Barley, a grain with medical and dietary benefits

Barley is a grain with medical and dietary benefits. The nutritional value of barley has attracted the public’s attention in recent years. Many studies have shown that barely can improve the intestinal environment, relieve constipation, and reduce visceral body fat.

In 2007, research from Japan showed that barley could reduce visceral body and low-density lipoprotein cholesterol. Forty-four hypercholesterolemic Japanese men with a body mass index above 22 kg/m2 (weight in kilograms and height in meters squared) were randomly assigned to two groups.

The test group consumed rice mixed with barley, and the placebo group consumed rice without barley for 12 weeks. The results showed that compared with the placebo group, the visceral body fat and low-density lipoprotein cholesterol were reduced in the test group.

A second type of barley, called glutinous barley, is also beneficial to health, as revealed by research conducted by the Western Japan Research Center. The research was published in the Journal of Physiological Anthropology in 2017.

Per guidelines from the research team, caregivers in a retirement home provided elderly residents with rice mixed with glutinous barley as a staple food for five months.

The research found that among the 28 elderly on the diet, whose average age was 89, 14 who suffered from constipation increased their number of bowel movements significantly, with a monthly increased average of 9.2 times to 12.1 times indicating that sufficient dietary fiber intake, such as that provided by the barley, could promote the elderly’s peristalsis. Also, the use of laxatives was reduced remarkably.

Barley is rich in carbohydrates, protein, soluble dietary fiber β-glucan, insoluble dietary fiber, vitamin B, and more. Dietary fiber is beneficial to the body and helps to relieve constipation and reduce weight. The β-glucan in barley can inhibit the rise of postprandial blood glucose levels, reduce cholesterol levels, and feed the intestinal bacteria, thus regulating the intestinal environment and improving peristalsis.

Health and Longevity

Improving the intestinal environment is not only a matter of correcting constipation—maintaining good intestinal gut microbiota also plays an important role in overall health.

Japan ranks among the countries with the highest life expectancies in the world. More specifically, the number of centenarians in Kyotango city is three times more than that in Kyoto Prefecture. According to the Kyotango government statistics, there are 124 centenarian citizens as of Sept. 1, 2022, and 237 centenarians in every 100,000—3.3 times higher than the national level in the rest of Japan.

Prof. Yuji Naito, Department of Research, Kyoto Prefectural University of Medicine, studied the “secrets” of the centenarians in Kyotango city. He discovered significantly more Clostridium butyricum in the elderly’s intestines than in the elderly in the adjacent Kyoto city.

Yuji surmised that the local elderly had a large amount of Clostridium butyricum in their gut microbiota associated with the high fiber in their diet. The metabolism of Clostridium butyricum can increase the number of immunocytes and reduce inflammation, it also functions as protection for the cerebrum and the central nervous system. “Maybe this is one of the critical reasons for their longevity.”

Dietary fiber is relatively abundant in vegetables but less so in foods such as fish and meat. An effective way to intake dietary fiber is to eat barley, brown rice, germ rice, or whole wheat bread as staple foods and include beans, fruit, mushrooms, seaweed, dried carrot, pumpkin, burdock root, bamboo shoots, broccoli, fungus, natto (a traditional Japanese food made from whole soybeans), green beans, red beans, and shiitake mushrooms.
