Barley is a cereal grain that people can use in bread, beverages, stews, and other dishes. As a whole grain, barley provides fiber, vitamins, and minerals. These offer various health benefits.
This article looks at barley's nutritional content and benefits, and it lists some reasons that some people may need to avoid consuming it. It also provides some tips on using and preparing it, as well as some recipes.
Stores usually sell barley in two forms: hulled and pearled.
Hulled barley undergoes minimal processing to remove only the inedible outer shell, leaving the bran and germ intact.
Pearled barley has neither the hull nor the bran.
The table below shows the nutrients per 100 grams (g) of uncooked hulled and pearl barley.
It is important to note that barley will usually expand to three and a half times its volume when cooked. Typically, a person will eat half a cup of cooked barley weighing around 78.5 g.
The table also shows the daily recommended intake of nutrients for adults aged 19 years and above, according to the 2015–2020 Dietary Guidelines for Americans. Individual recommendations will vary according to age, sex, activity levels, overall health status, and other factors.
|Nutrient||Hulled barley||Pearl barley|
|Calcium (milligrams [mg]) ||33||29||1,000–1,200|
|Selenium (micrograms [mcg])||37.7||37.7||55|
Barley is also a rich source of B vitamins, including niacin, thiamin, and pyridoxine (vitamin B-6). It also contains beta-glucans, a type of fiber that

Various nutrients in barley support the cardiovascular system. These include:
Vitamins and minerals
Folate and iron are particularly important for forming red blood cells and oxygenating the blood, which is important for overall heart health.
Niacin, riboflavin, thiamin, folate, iron, magnesium, and selenium all enhance the processes of cell formation, such as carrying oxygen through the blood, and the functioning of the immune system. Barley is a good source of all these nutrients.
Sodium and potassium
The American Heart Association (AHA) recommend avoiding foods that are very high in sodium, such as fast foods. Instead, consuming vegetables, fruits, grains, and other potassium-rich foods may help maintain healthy blood pressure.
Fiber appears to boost heart health by helping manage blood pressure and controlling cholesterol levels.
More specifically, the beta-glucan fiber present in barley reduces low density lipoprotein, or "bad," cholesterol by binding to bile acids and removing them from the body via excretion. In fact, according to one 2008
In 2008, researchers found that eating a lot of high beta-glucan pearled barley significantly reduced high serum cholesterol levels and lowered visceral fat in Japanese men. These are both risk factors for cardiovascular disease.
For example, zinc
According to the
Selenium also acts as an antioxidant, protecting cells against damage caused by molecules called free radicals. This type of damage may increase the risk of cancer.
For this reason, some people believe that consuming foods that contain beta-glucans may help prevent cancer. However, more research is needed to confirm this potential health benefit.

Barley is a versatile grain with a nutty flavor and a chewy, pasta-like texture. People can prepare it in various ways.
In the sections below, we list some preparation methods for different types of barley.
Hulled barley has a chewier consistency than pearled barley. It needs longer soaking and cooking times due to its outer bran layer.
Soaking will reduce the cooking time and achieve optimal flavor and texture.
To prepare hulled barley:
- Put the barley in a pan with twice its volume of water.
- Leave it to soak for several hours.
- Drain and rinse before cooking.
- Add 1 cup of grain to 3 cups of water or broth.
- Bring it to a boil.
- Reduce the heat and let it simmer for around 45 minutes.
To prepare pearled barley, follow the same process as for hulled barley but without soaking it. Cooked from dry, a cup of barley will need 3 cups of liquid.
Here are some tips for using barley:
- After cooking, add it to any pot of soup or stew to give it body and flavor.
- Cook it in broth and add vegetables to make a tasty pilaf or risotto.
- Toss chilled, cooked barley with diced vegetables and homemade dressing for a quick cold salad.
- Combine barley with onion, celery, mushrooms, carrots, and green pepper. Add broth to the mixture, bring it to a boil, and then bake for approximately 45 minutes for an easy and healthful barley casserole.

Barley contains gluten, so it is not suitable for people with celiac disease, a wheat allergy, or a nonceliac gluten sensitivity. Malt, malted beverages such as beer, and several flavorings use barley as a base. As a result, they too contain gluten.
It is also important that people who want to

I have heard that barley can improve the skin and hair. Is this true?
Currently, there is no scientific evidence directly linking barley intake to improved skin or hair health. However, barley may improve the health of skin and hair because it contains many nutrients that are important for these features.
For example, barley contains an amino acid called lysine. This is necessary for the formation of collagen, the most abundant protein in the body. Collagen gives skin structure and elasticity. Barley also contains selenium, a mineral that doubles as a powerful antioxidant, which helps protect skin cells from free radical damage. It also contains zinc, B vitamins, and iron, all of which are essential for promoting the health of skin and hair.Jillian Kubala, MS, RD Answers represent the opinions of our medical experts.
