Pretty much all grain starts out whole. Some grains are refined after harvest, however, to remove the inner and outermost layers (germ and bran) leaving only the endosperm layer. This removes many of the health benefits of grain. Most whole grain foods contain all three layers, meaning the body can potentially get more of these benefits. When at least half of the grains you eat are whole you get a unique combination of substances including fiber, phytonutrients and antioxidants. More about the three layers:
Bran layer
The coarse, outer layer of the kernel includes concentrated amounts of several nutrients:
- Fiber
- B vitamins
- Minerals
- Protein
- Phytonutrients (naturally occurring plant substances that have potential health benefits)
Endosperm layer
The middle layer (and the largest section) serves as the main energy storehouse for the plant. It contains:
- Carbohydrates
- Protein
- Small amounts of B vitamins
Germ layer
Although it's the smallest part of a grain, the germ is packed with nutrients. The germ sprouts into a new plant, so it holds rich supplies of key nutrients:
- Minerals
- B vitamins
- Vitamin E
- Phytonutrients
More than individual nutrients and phytochemicals, all three parts of the grain working together bring the most potential health benefits.
How can we help?
All Big G cereals have at least 8 grams of whole grain per serving; at least 48 grams are recommended daily.
