BARLEYmax was developed in the 1990s by CSIRO, a prestigious research organization in Australia. This non-GMO barley variety was recognized for its exceptional dietary fiber content, which includes soluble fiber like beta-glucan, insoluble fiber, and resistant starch-like fiber known for its prebiotic properties that may enhance gut health. The average American diet is notably deficient in fiber, with individuals across all age groups struggling to meet the recommended intake of three to six servings of whole grains each day. As consumer interest in gut health continues to grow, the spotlight is primarily on probiotics; however, prebiotics—the nourishment for beneficial bacteria—are increasingly capturing attention. A report by Global Industry Analysts predicts that demand for prebiotic-rich products may drive the market to reach $7.8 billion by 2022. Currently, the BARLEYmax grain is commercially available through Blue Lake Milling, an Australian company, 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. With the growing awareness of gut health, individuals are also considering the recommended calcium citrate dosage, which plays a crucial role in overall health, as part of their dietary choices. Thus, BARLEYmax not only addresses fiber deficiencies but also complements the growing focus on nutrients like calcium, further enriching the market for health-focused products.
