Often overlooked on grocery store shelves or used only for traditional dishes, barley hides a nutritional and healing power that is hard to match. Made from hulled whole grains such as wheat, barley, or oats, this humble grain was once a staple food in monasteries and during long fasting periods.
What is barley?
Barley is made from whole grains, especially hard wheat, barley, or oats. In this form, it retains an important part of:
- the germ (rich in vitamins E and B)
- the outer layers of the grain (containing fiber, antioxidants, and minerals)
It is a valuable source of slow-releasing energy, rich in:
- complex carbohydrates
- soluble and insoluble fibers
- vitamins B1, B3, B5, B6
- minerals (iron, zinc, magnesium, phosphorus)
- bioactive compounds: beta-glucans, lignans, saponins, phytosterols
Therapeutic Benefits
1. Aids Digestion and Regenerates Gut Flora
The insoluble fibers in barley stimulate intestinal peristalsis and act as a natural laxative. Regular consumption combats:
- chronic constipation
- bloating
- intestinal dysbiosis
STUDY: In an analysis published in World Journal of Gastroenterology (2020), it was shown that increased intake of insoluble fiber leads to a significant reduction in intestinal transit time and an increase in beneficial bacteria such as Bifidobacterium and Lactobacillus.
2. Lowers Cholesterol and Protects the Heart
Barley made from barley or oats contains beta-glucans, soluble fibers that bind to bile acids and bad fats (LDL), facilitating their elimination.
STUDY: EFSA (European Food Safety Authority) has officially approved the claim that 3g of beta-glucans/day reduces LDL cholesterol.
In a randomized clinical trial (American Journal of Clinical Nutrition, 2016), it was observed that participants who consumed barley for 6 weeks had a 12% reduction in total cholesterol.
3. Regulates Blood Sugar and Prevents Insulin Resistance
Barley has a low glycemic index (GI 25-35) and releases glucose gradually into the bloodstream. Thus:
- it stabilizes blood sugar levels
- reduces the risk of type 2 diabetes
- increases insulin sensitivity
STUDY: In Journal of Nutrition (2019), it was demonstrated that whole grains rich in beta-glucans improve glycemic response by up to 17% in overweight individuals.
4. Nourishes the Nervous System and Combats Fatigue
Barley is an excellent source of B vitamins (especially B1 – thiamine and B6 – pyridoxine), essential for:
- proper neuron function
- emotional balance
- neurotransmitter synthesis (dopamine, serotonin)
It is often recommended for individuals suffering from asthenia, chronic stress, physical and mental exhaustion.
5. Aids Weight Loss and Provides Lasting Satiety
The fibers and resistant starch in barley slow digestion and reduce appetite. It is ideal for:
- weight loss diets
- fasting regimens
- maintaining body weight
STUDY: Published in Appetite (2021), the study showed that subjects who consumed a portion of barley for breakfast ate 25% less at lunch.
6. Detoxifies the Liver and Supports Bile Production
Prepared as porridge or soup, barley has a soothing and calming effect on inflamed liver and irritated gallbladder.
It is often included in liver detoxification regimens, along with infusions of artichoke or dandelion.

Contraindications and Precautions
- Celiac Disease: Barley from wheat and barley contains gluten, which is contraindicated.
- Irritable Bowel Syndrome: May cause abdominal discomfort if consumed in excess, especially at the beginning of a high-fiber diet.
- Insufficient Cooking: Poorly cooked grains can be hard to digest and irritating to the stomach.
Recommendation: Introduce gradually into the diet and consume only well-hydrated and cooked.
