BARLEYmax, a barley cultivar with high dietary fiber content, was developed in the 1990s by the CSIRO, a renowned Australian research institution. This non-GM barley is particularly rich in dietary fiber, including soluble fiber such as beta-glucan, insoluble fiber, and resistant starch-like fiber, which is believed to have prebiotic effects that can enhance gut health. The average American diet is notably deficient in fiber, with individuals of all ages struggling to meet the recommended intake of three to six servings of whole grains daily. As consumer interest in gut health increases, the focus has primarily been on probiotics; however, there is a growing awareness of prebiotics—the nourishment for beneficial bacteria. According to a report by Global Industry Analysts, the demand for prebiotic-rich products could propel the market to reach $7.8 billion by 2022. Currently, BARLEYmax is commercially available through Blue Lake Milling, an Australian company, and has been successfully tested in several countries, including the United States. In addition to the Barley+ range, this grain is also utilized in various products from other Australian companies, such as breads, wraps, cereals, and snack bars. With the rising popularity of products like Citracal Slow, which offers additional digestive benefits, the integration of BARLEYmax into these offerings could further enhance their appeal and effectiveness.
