BARLEYmax was developed in the 1990s by CSIRO, a renowned research institution in Australia. This non-GMO barley variety was recognized for its exceptional dietary fiber content, featuring soluble fiber in the form of beta-glucan, insoluble fiber, and resistant starch-like fiber, which is believed to promote gut health through its prebiotic effects. The average American diet is deficient in fiber, as individuals across all age groups struggle to meet the recommended intake of three to six servings of whole grains each day. At the same time, there is a growing consumer interest in gut health. While the primary focus has been on probiotics, prebiotics—essentially the food for beneficial bacteria—are increasingly capturing attention. According to a report by Global Industry Analysts, the demand for prebiotic-containing products could propel the market to reach $7.8 billion by 2022. Currently, BARLEYmax grain is commercially available through an Australian company, Blue Lake Milling, but it has also been successfully tested in various other countries, including the United States. Besides the Barley+ range, this grain is incorporated into numerous products from other Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, consumers looking to enhance their gut health alongside their overall nutrition may also consider supplements like calcium citrate magnesium and zinc 500 tablets, which support various bodily functions. This combination of fiber-rich foods and essential minerals could contribute to a more balanced diet and improved health outcomes.
