When the grain is dried through a process known as malting, it becomes a crisp cereal.  Barley is also used in the brewing process of beer and whiskey.  It can also be smoked with wood chips to bring out its nutty flavor and served alongside grilled meats like beef or lamb. Barley can be substituted for pretty much any other whole grain. Some people even like to use it in risotto instead of rice.

This grain offers a number of surprising health benefits.  For example, it is high in fiber, especially beta-glucan, which helps lower cholesterol and blood sugar levels.

Fights Chronic Disease

Eating whole grains, like hulled barley, has been associated with a decreased risk of chronic diseases. Hulled barley contains beta-glucan, a fiber which may help lower cholesterol and blood sugar.  Stable blood sugar levels help prevent the onset of diabetes.

Aids in Digestion

Barley is high in fiber, a nutrient that is vital for healthy digestion. Research shows that consuming barley can relieve constipation, improve certain bowel conditions and increase the activity of beneficial bacteria in the gut.

Promotes Heart Health

Because barley is high in soluble fiber, it helps lower cholesterol levels.  Soluble fiber has been shown to lower total cholesterol and “bad” LDL cholesterol significantly.

One study conducted by Frontier Laboratories of Value Creation in Japan looked at a group of 44 men with high cholesterol.  It was found that those who ate a mixture of rice and pearled barley reduced unhealthy LDL cholesterol and decreased belly fat, compared to the control group that consumed rice alone.

Side Effects

Barley and other whole grains are healthy additions to most diets. However, people with celiac disease or other intolerances to other grains like wheat should refrain from consuming barley.

Individuals who take blood-sugar-lowering medications should also exercise caution.

Furthermore, barley contains short-chain carbohydrates known as fructans, a fermentable type of fiber. Fructans are known to cause gas and bloating in people with digestive disorders, such as irritable bowel syndrome (IBS).  For this reason, IBS sufferers may choose to avoid barley.

Hulled Barley vs. Pearl Barley: Which is Healthier?

Whole-grain, hulled barley is healthier than refined, pearled barley.  Hulled barley has only the inedible outer shell removed during processing, so it is still considered a whole grain. On the other hand, pearled barley is not a whole grain because the bran has been removed.

While pearled barley may still be a decent source of nutrients, hulled barley is a much healthier option, as whole grains have been linked to heart health and a lower risk of chronic diseases.

How to Cook Barley:

Pearl Barley:

  1. Combine 1 cup barley with 2 1/2 cups water or broth in a small pot and bring to a rolling boil. (There is no need to soak barley, pearled or not.)
  2. Once boiling, reduce heat to a simmer and cook, covered, until tender (about 40 or 50 minutes). 
  3. Once most of the liquid has been absorbed, let stand for 5 minutes.

Quick Cooking Barley:

  1. Bring 1 3/4 cups water or broth to a boil in a small pot or saucepan. 
  2. Add 1 cup barley.
  3. Reduce heat to a simmer and cook, covered, until tender for about 10 to 12 minutes.

Is Barley Good for Weight Loss?

Both pearled barley (with the bran removed) and “quick-cooking” (parboiled) barley both contain a decent amount of soluble fiber, which can help you slim down.

In one small Japanese study, eating barley helped the participants reduce their cholesterol levels, shrink their midsections, and significantly reduce harmful visceral fat. 

Because the human body cannot digest fiber, foods high in fiber add volume to your diet without increasing calories. This makes high-fiber foods very filling, which is useful for people trying to lose weight. 

Another reason barley promotes fullness is that it decreases the levels of ghrelin – the hormone that makes you feel hungry.

Is Barley Safe for Diabetics?

Research shows that regular consumption of barley may lower blood sugar and insulin levels.  The grain has a low glycemic index, making it a smart choice for people with diabetes or those at risk of developing diabetes.

Whole-grain barley is a good source of the soluble fiber known as beta-glucan.  This special type of fiber helps slow the absorption of sugar by binding with it in your digestive tract.

A study conducted by the US Dept. of Agriculture in Albany, California looked at the effects of barley on blood sugar.  A group of 17 obese women with an increased risk of insulin resistance who consumed a breakfast cereal containing 10 grams of beta-glucan from barley significantly decreased blood sugar levels more than other types of grain cereals.
