Grains are actually the seeds of grasses, which are cultivated for food. They come in many shapes and sizes, from large kernels of popcorn to small amaranth seeds. As previously mentioned, whole grains are complex carbohydrates, they have all their parts, the germ, bran and endosperm.
The bran is a multilayered, shell-like coating of the kernel, rich in antioxidants (free radical destroyers), B vitamins (folate), and fiber (slows down sugar absorption), it protects the inside of the grain from damage by sunlight, bugs, and disease. The germ is flavorful and nutrient-packed. It’s rich in protein (building blocks of the body), healthy fats (necessary for fertility), vitamins (necessary for just about everything in the body), and phytochemicals (potent disease super heroes). The endosperm is the big starchy part of the grain, it contains mainly carbohydrates (the bodies main source of energy), along with some protein (non-heme iron) and small amounts of vitamins and minerals (necessary for all body processes). Did I make my point about how healthy whole grains are??
When whole grains are processed into white flour the endosperm is all that is left. Without the bran, the fiber is lost, along with its ability to slow down the absorption of glucose, this wrecks havoc on your energy levels, your fat cells and your brain functions. Also lost are the antioxidants that destroy free radicals and many essential minerals such as magnesium, selenium, copper and manganese as well as enzymes, iron, dietary fiber, vitamins E and B-complex and phytonutrients. Whole grains are made up of 100’s of molecules that digestion needs to break down before they can be used by our bodies so, we get a slow release of glucose and sustained energy. When they are processed into white flour they become short chains and release glucose quickly causing a spike in blood sugar and then the crash.
Whole grains have been a central element of the human diet since early civilization. Humans ceased being hunter-gatherers and settled down into farming communities when they were able to cultivate grain crops. In the Americas, corn was the staple grain, in India and Asia, they ate rice, in Africa, people ate sorghum, the Middle East, they made pita bread, tabouli and couscous, in Europe, corn, millet, wheat, rice, pasta, dark breads, Scotland, oats were a staple food, and in Russia, they ate buckwheat or kasha.
The medical evidence is clear that whole grains offer such diverse benefits as reduced risk of heart disease, stroke, cancer, diabetes and obesity as well as increased fertility. People who eat whole grains regularly have a lower risk of obesity as well as lower cholesterol levels.
Although fruits and vegetables contain disease-fighting phytochemicals and antioxidants, whole grains are often an even better source of these nutrients, and some valuable antioxidants not found in fruits and vegetables. Because of the phytochemicals and antioxidants, people who eat three daily servings of whole grains have been shown to reduce their risk of heart disease stroke, type 2 diabetes, digestive system cancers, and hormone-related cancers and have increased fertility.
