Whole grains are crucial for good health. So what is in a grain and why are they crucial? This article will give you a brief overview of a whole grain, and why they're better for you than their refined versions.

The Whole Grain

A grain is the seed of a plant and a whole grain includes parts known as the germ, endosperm, and bran.

The germ is the part of the grain from which a new plant sprouts, it is the heart of the kernel. It includes some protein, polyunsaturated fat, fiber, and plenty of vitamins and minerals that are good for your body.

The endosperm makes up the majority of the grain kernel. It has small amounts of vitamins and minerals and includes most of the grain's protein.

The bran is the hard outer layer of the seed and is a rich source of dietary fiber. It also includes some starch, protein, fat, vitamins and minerals.

Whole Grains Versus Refined

Whole grains have all of these parts still intact. While refined grains have both the bran and the wheat germ removed, leaving only the endosperm, the least nutritious part.

Refined grains (like white flours and white rice) supply poor nutrition, leaving the body still hungry for good nutrition. Although, some of the "vitamins" and "minerals" are added back in after the milling process, nothing synthetic can fill in what was once there naturally. Refined grains are absorbed too quickly into the blood stream causing upsets in blood sugar levels which exhausts the pancreas and/or the adrenal glands. Also, since the bran is taken away during the refining process there is no longer much fiber in the grain either. Our body needs fiber in order to help clean out our intestines, so when refined grains are digested they act more like glue to your intestines which can cause various health problems.

Whole grains on the other hand, are much different than their refined versions. They are high in fiber, antioxidants, plant protein, vitamins, minerals, phytonutrients, many other healthful substances, and they have no cholesterol and are low in fat. They yield many of the nutrients that are low in present diets such as fiber, B vitamins, vitamin E, etc. Whole grains have also been shown to reduce the risk of stroke, heart disease and high cholesterol, high blood pressure, bowel disorders, many types of cancer, obesity and they may also help regulate blood glucose in people who have diabetes.

As you can see, whole grains have health benefits, while refined grains sound like they can kill you! The choice is obvious, eat whole grains for better overall health and nutrition.
