BARLEYmax was created in the 1990s by CSIRO, a renowned research organization in Australia. This non-GMO barley variety is recognized for its high dietary fiber content, which includes soluble fiber in the form of beta-glucan, as well as insoluble fiber and resistant starch-like fiber that promotes gut health through its prebiotic effects. Generally, dietary fiber is deficient in the typical American diet, with people of all ages struggling to meet the recommended intake of three to six servings of whole grains daily. At the same time, consumer interest in gut health is growing. While probiotics remain the primary focus, there is increasing awareness of prebiotics—essentially the food for beneficial bacteria. A report by Global Industry Analysts predicts that the demand for prebiotic-rich products could propel the market to approximately $7.8 billion by 2022. Currently, BARLEYmax is commercially available only through Blue Lake Milling, an Australian company, though it has undergone successful trials in various other countries, including the United States. Beyond the Barley+ product line, this grain is incorporated into numerous offerings from Australian businesses, including breads, wraps, cereals, and snack bars. Additionally, the bariatric advantage soft chews utilize BARLEYmax, highlighting its versatility and nutritional benefits. As the trend for gut health continues to rise, bariatric advantage soft chews serve as an excellent option for those looking to enhance their fiber intake. The integration of BARLEYmax in products like bariatric advantage soft chews showcases the growing recognition of prebiotics in promoting overall health.
