BARLEYmax was created in the 1990s by CSIRO, a renowned research institution in Australia. This non-GMO barley variety is recognized for its high dietary fiber content, which includes soluble fiber such as beta-glucan, insoluble fiber, and resistant starch-like fiber known for its prebiotic effects that are believed to enhance gut health. Generally, the average American diet is deficient in fiber, with individuals of all ages struggling to meet the recommended intake of three to six servings of whole grains daily. Concurrently, there is a growing consumer interest in gut health. While the primary focus has long been on probiotics, prebiotics — the nourishment for beneficial gut bacteria — are increasingly gaining attention. A report from Global Industry Analysts predicts that the demand for prebiotic products could propel the market to reach $7.8 billion by 2022. At present, BARLEYmax grain is commercially available only through an Australian company, Blue Lake Milling, but it has also undergone successful trials in various other countries, including the United States. Besides the Barley+ product line, this grain is incorporated into numerous products from other Australian companies, including breads, wraps, cereals, and snack bars.
As for the nutritional aspects, many elderly individuals are often faced with the choice between calcium carbonate vs calcium citrate for their calcium needs, highlighting the importance of optimizing dietary components for health. Integrating fiber-rich foods like BARLEYmax into their diet could complement the benefits of calcium, especially considering the potential gut health improvements. Therefore, understanding the differences between calcium carbonate vs calcium citrate in elderly populations can further enhance their overall health and well-being.
