The germ of the wheat kernel is packed with nutrients because it is the primary source of nutrition for the kernel.
Features
A one-ounce serving of raw wheat germ provides about 101 calories, 6 grams of protein, 3 grams of fat and 4 grams of fiber. Wheat germ is also a good source of B vitamins and minerals such as iron and zinc.
Types
Wheat germ is found in whole wheat and whole-wheat flour, and is sold separately as raw or toasted flakes. Wheat germ oil, extracted from the germ, is a concentrated source of vitamin E and omega-3 fatty acids. It's sold as a nutritional supplement.
Significance
Wheat germ contributes important nutrients that may be missing in a low-carbohydrate diet or any diet that eliminates starchy foods like breads and other baked goods made with flour. For this reason, those on low-carb diets will often supplement it with wheat germ.
Considerations
Although milling removes the germ and its nutrients from white flour, the missing nutrients are added back in by the food processors through a fortification process.
Misconceptions
Fermented wheat germ extract (WGE), a dietary supplement promoted as a cancer treatment, does not have the same nutritional profile as wheat germ or wheat germ oil, and should be taken under medical supervision.
