If there is a grain that has superpowers, barley is at the very top of the list. Not because it’s a trendy fad, but because it contains precisely the nutrients the body urgently needs: fiber, minerals, vitamins, antioxidants, and substances that are proven to protect the heart. Even our great-grandfathers cooked it, drank it as barley water, and used it for digestion, and today these benefits are also confirmed by research.
Barley - a grain with history returning to modern kitchens
Barley is one of the world’s oldest grains. Archaeologists have found evidence of its use more than 10,000 years ago. Sometimes it was even more important than wheat. It was used in soups, to thicken stews, as the base of porridges and side dishes, and also in drinks (such as barley water, which is still recommended in folk healing practices for cleansing the body).
If we look at global statistics, more than 140 million tonnes of barley are harvested every year. That’s an enormous number, but interestingly, more of it is used for animal feed and industry than for human consumption. A pity, since cooked barley is the most valuable form (especially if we use whole barley, hulled grain, pearl barley, or barley flakes). Pearl barley, the one most commonly found, is convenient but contains less fiber.
In folk medicine, barley was considered food that strengthens the heart, cleanses blood vessels, and gives strength. Today we have modern words, but the meaning remains the same.
Why is barley so healthy?
It’s full of nutrients. Barley is packed with substances that serve as your body’s natural protection. It contains:
- lots of fiber – especially beta-glucan, a very valuable soluble fiber
- B vitamins
- selenium
- copper
- magnesium
- phosphorus
- manganese
- chromium
- niacin
In addition, it contains lignans. These are plant compounds with powerful antioxidant effects. Antioxidants protect our cells from damage that can lead to aging, inflammation, and serious illnesses such as cancer and heart disease.
Beta-glucan – a term worth remembering
Beta-glucan is a special type of fiber that forms a gel-like substance in the digestive system. This means three things:
- it slows digestion
- it reduces blood sugar spikes
- it creates a feeling of fullness.
This is also why people feel full of energy, not heavy, after eating barley. A 2020 study published in the Journal of Nutrition showed that just 3 grams of beta-glucan daily lowers LDL (“bad”) cholesterol. Barley contains much more than that.
If we look at human health as a house, digestion is its foundation. In this respect, barley is truly a master. Fiber acts in two ways:
- insoluble fiber ensures that food moves more slowly through the intestines, preventing constipation and helping with regular elimination
- soluble fiber serves as food for beneficial gut bacteria.
When gut bacteria process this fiber, they produce short-chain fatty acids, which:
- nourish the cells of the gut lining
- reduce inflammation
- strengthen the immune system
- prevent some gut diseases.
In simple language: your gut feels like it’s at a wellness retreat... In a 2025 study that tracked 180 people with irritable bowel syndrome, daily consumption of barley reduced symptoms by 35% in just four weeks.
Barley and weight loss – natural help with no tricks
When it comes to weight gain, we often look at food as the culprit. But barley definitely is not! In fact, barley helps the body function better, mainly thanks to its high fiber content:
- you eat less
- you eat more mindfully
- you stay full longer.
Research shows that high-fiber meals reduce daily calorie intake by 8 to 18%, because you don’t feel a constant need to snack. Folk medicine knew this, and it’s also the reason why barley was used in fasting meals, when the body needed cleansing. Barley has been proven to lower cholesterol naturally and effectively.
When talking about cholesterol, it’s important to understand the difference between LDL (“bad cholesterol”) and HDL (“good cholesterol”). Barley reduces LDL and increases HDL.
How?
Beta-glucan binds to bile acids and removes them from the body. The liver then must make new ones, using cholesterol from the blood. That’s how its level gradually drops. In a study on 28,000 people, regular barley consumption reduced LDL by 7 to 20%, which is remarkable for a natural food.
Barley protects the heart too, with a power you’d expect from medicine
High blood pressure is a silent enemy for many. According to 2025 data, more than 32% of Europeans have high blood pressure. Barley helps lower it because it:
- regulates blood sugar
- lowers triglycerides
- reduces inflammation
- keeps blood vessels flexible.
Famous Japanese healer Dr. H. Yamamoto already pointed out in 2020 that barley is used in traditional medicine as a food that cleans blood vessels like water clears a stream. Blood sugar spikes are one of the main causes of fatigue, irritability, and weight gain.
Barley is among foods with a low glycemic index (GI), which means sugar from barley enters the blood slowly.
In a study comparing a barley breakfast with a wheat breakfast, it was found that barley caused:
- 43% less glucose spike
- 34% less insulin spike.
This means more stable energy and fewer sugar cravings.
Barley and skin health – a natural source of collagen
Collagen is a protein that maintains skin elasticity. After the age of 30, the body produces 1% less collagen each year, which is one of the main reasons for wrinkles and a tired appearance. Barley contains:
- zinc
- selenium
- B vitamins
- antioxidants.
These substances naturally boost collagen production. In eastern medical traditions, barley has been used for centuries as a food for beautiful skin. Today, this is also confirmed by research. Eating barley increases skin hydration and reduces inflammation.
Barley and colon cancer – prevention through fiber power
Research from Harvard has shown that a high-fiber diet reduces the risk of colon cancer by 27%. Barley has the most fiber among grains. How does it work?
- Speeds up the passage of food through the intestines
- reduces the contact of harmful substances with the gut wall
- supports healthy gut microbiota
- contains antioxidants that prevent cellular damage.
This is clear proof that simple foods can do a lot. Folk healing practices still recommend:
- Soaking barley overnight (8 to 12 hours is ideal)
- Light rinsing before cooking
- Sprouting (sprouting can increase nutrient content by up to 30%).
This improves digestibility and increases mineral absorption. It should also be noted that barley is one of the cheapest superfoods in the world, so it’s surprising that it can be used in soups, as a side dish, in salads, in porridge, in stews, or as the base for a home power breakfast.
Barley water used to be the most popular recovery drink. You can make it yourself: cook for 30 minutes, then strain and drink chilled. Folk stories often describe it as helping digestion, cleansing the body, and restoring energy.
Barley – the forgotten superfood making a comeback because it works
Add it to your kitchen and you’ll notice:
- more energy
- better digestion
- less blood sugar fluctuation
- clearer and more radiant skin
- greater satiety
- more stable weight
- a healthier heart.
You don’t need expensive supplements, exotic powders, or trendy diets. Barley is local, simple, affordable, and healthy. It contains exactly what the body truly needs: fiber, minerals, vitamins, and antioxidants. Folk wisdom has known it for ages, and today, science only confirms it.
Include barley in your daily diet as often as possible and your body will thank you.
