From this region of West and Central Asia, it spread to India, Persia, Syria and other countries of the region. It is interesting to note that Barley beer is one of the first alcoholic beverages to have been developed by people dating back to Neolithic age.
Barley is one of the food crops which is mentioned in ancient India texts of Rig Veda and other scriptures. It is called ‘Yava’ in these ancient texts. Traces of its cultivation have also been found dated to post-Neolithic Bronze Age Civilisation and Harappa Civilisation, dating back to almost 5000 years from present.
Barley Varieties
Barley is grown as a summer crop in temperate latitudes and as a winter crop in tropical latitudes. Three varieties of Barley grown are – Hordeum vulgare, Hordeum distichum and Hordeum irregular.
In India, most important states for barley cultivation are UP, Rajasthan, MP, Bihar, Punjab, Haryana, HP and union territory of Jammu and Kashmir.
Barley is also categorised as – Pot Barley and Pearl Barley. Pot Barley has its husk or hull removed. Pearl Barley has its husk, bran layers removed and then polished. This makes Pot Barley more nutritious than Pearl Barley. Pot Barley needs to be soaked before use whereas Pearl Barley can be used directly for cooking purposes.
What are the uses of Barley?
Barley finds use as a food grain and also a fodder feed for livestock. As a food grain, it is ground to make flour. Barley or Jau flour is used to prepare different types of breads. It can also be malted which is then used as diastatic supplement for other bread flours. Diastatic process is the process of converting starch to sugar. When used along with wheat flour in baking, it adds softness to the baked product.
Barley flakes can be added to porridge. It can be added to soups. Barley flour can be mixed with other flours to make ‘rotis’ or other baked products.
In beverage industry, it is malted to make beer. Barley flour which is rich in protein is used as food whereas the one which is poor in protein is used in making beer.
Barley Flour types…
Barley flour is made from dried and ground barley. The flour is generally of two types – coarse and fine.
Coarse flour is made from groats which are milled to make it. Groats include bran of the grain and is same as hulled barley in which only the outer husk is removed.
Fine flour is made by pearling the barley. By pearling the fiber rich outer covering of the grain is removed.
A third type of flour, called Patent Barley Flour, is more finely ground and more of its outer layers are removed than in the Fine ground variety of flour. Patent flour is to be used as a feed for infants.

Potential Health Benefits of Barley flour
The advantages offered by barley flour for the health of body are derived from its impressive nutritional composition. Some of these are enumerated below…
1/12. Helps in losing weight
By making you feel fuller and enhancing satiety, it makes you control your cravings for frequent eating. This is possible because of the presence of fiber in barley. Barley contains both soluble and insoluble fiber.
Beta-glucan is a soluble fiber present in it. Once consumed, this compound forms a gel-like substance in gut, which slows down digestion and absorption of nutrients. This gives the feeling of fullness.
Insoluble fiber present in barley does not dissolve in water and adds to bulk to food. This resultant slowing down of digestion makes you feel less hungry, which means that you eat less and tend to lose weight naturally.
2/12. Improves gut health
The insoluble fiber component present in barley flour helps in easing the movement of stool as it adds bulk to stool. This prevents constipation, irritable bowel syndrome, Crohn’s disease and inflammation. It is a guard against various diseases related to digestive and excretory system.
The soluble fiber compounds are good for friendly gut bacteria which help in producing short-chain fatty acids.
3/12. Prevents gallstones
Gall bladder stones are quite common among population which often requires surgery and removal of gall bladder as a cure. However, by having fiber rich food, such as barley flour, the instance of gall bladder stones can be reduced significantly. Many studies have also proven this beneficial aspect of fiber-rich diet.
4/12. Reduces Heart Risk
How barley flour reduces the LDL cholesterol is mentioned in the point above. The soluble fiber component is also able to reduce the blood pressure levels. With cholesterol down and hypertensive blood pressure also reduced, the risk factors to heart are minimised.
5/12. Controls Diabetes
Magnesium plays a role in secretion of insulin and use of sugar in body. This reduces the sugar level of the body. Further, the insoluble fiber which slows down the process of digestion does not release sugar in blood. Both these factors play important role in controlling sugar levels, especially Type 2 diabetes.
6/12. Reduces Cholesterol Levels
One way to reduce the cholesterol levels in blood is to make liver use more of it to make bile acid. And, in order to do so, liver must have indications from the body that more bile acid is required. This happens when soluble fiber compound called beta-glucans bind themselves to the bile acids and liver requires more cholesterol from blood to secret bile acid. This not only reduces the LDL cholesterol and triglycerides but also increases the HDL (good cholesterol).
7/12. Reduces Chances of Stroke
Barley reduces the risk of having a stroke. It is one of the best sources of phytochemical called tocols, which is known to have antioxidant properties and it nullifies the free radicals present in body.

9/12. Good for bone health
Consumption of barley has also been linked to good bone health. This is believed to be due to the presence of phosphorous in the barley flour. Dietary phosphorous has the ability to strengthen bones, cell membranes, DNA and tissues of nervous system. Besides, copper, calcium and magnesium further add to the bone strength and prevent bone-related problems, such as osteoporosis.
