Barley, Easily Embracing
a Fiber-Rich Lifestyle

A Brief Introduction to Barley

If you continue to eat barley, you will experience a variety of health benefits, including constipation relief, weight loss, and prevention of lifestyle-related diseases. Barley contains a good balance of two types of dietary fiber, insoluble and soluble, and the secret of its power is β-glucan, a water-soluble dietary fiber. Its functional labeling has been approved in many countries around the world for its ability to suppress increases in postprandial blood glucose levels, lower cholesterol levels, and promote defecation.

Characteristics and Historical
Background of Barley

Barley, an ancient grain consumed worldwide, comes in various types and is utilized in diverse ways. Unlike wheat, barley contains no gluten but is rich in starch, making it suitable for rice and wheat for bread. It is commonly used in beer and barley tea. There are two main types of barley: non-waxy and waxy, each with distinct characteristics. Waxy barley, called Mochimugi in Japan is high in dietary fiber and has a sticky texture, while non-waxy barley, like oshimugi, is light and used in dishes like mugi toro gohan (rice with barley grated yam) in Japan.

Health Benefits of Barley

Gut Health with Barley

Barley promotes regular bowel movements by softening stools and increasing bulk.
Barley contains a balanced mix of insoluble and soluble dietary fibers. Insoluble fiber adds bulk to stools and enhances the peristaltic movement of the intestines. Additionally, water-soluble fibers in barley, such as “β-glucan,” act as nourishment for intestinal bacteria, fostering a balanced gut environment and improving intestinal motility. Scientific studies support the claim that consuming barley leads to increased stool volume and effectively alleviates constipation.

Effective Prevention of Metabolic Syndrome

Barley’s ability to regulate blood sugar levels effectively helps prevent diabetes. Additionally, β-glucan, a water-soluble dietary fiber, in barley impedes fat absorption in the intestines, aiding in the prevention of lipid irregularities and arterial hardening.

Soluble fiber is food for the bacteria in your large intestine, such as “lactic acid bacteria” and “Bifidobacterium”. When lactic acid bacteria and Bifidobacterium increase, the influence of gut flora that produces toxins and gas weakens and diminishes, therefore improving the condition of your digestive system.

Soluble fiber surrounds sugars and fats, hampering them from being broken down in the small intestine by digestive enzymes. Sugars and fats cannot be absorbed unless they are broken down, which means that the amount of sugars and fats absorbed is reduced. In this way soluble fiber helps regulate blood sugar and cholesterol.

Lowering Bad Cholesterol (LDL)

Barley’s β-glucan lowers cholesterol by binding to cholesterol and bile acids in the small intestine, inhibiting their absorption and facilitating elimination from the body. The chart illustrates cholesterol levels in groups consuming barley rice (50%) versus white rice continuously for 12 weeks. The findings demonstrate a notable reduction in total cholesterol and LDL-cholesterol levels among the barley rice group.

Recipe

Cooking Raw Barley Boiling Method
Boiling barley in plenty of water, much like pasta, makes it perfect for dishes like soups and salads. It’s convenient to cook a batch at once as you can use it in various ways.

Steps for Boiled Barley
  • Bring water to a boil in a pot and add the barley.
  • Reduce heat to a simmer, stirring occasionally, and boil for 15-20 minutes.
