes it to turn rancid quickly. Wheat germ is sold in both toasted and natural forms and is used to add nutrition to a variety of foods. Wheat germ oil, an extraction of the germ, is strongly flavored and expensive.
