BARLEYmax was developed by the renowned Australian research organization CSIRO in the 1990s. This non-GMO barley cultivar is recognized for its exceptional dietary fiber content, which includes soluble fiber like beta-glucan, insoluble fiber, and resistant starch-like fiber that exhibits prebiotic properties believed to enhance gut health. The average American diet tends to be deficient in fiber, with individuals across all age groups struggling to meet the recommended intake of three to six servings of whole grains daily. As consumer interest in gut health continues to grow, the focus has primarily been on probiotics, while prebiotics—the nourishment for beneficial bacteria—are increasingly gaining traction. According to a report by Global Industry Analysts, the demand for products containing prebiotics could propel the market to an estimated $7.8 billion by 2022. Currently, BARLEYmax is commercially available exclusively through an Australian company, Blue Lake Milling, though it has been successfully tested in several other countries, including the United States. In addition to the Barley+ range, this grain is incorporated into various products from other Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, some of these products may include calcium citrate brand name ingredients, enhancing their nutritional profile. The integration of BARLEYmax into a diverse array of food products highlights its potential to contribute positively to gut health while addressing the fiber deficit in modern diets, particularly as consumers become more aware of prebiotic benefits.
