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 molybdenum, manganese, dietary fiber, and selenium, and a good source of copper, vitamin B1, chromium, phosphorus, magnesium, and niacin.
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 f***l 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 f***s. 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.
Barley's fiber can prevent or help with a number of different conditions. For example, when barley's fiber binds to and removes cholesterol-containing bile, this can be very beneficial for people struggling with heart disease since it forces the body to make more bile by breaking down cholesterol, thus lowering cholesterol levels.
A study published in the Archives of Internal Medicine confirms that eating high fiber foods, such as barley, helps prevent heart disease. Almost 10,000 American adults participated in this study and were followed for 19 years. People eating the most fiber, 21 grams per day, had 12% less coronary heart disease (CHD) and 11% less cardiovascular disease (CVD) compared to those eating the least, 5 grams daily. Those eating the most water-soluble dietary fiber fared even better with a 15% reduction in risk of CHD and a 10% risk reduction in CVD.
The fiber in barley can also help to prevent blood sugar levels from rising too high in people with diabetes.
