Barley

Health Benefits

When the weather's cold, a big pot of soup simmering on the stove warms the heart as well as the hearth. Adding some whole grain barley to the pot will improve your health along with the flavor of whatever soup or stew you're cooking. In addition to its robust flavor, barley's claim to nutritional fame is based on its being a very good source of fiber and selenium, and a good source of phosphorus, copper and manganese.

Barley's Fiber for Regularity, Lower Cholesterol, & Intestinal Protection

Wish you were more regular? Let barley give your intestinal health a boost. In addition to providing bulk and decreasing the transit time of fecal matter, thus decreasing the risk of colon cancer and hemorrhoids, barley's dietary fiber also provides food for the "friendly" bacteria in the large intestine. When these helpful bacteria ferment barley's insoluble fiber, they produce a short-chain fatty acid called butyric acid, which serves as the primary fuel for the cells of the large intestine and helps maintain a healthy colon. These helpful bacteria also create two other short-chain fatty acids, propionic and acetic acid, which are used as fuel by the cells of the liver and muscles.

The propionic acid produced from barley's insoluble fiber may also be partly responsible for the cholesterol-lowering properties of fiber. In animal studies, propionic acid has been shown to inhibit HMG-CoA reductase, an enzyme involved in the production of cholesterol by the liver. By lowering the activity of this enzyme, propionic acid helps lower blood cholesterol levels.

In addition, barley's dietary fiber is high in beta glucan, which helps to lower cholesterol by binding to bile acids and removing them from the body via the feces. Bile acids are compounds used to digest fat that are manufactured by the liver from cholesterol. When they are excreted along with barley's fiber, the liver must manufacture new bile acids and uses up more cholesterol, thus lowering the amount of cholesterol in circulation. Soluble fiber may also reduce the amount of cholesterol manufactured by the liver.

A study published in the American Journal of Clinical Nutrition suggests barley's fiber has multiple beneficial effects on cholesterol. In this study of 25 individuals with high cholesterol (postmenopausal women, premenopausal women, and men), adding barley to the American Heart Association Step 1 diet resulted in a significant lowering in total cholesterol in all subjects, plus their amount of large LDL and large and intermediate HDL fractions (which are considered less atherogenic) increased, and the smaller LDL and VLDL cholesterol (the most dangerous fractions) greatly decreased.
Lastly, when barley provides insoluble fibers that feed friendly bacteria in the digestive tract, this helps to maintain larger populations of friendly bacteria. In addition to producing the helpful short-chain fatty acids described above, friendly bacteria play an important protective role by crowding out pathogenic (disease-causing) bacteria and preventing them from surviving in the intestinal tract.

History

Barley originated in Ethiopia and Southeast Asia, where it has been cultivated for more than 10,000 years. Barley was used by ancient civilizations as a food for humans and animals, as well as to make alcoholic beverages; the first known recipe for barley wine dates back to 2800 BC in Babylonia. In addition, since ancient times, barley water has been used for various medicinal purposes.

Barley played an important role in ancient Greek culture as a staple bread-making grain as well as an important food for athletes, who attributed much of their strength to their barley-containing training diets. Roman athletes continued this tradition of honoring barley for the strength that it gave them. Gladiators were known as hordearii, which means "eaters of barley." Barley was also honored in ancient China as a symbol of male virility since the heads of barley are heavy and contain numerous seeds.

Since wheat was very expensive and not widely available in the Middle Ages, many Europeans at that time made bread from a combination of barley and rye. In the 16th century, the Spanish introduced barley to South America, while the English and Dutch settlers of the 17th century brought it with them to the United States.

Today, the largest commercial producers of barley are Canada, the United States, the Russian Federation, Germany, France and Spain.
